Swift5 API client for Blockfrost

Swift 5.7 SDK for Blockfrost.io API.

Installation

Swift package manager

dependencies: [
    .package(url: "https://github.com/blockfrost/blockfrost-swift.git", from: "1.0.1"),
],

targets: [
    .executableTarget(
        name: "Example",

Carthage

Run carthage update

Cartfile

github "blockfrost/blockfrost-swift" ~> 1.0.1

CocoaPods

Minimal pod version: 1.10+ Run pod install

Podfile:

pod 'BlockfrostSwiftSDK', '~> 1.0.1'

Or use GitHub, by tag:

pod 'BlockfrostSwiftSDK', :git => 'https://github.com/blockfrost/blockfrost-swift.git', :tag => '1.0.1'

or by branch:

pod 'BlockfrostSwiftSDK', :git => 'https://github.com/blockfrost/blockfrost-swift.git', :branch => 'master'

Usage

API provides the following call approaches:

a simple completion callbacks, returning Swift.Result<R, Error>, where R is defined by a particular API call.
async-await oriented calls

// import the SDK on the beginning of the file
import BlockfrostSwiftSDK

// define project-wide settings
BlockfrostStaticConfig.basePath = "https://cardano-mainnet.blockfrost.io/api/v0"  // or leave default
BlockfrostStaticConfig.projectId = "your-project-id"
let api = CardanoAddressesAPI()

_ = api.getAddressDetails(address: "addr1q8zu4smzyf2r2mfqjd6tc6vxf2p8rccdfk82ye3eut2udkw9etpkygj5x4kjpym5h35cvj5zw83s6nvw5fnrnck4cmvshkfm4y") { resp in
    switch (resp) {
    case let .failure(err):
        // TODO: handle error here, `err` contains the error 
        break
    case let .success(r):
        // `r` contains result of the call, here, it is of type `AddressContentTotal`
        break
    }
}

Async-await interface:

do {
    let result = try await getAddressDetailsAsync()
} catch let error {
    // handle error
}

Project ID can be loaded from env

BlockfrostStaticConfig.projectId = BlockfrostConfig.getEnvProjectId()  // BF_PROJECT_ID
BlockfrostStaticConfig.projectId = BlockfrostConfig.getEnvProjectIdMainnet()  // BF_MAINNET_PROJECT_ID
BlockfrostStaticConfig.projectId = BlockfrostConfig.getEnvProjectIdTestnet()  // BF_TESTNET_PROJECT_ID
BlockfrostStaticConfig.projectId = BlockfrostConfig.getEnvIpfsProjectId()  // BF_IPFS_PROJECT_ID

Default configuration for testnet, project ID is loaded from env var BF_TESTNET_PROJECT_ID

let apiAdd = CardanoAddressesAPI(config: BlockfrostConfig.testnetDefault())

Default configuration for IPFS, project ID is loaded from env var BF_IPFS_PROJECT_ID

let ipfsAdd = IPFSAddAPI(config: BlockfrostConfig.ipfsDefault())

You can also define API-specific configuration

let config = BlockfrostConfig()
config.basePath = BlockfrostConfig.URL_IPFS
config.projectId = BlockfrostConfig.getEnvIpfsProjectId()
config.retryPolicy = BlockfrostRetryPolicy(retryLimit: 10)    // specify custom retry policy

let ipfsAdd = apiAdd = IPFSAddAPI(config: cfg)

Check out Example application or integration tests for more usage examples.

Fetch All methods

Methods with paging parameters (count, page, order) have paging methods enabling to load all results, iterating over all pages in the background. The method returns list of all results once all pages have been downloaded.

let _ = api.getAssetHistoryAll(asset: "d894897411707efa755a76deb66d26dfd50593f2e70863e1661e98a07370616365636f696e73") { resp in
    switch (resp) {
    case let .failure(err):
        // TODO: handle error here, `err` contains the error 
        break
    case let .success(r):
        // `r` contains result of the call, here, it is of type `AddressContentTotal`
        break
    }
}

Advanced Fetch all

To use more advanced load-all-pages technique, you can use PageLoader class.

let loader = PageLoader<AssetHistory>(batchSize: 10)
loader.loadAll({ count, page, compl in
    // PageLoader uses lambda to load particular page
    _ = api.getAssetHistory(asset: asset, count: count, page: page, order: order, apiResponseQueue: apiResponseQueue, completion: compl)
}, completion: { compl in
    // Completion handler once all pages are loaded
    // TODO: handle the results
})

You can handle event handler to get new page results as they are loaded:

loader.progressHandler = { event in
    switch(event){
    case .started: break
    case let .pageLoaded(page):
        print(page)  // new page loaded, type: (Int, [T]) ~ page ID and list of results               
        break
    case .completed(_):
        break
    }
}

You can also cancel further loading:

DispatchQueue.global().async { loader.cancel() }
