Use Sia Skynet in your iOS or macOS projects.
Skynet is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'Skynet'The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.
Once you have your Swift package set up, adding Skynet as a dependency is as easy as adding it to the dependencies value of your Package.swift.
dependencies: [
.package(url: "https://github.com/ppamorim/skynet-swift.git")
]To use Skynet features, you can use either Skynet, Registry or SkyDB.
First import the Skynet package:
import Skynet- Download a file:
// Execute the Skynet outside of the main thread.
let dispatchQueue = DispatchQueue(label: "Queue", qos: .userInitiated)
// Set a temporary file, when running in an application, you can use the documents folder.
let fileURL: URL = FileManager.default
.temporaryDirectory
.appendingPathComponent("download.json")
// Skylink for your file in the Skynet portal.
let skylink: Skylink = "AACgj3yd9W4iZXusSUXj3uV0tHq883ReS5I-tFl9m0FBDg"
Skynet.download(
queue: dispatchQueue,
skylink: skylink,
saveTo: fileURL
) { (result: Result<SkyFile, Swift.Error>) in
// Calls the completion closure in the same queue set, in this case,
// outside the main thread.
switch result {
case .success(let response):
print("File saved: \(response.fileURL)")
DispatchQueue.main.async {
//Update UI
}
case .failure(let error):
print("Error: \(error)")
}
}- Download a file (stream):
// Execute the Skynet outside of the main thread.
let dispatchQueue = DispatchQueue(label: "Queue", qos: .userInitiated)
// Set a temporary file, when running in an application, you can use the documents folder.
let fileURL: URL = FileManager.default

// Skylink for your file in the Skynet portal.
let skylink: Skylink = "AACgj3yd9W4iZXusSUXj3uV0tHq883ReS5I-tFl9m0FBDg"
var buffer = Data()
