URL: https://github.com/apache/openwhisk-runtime-swift/pull/153
# Add support for Swift 5.7
- Add new action signatures with async/await and throws
- Backward compatibility with old action signatures
### swift57Action
- Add support async to Whisk class
### swiftbuild.py
- simplify the code added by the build process to:
```swift
try await _WhiskRuntime.wiskRunLoop { jsonData in
await _WhiskRuntime.runAsyncMain(mainFunction: <action>, json: jsonData)
}
```
### swiftbuild.py.launcher.swift
- Add `_WhiskRuntime` struct
- Refactor Error messages
- Add new signatures
```swift
// Examples of Actions supported by Swift 5.7
// Action with Any Input and Any Output
func main(args: Any) -> Any {
let newArgs = args as! [String:Any]
if let name = newArgs["name"] as? String {
return [ "greeting" : "Hello \(name)!" ]
} else {
return [ "greeting" : "Hello stranger!" ]
}
}
// Async Action with Any Input and Any Output
func mainAsync(args: Any) async -> Any {
do {
//async code sleep for 1 sec
try await Task.sleep(nanoseconds: 1_000_000_000)
let newArgs = args as! [String:Any]
if let name = newArgs["name"] as? String {
return [ "greeting" : "Hello \(name)!" ]
} else {
return [ "greeting" : "Hello stranger!" ]
}
} catch {
return ["error" : error.localizedDescription]
}
}
// Async throwing Action with Any Input and Any Output
func mainAsyncThrows(args: Any) async throws -> Any {
//async code sleep for 1 sec
try await Task.sleep(nanoseconds: 1_000_000_000)
let newArgs = args as! [String:Any]
if let name = newArgs["name"] as? String {
return [ "greeting" : "Hello \(name)!" ]
} else {
return [ "greeting" : "Hello stranger!" ]
}
}
struct Input: Codable {
let name: String?
}
struct Output: Codable {
let count: Int
}
// Action with Codable Input and completion with Codable Output and Error
func mainCompletionCodable(input: Input, completion: @escaping (Output?,
Error?) -> Void) -> Void {
if let name = input.name {
let output = Output(count: name.count)
completion(output, nil)
} else {
let output = Output(count: 0)
completion(output, nil)
}
}
// Action with Codable Input and completion with Codable Output and Error
func mainCompletionCodableNoInput(completion: @escaping (Output?, Error?) ->
Void) -> Void {
let output = Output(count: 0)
completion(output, nil)
}
// Async throwing Action with Codable Output
func mainCodableAsyncThrowsNoInput() async throws -> Output? {
try await Task.sleep(nanoseconds: 1_000_000_000)
return Output(count: 0)
}
// Async throwing Action with a Codable Input and a Codable Output
func mainCodableAsyncThrows(input: Input) async throws -> Output? {
try await Task.sleep(nanoseconds: 1_000_000_000)
if let name = input.name {
return Output(count: name.count)
} else {
return Output(count: 0)
}
}
```
