Updated to Xcode 7.1 (from 6.4) caused UIIMageView animation broken

Question

I upgraded my Xcode project that has been compiling just fine in 6.4 and choose not to upgrade to Swift 2.0 (I want to get it to compile first before causing more errors).

I got hundreds of errors, most have been fixed now, but I can't figure this one out. This has been working in 6.4:

var imgListArray:NSMutableArray = []
self.imageView.animationImages = imgListArray as [AnyObject]

I get the error in 7.1.1:

'NSMutableArray' is not implicitly convertible to '[AnyObject]'; did you mean to use 'as' to explicitly convert?

If I try the compilers suggestion I get this:

self.imageView.animationImages = imgListArray as [AnyObject] as [AnyObject]

That gives me the error:

Cannot assign value of type '[AnyObject]' to type '[UIImage]?'

Answer 1

What you have to do is declare imgListArray as array of images. Here is how to do that:

var imgListArray: [UIImage] = []
self.imageView.animationImages = imgListArray

Answer 2

Here's how I fixed your error:

   var imgListArray = [AnyObject]()
        self.imageView.animationImages = imgListArray as! [UIImage]
