Call can throw, but errors can not be thrown out of a global variable initializer

Question

I\'m using Xcode 7 beta and after migrating to Swift 2 I experienced some issues with this line of code:

let recorder = AVAudioRecorder(URL: soundFileURL, settin         


        

Answer 1

If you know that your function call will not throw an exception, you can call the throwing function with try! to disable error propagation. Note that this will throw a runtime exception if an error is actually thrown.

let recorder = try! AVAudioRecorder(URL: soundFileURL, settings: recordSettings as! [String : AnyObject])
