Summary:
In Swift2.0, Int/UInt type can be AnyObject. But Int32/UInt32 cannot be AnyObject. I think these fixed size types should also be 'AnyObject'.
Because, we have to write many cast code as follows:
let output = AVAssetReaderTrackOutput(track: compoVideoTrack,
outputSettings: [String(kCVPixelBufferPixelFormatTypeKey) : NSNumber(unsignedInt:kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange),
String(kCVPixelBufferIOSurfacePropertiesKey) : [:] as NSDictionary])
Most of codes using AVFoundation are similar with above 'castful' & ugly code. AVF uses OSType(is typealias to UInt32) anywhere.
Steps to Reproduce:
// 1
let uValue: UInt = 10
let foo: AnyObject = uValue
// 2
let u32Value: UInt32 = 10
let bar: AnyObject = u32Value
Expected Results:
We can compile both 1 & 2.
Actual Results:
Only 1 is compiled. 2 become compile error.
