Basic Usage

Draftsman is the NSLayoutConstraints and UIView hierarchy builder. Draftsman uses a new resultBuilder from Swift that makes the Declarative approach possible.

Basic

Creating constraints is very easy. All you need to do is call drf to get the LayoutDraft object:

myView.drf
    .left.equal(to: otherView.drf.right)
    .right.equal(with: .parent).offset(by: 16)
    .top.lessThan(with: .safeArea).offSet(8)
    .bottom.moreThan(with: .top(of: .keyboard))
    .apply()

there are two methods to end planning constraints which can be called from both any UIView or UIViewController:

func apply() -> [NSLayoutConstraint]
func build() -> [NSLayoutConstraint]

the difference between the two is apply will activate the constraints but build will only create constraints without activating them. Apply return value is discardable so it's optional for you to use the created NSLayoutConstraint or not.

You could always create a UIViewController or UIView and implement the Planned protocol, and call applyPlan() whenever you want the viewPlan to be applied:

import Draftsman

class MyViewController: UIViewController, Planned {
    
    var models: [MyModel] = []
    
    @LayoutPlan
    var viewPlan: ViewPlan {
        VStacked(spacing: 32) { 
            if models.isEmpty {
                MyView()
                MyOtherView()
                SomeOtherView()
            } else {
                for model in models {
                    MyModeledView(model)
                }
            }
        }
        .centered()
        .matchSafeAreaH().offset(by: 16)
        .vertical.moreThan(with: .safeArea).offset(by: 16)
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        applyPlan()
    }
}

ViewPlan can always be composed to make the code cleaner:

import Draftsman

class MyViewController: UIViewController, Planned {
    
    var models: [MyModel] = []
    
    @LayoutPlan
    var viewPlan: ViewPlan {
        VStacked(spacing: 32) { 
            stackPlan
        }
        .centered()
        .matchSafeAreaH().offset(by: 16)
        .vertical.moreThan(with: .safeArea).offset(by: 16)
    }

    @LayoutPlan
    var stackPlan: ViewPlan {
        if models.isEmpty {
            emptyStackPlan
        } else {
            modeledStackPlan(for: models)
        }
    }

    @LayoutPlan
    var emptyStackPlan: ViewPlan {
        MyView()
        MyOtherView()
        SomeOtherView()
    }

    @LayoutPlan
    func modeledStackPlan(for models: [MyModel]) -> ViewPlan {
        for model in models {
            MyModeledView(model)
        }
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        applyPlan()
    }
}

Working with UITableView or UICollectionView? Do it easily with Draftsman and Combine:

import Draftsman
import Combine

class MyViewController: UIViewController, Planned {
    
    @Published var models: [MyModel] = []
    
    @LayoutPlan
    var viewPlan: ViewPlan {
        Tabled(forCell: MyTableCell.self, observing: $models) { cell, model in
            cell.apply(model)
        }
        .fillParent()
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        applyPlan()
    }
}

View Hierarchy

You can create a view hierarchy while creating constraints by using the draftContent or drf.insert method and insert method for the subview draft (draftStackedContent or drf.insertStacked and insertStacked if its arranged subviews in UIStackView). Don't forget to call apply() or build(), Both will rearrange the view hierarchy but only apply() will activate the constraints created.

view.draftContent {
    UIView().drf
        .center.equal(to: .parent)
        .horizontal.equal(to: .safeArea)
        .vertical.moreThan(with: .safeArea)
        .insert {
            myView.drf
                .edges(.equal, to: .parent)
        }
}.apply()

The hierarchy of Views is just like how the closure is declared in your code. The above code actually will do the following instruction sequentially:

view create and insert a new UIView()
new UIView then will create constraints
new UIView then will insert myView
myView then will create constraints
all the constraints then will be created and activated

So if the hierarchy is written in pseudo hierarchy style, it should be similar to this:

view
|____new UIView
|    |____myView

the compatible type to be passed in the closure are:

any descendant of UIView
any descendant of UIViewController

If you pass UIViewController, it will be automatically added the UIViewController view as a child and put the UIViewController as a child of its current UIViewController. You could insert components as much as you need, it will fit all the Views just like how you write them.

Using Builder

For most of the time, you can build your view using Builder library built-in in the Draftsman by calling the property name and get back to Draftsman by calling drf again:

myView.drf
    .backgroundColor(.black)
    .drf.bottom.moreThan(to: .safeArea)
    .center.equal(to: .parent)

In case the property is not mapped then you can call builder before calling the property name:

myView.drf.builder
    .backgroundColor(.black)
    .drf.bottom.moreThan(to: .safeArea)
    .center.equal(to: .parent)

Using Combine

For most of the time, you can using Combine Publisher to automatically assign to the property by calling the property name and get back to Draftsman by calling storeAll(in:) or stored():

@Published var myText: String?
@Published var myColor: UIColor?

var cancellables: Set<AnyCancellable> = .init()

...
...

