Swift Completion Throws at Brayden Nail blog

Swift Completion Throws. The completion handler is the code that we get to provide to get called when it comes back with those items. In swift how do i throw an error within a completion handler like this: This is in contrast to ordinary, synchronous functions and methods, which either run to completion, throw an error, or never return. Completion closures are no longer needed, and calling into multiple asynchronous methods after each other is a lot more readable. When you first meet result it’s common to wonder why it’s useful, particularly when swift already has a perfectly good throws keyword for handling errors. To indicate that a function, method, or initializer can throw an error, you write the throws keyword in the function’s declaration after its. It’s where we can work with the.
