Swift 2.0: Type of Expression is ambiguous without more context?

Question

The following used to work in Swift 1.2:

var recordSettings = [
    AVFormatIDKey: kAudioFormatMPEG4AAC,
    AVEncoderAudioQualityKey : AVAudioQuality.Max.ra         


        

Answer 1

I also got this error message trying to initialise an array of optionals with nil:

var eggs : [Egg] = Array(count: 10, repeatedValue: nil)

Expression Type 'Array' is ambiguous without more context.

Changing [Egg] to [Egg?] fixed the error.