UILabel().drf
    .text(assignedBy: $myText)
    .textColor(by: $myColor)
    .storeAll(in: &cancellables)
    .center.equal(to: .parent)
    .bottom.moreThan(to: .safeArea)

The differences between storeAll(in:) and stored() is, stored() will retain the cancellable into the view itself. This better be used if you just want to subscribe this property using this method once, unless you know what you're doing.

In case the property is not mapped then you can call subscriber before calling the property name:

UILabel().drf.subscriber
    .text(assignedBy: $myText)
    .textColor(by: $myColor)
    .storeAll(in: &cancellables)
    .center.equal(to: .parent)
    .bottom.moreThan(to: .safeArea)

Basic Positioning

Positioning a View is easy. You just need to declare which anchor should have relation to others:

myView.drf
    .top.equal(to: other.drf.top)
    .right.moreThan(to: other.drf.right).offset(by: 8)
    .bottom.lessThan(to: other.drf.bottom).offset(by: 8).priority(.required)
    .left.equal(to: other.leftAnchor)
    .centerX.moreThan(to: other.centerXAnchor).inset(by: 8)
    .centerY.lessThan(to: other.centerYAnchor).inset(by: 8).identifier("centerY")

basic position anchors available from Draftsman are:

top
left
bottom
right
centerX
centerY
leading
trailing

All are available for both UIView and UILayoutGuide This can be used to create a constraint using one of these three methods:

equal(to:)
moreThan(to:)
lessThan(to:)

Those methods can accept basic NSLayoutAnchor from UIKit or use Anchor from Draftsman as long it's in the same Axis. To add a constant, use one of the offset(by:) or inset(by:) methods. offsetis the spacing going to the outer part of the anchor andinset` are spacing going to the inner part of the anchor:

For center anchor, offset and inset can be described in this picture:

You can then add priority or/and an identifier for the constraints created.

Basic Dimensioning

Dimensioning a View is easy. You just need to declare which anchor should have relation to others or constant:

myView.drf
    .height.equal(to: other.drf.width)
    .width.moreThan(to: other.drf.height).added(by: 8)
    .height.lessThan(to: anyOther.heightAnchor).substracted(by: 8).priority(.required)
    .width.equal(to: anyOther.widthAnchor).multiplied(by: 0.75).identifier("width")

basic dimension anchors available from Draftsman are:

height
width

All are available for both UIView and UILayoutGuide This can be used to create a constraint using one of these three methods:

equal(to:)
moreThan(to:)
lessThan(to:)

Those methods can accept basic NSLayoutDimension from UIKit or use dimension Anchor from Draftsman. To add a constant, use one of the added(by:), substracted(by:), or multiplied(by: ) methods. You can then add priority or/and an identifier for the constraints created.

Dimensioning can be achieved using constant too:

myView.drf
    .height.equal(to: 32)
    .width.moreThan(to: 64)
    .width.lessThan(to: 128).priority(.required).identifier("width")

Very similar except it accepts CGFloat

Combining Two or More Anchors

Creating constraints using multiple anchors is very easy, you can always combine two or more anchors and use them to create multiple constraints at once:

myView.drf
    .top.left.equal(to: other.drf.top.left)
    .bottom.left.right.moreThan(to: anyOther.drf.top.left.right)

It will be similar to single anchors, but you can only be passed Draftsman Anchor with the same Axis combination:

all same anchors combination can be related to each other
top.left, top.right, bottom.left, bottom.right and centerX.centerY are all can be related to each other
top.leading, top.trailing, bottom.leading, bottom.trailing and centerX.centerY are all can be related to each other
top.left.bottom and top.right.bottom both can be related to each other
top.left.right and bottom.left.right both can be related to each other
top.leading.bottom and top.trailing.bottom both can be related to each other
top.leading.trailing and bottom.leading.trailing both can be related to each other

There are some shortcuts for anchor combinations:

vertical is the same as top.bottom
horizontal is the same as left.right
localizedHorizontal is the same as leading.trailing
center is the same as centerX.centerY
edges is the same as top.left.bottom.right
localizedEdges is the same as top.leading.bottom.trailing
size is the same as width.height

