Update CGRectMake to CGRect in Swift 3 Automatically

Question

Now that CGRectMake , CGPointMake, CGSizeMake, etc. has been removed in Swift 3.0, is there any way to automatically update all initializations like from CGRectMake(0,0,w,h) to CGRect(x:0,y:0,width:w,height:h). Manual process is.. quite a pain.

Not sure why Apple don't auto convert this when I convert the code to Current Swift Syntax...

Answer 1

The simplest solution is probably just to redefine the functions Apple took away. Example:

func CGRectMake(_ x: CGFloat, _ y: CGFloat, _ width: CGFloat, _ height: CGFloat) -> CGRect {
    return CGRect(x: x, y: y, width: width, height: height)
}

Put that in your module and all calls to CGRectMake will work again.

Answer 2

Short answer: don't do it. Don't let Apple boss you around. I hate CGRect(x:y:width:height:). I've filed a bug on it. I think the initializer should be CGRect(_:_:_:_:), just like CGRectMake. I've defined an extension on CGRect that supplies it, and plop that extension into every single project the instant I start.

extension CGRect {
    init(_ x:CGFloat, _ y:CGFloat, _ w:CGFloat, _ h:CGFloat) {
        self.init(x:x, y:y, width:w, height:h)
    }
}

That way, all I have to do is change "CGRectMake" to "CGRect" everywhere, and I'm done.

Answer 3

Apple actually does provide this feature. All you have to do is go to:

Edit > Convert > To Latest Swift Syntax...

And then follow the onscreen prompts.

This will solve your syntax issues and you won't have to make new functions for all of the various removed functions.
