Objective C signature to Swift

[Wimpie Pieterse]

Good Day,

I am struggling to convert this method signature to Swift:

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{...

Can someone please help?

[Adam Sharp]

This should work:

    func image(image: UIImage, didFinishSavingWithError error: NSErrorPointer, contextInfo: UnsafePointer<()>)

And alternatively this should be equivalent to NSErrorPointer:

    inout didFinishSavingWithError error: NSError

HTH

func image(image: UIImage,
didFinishSavingWithError: NSErrorPointer,
contextInfo: UnsafePointer<()>) {
// ...
}


I think. Void is represented as an empty tuple () so a void *
is an UnsafePointer<()>. Again, I think :)
