Swift returns 'UInt32' is not convertible to 'CGImage'

I got this error message based on code below:

Error message

/Users/MNurdin/Documents/iOS/XXXXX/HAHA.swift:534:38: 'UInt32' is not convertible to 'CGImage'

My code

let context : CGContextRef = CGBitmapContextCreate(nil, CGImageGetWidth(image.CGImage), CGImageGetHeight(image.CGImage),
                CGImageGetBitsPerComponent(image.CGImage),
                CGImageGetBytesPerRow(image.CGImage),
                CGImageGetColorSpace(image.CGImage),
                CGImageGetBitmapInfo(UInt32(image.CGImage)).rawValue)!;

            CGContextConcatCTM(context, transform);

Raw value is returning UInt32 so try:

CGImageGetBitmapInfo(image.CGImage).rawValue

As the error states you are passing a UInt32 to a function which expects a CGImage.

CGImageGetBitmapInfo expects a CGImage as it's argument and returns CGBitmapInfo

You are probably looking for:

UInt32(CGImageGetBitmapInfo(image.CGImage).rawValue)

It's exactly as the error states, you can't convert a number to a CGImage

I'm not sure why you're trying to convert a CGImage into a UInt32 before passing it into CGImageGetBitmapInfo. Just pass the CGImage in directly.

CGImageGetBitmapInfo(image.CGImage);
