'init()' is deprecated: init() will be removed in Swift 3. Use `nil`

Question

I was using this code.

var audioUnit:AudioUnit = AudioUnit()

But in Xcode 7.3 (Swift 2.2) I am getting this warning. Any idea why? And how can I get rid of that?

N.B. Is I use nil then my program crashes.

Answer 1

AudioUnit is a typealias of AudioComponentInstance which itself is a typealias of COpaquePointer. Initializing pointers will be removed with Swift 3.0, just set the variable to nil.

nil and AudioUnit() should do the same thing. If your program is crashing with nil, you probably have a bug somewhere else.
