Use KKBOX's Swift SDK in a promising way.
The project extends KKBOX's Open API Swift SDK by adopting Google's Promisises library. it provides an alternative way to do aynchronized API calls.
You can only install the extension with Swift Package Manager right now. Please add
// swift-tools-version:4.0
import PackageDescription
let package = Package(
name: "YourTargetName",
products: [
.executable(name: "YourTargetName", targets: ["YourTargetName"])
],
dependencies: [
.package(url: "https://github.com/KKBOX/OpenAPI-Swift-Promises", .upToNextMinor(from: "1.0.0"))
],
targets: [
.target(name: "YourTargetName", dependencies: ["KKBOXOpenAPISwift"], path: "./Path/To/Your/Sources")
]
)into your Package.swift file. And then run swift package update under command line.
While working with KKBOX's Open API Swift SDK, you may write code with nested callback handling like this:
_ = try? self.API.fetchAccessTokenByClientCredential { result in
switch result {
case .error(let error):
print("\(error.localizedDescription)")
case .success(_):
_ = try? self.API.fetch(track: "4kxvr3wPWkaL9_y3o_") { result in
switch result {
case .error(let error):
print("\(error.localizedDescription)")
case .success(let track):
print("\(track)")
}
}
}
}Promises fix the callback hells. After adding the extension, you can make the code above like this:
self.API.fetchAccessTokenByClientCredential().then { _ in
return self.API.fetch(track: "4kxvr3wPWkaL9_y3o_")
} .then { track in
print("\(track)")
} .catch { error in
print("\(error.localizedDescription)")
