TupleResult
A micro library that easily converts c-style tuple result into Swift.Result
In some cases, the result of the completion handler is returned in the form of response and error tuple. In Swift5 and later, Swift.Result makes writing code more intuitive. Using TupleResult, you can easily change the tuple result type to Swift.Result type.
Completion handler with response and error tuple
// Example
public func executeMethod(completion: (Response?, Error?) -> Void) {
// when failure
completion((nil, myError))
// when success
completion((myResponse, nil))
}
🧐
Before
import OtherModule
executeMethod { response, error in
if let error = error {
// handle failure
return
}
guard let response = response else { return }
// handle success
}
🚀
After
import TupleResult
import OtherModule
executeMethod {
switch Result(success: $0, failure: $1) {
case .success:
// handle success(let success):
case .failure(let failure):
// handle failure
}
}