Example:

myView.drf
    .vertical.equal(to: other.drf.vertical)
    .bottom.horizontal.moreThan(to: anyOther.drf.top.horizontal)

Sizing with size or width.height can be achieved by using CGSize too if needed:

myView.drf
    .size.equal(to: CGSize(sides: 30))

for offsets and insets, CGFloat is compatible with all. But if you need to assign it explicitly for each edge, you can always be passing something else:

VerticalOffsets for vertical anchors offsets
VerticalInsets for vertical anchors insets
HorizontalOffsets for horizontal anchors offsets
HorizontalInsets for horizontal anchors insets
AxisOffsets for cross position anchors offsets which are just a typealias of CGPoint
AxisInsets for cross position anchors insets which are just a typealias of CGPoint
EdgeOffsets for 3 and 4 position anchors offsets which is just a typealias of UIEdgeInsets
EdgeInsets for 3 and 4 position anchors insets which is just a typealias of UIEdgeInsets

Implicit Relation

You can pass just UIView or UILayoutGuide instead of Anchor explicitly and it will use the same anchor to make constraints:

myView.drf
    .vertical.equal(to: otherView)
    .bottom.horizontal.moreThan(to: view.safeAreaLayoutGuide)

In the example above, it will create equal constraints between myView vertical anchors and otherView vertical anchors, then it will create another with myView bottom and view.safeAreaLayoutGuide bottom.

Anonymous Anchor

Sometimes you don't want or even can't use anchor explicitly. In those cases, you can always use AnonymousLayout:

myView.drf
    .top.left.equal(with: .parent)
    .bottom.moreThan(with: .safeArea).offset(by: 16)
    .size.lessThan(with: .previous)

available AnonymousLayout are:

mySelf which will automatically get the current view
parent which will automatically get the current superview
safeArea which will automatically get the current superview safeAreaLayoutGuide
keyboard which will automatically get the keyboardLayoutGuide (powered by Clavier)
keyboardSafeArea which will automatically get the keyboardLayoutGuide with safeArea (powered by Clavier)
previous which will automatically get the previous view
previousSafeArea which will automatically get the previous safeAreaLayoutGuide

It's the same as a regular anchor, but it will automatically get the same anchor for an anonymous view. If you want to explicitly get a different anchor of anonymous, then you can do something like this:

myView.drf
    .top.equal(with: .top(of:.parent))
    .bottom.moreThan(with: .bottom(of: .safeArea)).offset(by: 16)
    .width.lessThan(with: .height(of: .previous))

available explicit anchors are:

left(of:)
leading(of:)
right(of:)
trailing(of:)
centerX(of:)
top(of:)
bottom(of:)
centerY(of:)
topLeft(of:)
topLeading(of:)
topRight(of:)
topTrailing(of:)
bottomLeft(of:)
bottomLeading(of:)
bottomRight(of:)
bottomTrailing(of:)
center(of:)
centerLeft(of:)
centerLeading(of:)
centerRight(of:)
centerTrailing(of:)
centerTop(of:)
centerBottom(of:)

Layout Constraints Shortcuts

There are several shortcuts for building layout constraints that can be accessed via drf:

fillParent() which shortcuts of edges.equal(with: .parent)
fillSafeArea() which shortcuts of edges.equal(with: .safeArea)
matchParentH() which shortcuts of horizontal.equal(with: .parent)
matchParentV() which shortcuts of vertical.equal(with: .parent)
matchSafeAreaH() which shortcuts of horizontal.equal(with: .safeArea)
matchSafeAreaV() which shortcuts of vertical.equal(with: .safeArea)
matchParentSize() which shortcuts of size.equal(with: .parent)
centered() which shortcuts of center.equal(with: .parent)
centeredH() which shortcuts of centerX.equal(with: .parent)
centeredV() which shortcuts of centerY.equal(with: .parent)
cornered(at:) which shortcuts of top.left.equal(with: .parent), or any other corner
widthMatchHeight() which shortcuts of width.equal(with: .height(of: .mySelf))
heightMatchWidth() which shortcuts of height.equal(with: .width(of: .mySelf))
sized(_:) which shortcuts of size.equal(with: givenSize)

UITableView and UICollectionView

Working with UITableView and UICollectionView is very easy with Draftsman. Just call renderCells and any sequence of Hashables:

UITableView().drf.renderCells(using: myArrayOfHashables) { item in
    MyTableCell.render { cell in
        cell.apply(with: item)
    }
}

Multiple cell for different item? Just render it:

UITableView().drf.renderCells(using: myArrayOfEnum) { item in
    switch item { 
    case .typeOne:
        MyTableCellOne.render { cell in
            cell.apply(with: item)
        }
    case .typeTwo:
        MyTableCellTwo.render { cell in
            cell.apply(with: item)
        }
    }
}

This applied for UICollectionView too:

UICollectionView().drf.renderCells(using: myArrayOfHashables) { item in
    MyCollectionCell.render { cell in
        cell.apply(with: item)
    }
}

This functionality is powered by UITableViewDiffableDataSource and UICollectionViewDiffableDataSource.

