cgImageSource infinite recursive loop

[andwaredev-zz]

Hi and thank you so much for the amazing work you've done developing this project.

I've encountered a bug that I'm not sure how to resolve.

I'm hitting the line let imgCount = CGImageSourceGetCount(cgImageSource)
inside private class func isCGImageSourceContainAnimatedGIF(cgImageSource: CGImageSource!) -> Bool
and I'm encountering an error that crashes my app.

warning: could not load any Objective-C class information. This will significantly reduce the quality of type information available.

By using print(cgImageSource) I can see an infinite list of different memory locations printed out until the crash occurs. Short example:
cgImageSource : <CGImageSource 0x145bac450 [0x1a0493150]> cgImageSource : <CGImageSource 0x145cd1630 [0x1a0493150]> cgImageSource : <CGImageSource 0x145bb4c80 [0x1a0493150]> cgImageSource : <CGImageSource 0x145ce0440 [0x1a0493150]> cgImageSource : <CGImageSource 0x145bb2150 [0x1a0493150]> cgImageSource : <CGImageSource 0x145ce0610 [0x1a0493150]>

Any guidance would be greatly appreciated.
