Hello! I'm developing a small app for the Apple Watch and I'm using UserDefaults as a way to pass data between Interface controllers.

I ran into SIGABRT when running this code:

Code Block languagevar test: [Int] = defaults.object(forKey: "Number") as! [Int]

and this is the code that created and saved it:

Code Block languagevar oneTimeArray = Array(repeating: 0, count: 50)
let defaults = UserDefaults.standard
defaults.set([oneTimeArray], forKey: "Number")

Tou saved an array of array (with 1 element:

Code Block defaults.set([oneTimeArray], forKey: "Number")

Change with:

Code Block defaults.set(oneTimeArray, forKey: "Number")

Don't forget to close the thread if everything works OK.