SectionCompatible

If you work with sectioned UITableView or UICollectionView, call renderSections instead and pass SectionCompatible sequence:

UITableView().drf.renderSections(using: myArrayOfSectionCompatibles) { item in
    MyTableCell.render { cell in
        cell.apply(with: item)
    }
}

The SectionCompatible is a protocol that declared like this:

public protocol SectionCompatible {
    associatedtype Identifier: Hashable
    associatedtype Item: Hashable
    var identifier: Identifier { get }
    var items: [Item] { get }
}

You can use Sectioned struct instead if you don't want to implement SectionCompatible:

Sectioned(myIdentifier, items: myArrayOfItems)

Render Cell using Combine

Most of the time your cell is changing overtime and you don't want to render the whole table all over again. In that case, you can use Combine Publisher instead of Sequence:

@Published var myItems: [Item] = []

...
...

UITableView().drf.renderCells(observing: $myItems) { item in
    MyTableCell.render { cell in
        cell.apply(with: item)
    }
}

Whenever the publisher publish changes, the table view will update according to the items published. This applies to renderSections too:

@Published var mySections: [Sectioned<MySection, Item>] = []

...
...

UITableView().drf.renderSections(observing: $mySections) { item in
    MyTableCell.render { cell in
        cell.apply(with: item)
    }
}

All of this are available both on UITableView and UICollectionView

Custom View

SpacerView

You can use SpacerView as a Spacer for UIStackView content:

UIScrollView().drf.insertStacked { 
    MyView()
    SpacerView(12)
    OtherView()
}

or leave the init empty if you want the spacer size to be dynamic:

UIScrollView().drf.insertStacked { 
    MyView()
    SpacerView()
    OtherView()
}

ScrollableStackView

There are custom UIView named ScrollableStackView which is a UIStackView inside UIScrollView. You can use it if you need a UIStackView that can be scrolled if the content is bigger than the container. It has 2 public init that can be used:

init(frame: CGRect)
init(frame: CGRect = .zero, axis: NSLayoutConstraint.Axis, margins: UIEdgeInsets? = nil, alignment: UIStackView.Alignment = .center, spacing: CGFloat = .zero)

Other than that, it can be used like regular UIStackView and regular UIScrollView minus the capability to change its distribution, since it needed to make sure the view behaves as it should.

Layout Helper

Some helpers can be used if you want your viewPlan shorter and less explicit. This helper will accept LayoutPlan closure so you don't need to access it via drf but directly on its init

HStacked and VStacked

HStacked and VStacked are a shortcut to create vertical and horizontal UIStackView without creating it explicitly. It has 3 public init that can be used:

init(_ stack: UIStackView = UIStackView(), @LayoutPlan _ layouter: () -> ViewPlan) {
init(margins: UIEdgeInsets? = nil, distribution: UIStackView.Distribution = .fill, alignment: UIStackView.Alignment = .fill, spacing: CGFloat = .zero, @LayoutPlan _ layouter: () -> ViewPlan)
init(margin: CGFloat, distribution: UIStackView.Distribution = .fill, alignment: UIStackView.Alignment = .fill, spacing: CGFloat = .zero, @LayoutPlan _ layouter: () -> ViewPlan)

Example:

VStacked(distribution: .fillEqually) { 
    SomeView()
    MyView()
    OtherView()
}
.fillParent()

This will be equivalent with:

UIStackView(axis: .vertical, distribution: .fillEqually).drf
    .fillParent()
    .insertStacked { 
        SomeView()
        MyView()
        OtherView()
    }

HScrollableStacked and VScrollableStacked

HScrollableStacked and VScrollableStacked are a shortcut to create vertical and horizontal ScrollableStackView without creating it explicitly. It has 3 public init that can be used:

init(_ stack: ScrollableStackView = ScrollableStackView(), @LayoutPlan _ layouter: () -> ViewPlan) {
init(margins: UIEdgeInsets? = nil, alignment: UIStackView.Alignment = .fill, spacing: CGFloat = .zero, @LayoutPlan _ layouter: () -> ViewPlan)
init(margin: CGFloat, alignment: UIStackView.Alignment = .fill, spacing: CGFloat = .zero, @LayoutPlan _ layouter: () -> ViewPlan)

Example:

HScrollableStacked(alignment: .fill) { 
    SomeView()
    MyView()
    OtherView()
}
.fillParent()

This will be equivalent with:

ScrollableStackView(axis: .horizontal, alignment: .fill).drf
    .fillParent()
    .insertStacked { 
        SomeView()
        MyView()
        OtherView()
    }

Tabled and Collectioned

renderCells, renderSections both on UITableView and UICollectionView can be created and called at init by using Tabled or Collectioned:

Tabled(forCell: MyCell.self, observing: $items) { cell, item in
    cell.apply(item)
}

This will be equivalent with:

UITableView().drf.renderCells(observing: $items) { item in
    MyCell.render { cell in
        cell.apply(with: item)
    }
}

same with UICollectionView:

Collectioned(forCell: MyCell.self, observing: $items) { cell, item in
    cell.apply(item)
}

Margined

Margined is a simple way to add a margin to any UIView. Example:

Margined(by: 12) { 
    MyView()
}
.fillParent()

This will be equivalent with:

UIView().drf.builder
    .backgroundColor(.clear)
    .drf.fillParent()
    .insert { 
        MyView().fillParent().offsetted(by: 12)
    }

Draftsman Planned

Draftsman Planned protocol is the protocol that makes any UIView or UIViewController can have its predefined view plan and applied it using the applyPlan method. The protocol is declared like this:

public protocol Planned: AnyObject {
    var planIdentifier: ObjectIdentifier { get }
    var appliedConstraints: [NSLayoutConstraint] { get }
    var viewPlanApplied: Bool { get }
    @LayoutPlan
    var viewPlan: ViewPlan { get }
    @discardableResult
    func applyPlan() -> [NSLayoutConstraint]
}

The only thing you need to implement is the viewPlan getter since everything will be implemented in extensions:

import Draftsman

class MyViewController: UIViewController, Planned {
    
    @LayoutPlan
    var viewPlan: ViewPlan {
        VStacked(spacing: 32) { 
            MyView()
            MyOtherView()
            SomeOtherView()
        }
        .centered()
        .matchSafeAreaH().offset(by: 16)
        .vertical.moreThan(with: .safeArea).offset(by: 16)
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        applyPlan()
    }
}

Every time you call applyPlan, it will always try to recreate the view to be the same as what was declared in viewPlan.

There are some typealias with Planned that you can use:

UIPlannedController which is UIViewController & Planned
UIPlannedView which is UIView & Planned

Planned Cell

PlannedCell is Planned built specifically for a cell which declared like this:

public protocol PlannedCell: Planned {
    @LayoutPlan
    var contentViewPlan: ViewPlan { get }
}

The only thing you need to implement is the contentViewPlan getter since everything will be implemented in extensions. It will skip contentView and straight into its content:

class TableCell: UITableView, PlannedCell {
    
    @LayoutPlan
    var contentViewPlan: ViewPlan {
        HStacked(margin: 12, spacing: 8) { 
            UIImageView(image: UIImage(named: "icon_test")).drf
                .sized(CGSize(sides: 56))
            VStacked(margin: 12, spacing: 4) {
                UILabel(text: "title text")
                UILabel(text: "subtitle text")
            }
        }
    }
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        applyPlan()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
        applyPlan()
    }
}

Every time you call applyPlan, it will always try to recreate the view to be the same as what was declared in viewPlan.

There are some typealias with Planned that you can use:

UITablePlannedCell which is UITableViewCell & PlannedCell
UICollectionPlannedCell which is UICollectionViewCell & PlannedCell

Planned Stack

PlannedStack is Planned built specifically for a cell which declared like this:

public protocol PlannedStack: Planned {
    @LayoutPlan
    var stackViewPlan: ViewPlan { get }
}

The only thing you need to implement is the stackViewPlan getter since everything will be implemented in extensions. It will automatically treat the plan as arrangeSubviews of the stack:

class MyStack: UIStackView, PlannedStack {
    
    @LayoutPlan
    var stackViewPlan: ViewPlan {
        UIImageView(image: UIImage(named: "icon_test"))
            .sized(CGSize(sides: 56))
        UILabel(text: "title text")
        UILabel(text: "subtitle text")
    }
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        applyPlan()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
        applyPlan()
    }
}

Every time you call applyPlan, it will always try to recreate the view to be the same as what was declared in viewPlan.

You can use UIPlannedStack since its a typealias of UIStackView & PlannedStack
