CALayer's contentsCenter not working in swift
I want to increase an image button's touch area, and as I searched, I found a way to use contentsCenter property of CALayer.
https://developer.apple.com/documentation/quartzcore/calayer/1410740-contentscenter
The example of the document above shows an image centered inside the layer that can be resized as the size of layer changes, while maintaining the ratio defined in contentsCenter property.
But when I used contentsCenter property, it just stretches the image's center - (0.5, 0.5).
So I added contentsGravity property to .center, but it results in contentsCenter property not working.
button.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
button.center = view.center
button.backgroundColor = .clear
let image = UIImage(named: "profileImage")
button.layer.contents = image?.cgImage
button.layer.contentsCenter = CGRect(x: 0.25, y: 0.25, width: 0.5, height: 0.5)
button.layer.contentsGravity = .center
//button.layer.contentsScale = image?.scale
button.layer.borderColor = UIColor.black.cgColor
button.layer.borderWidth = 2
button.layer.cornerRadius = 5
button.layer.masksToBounds = true
How can I make the image center inside a button with insets maintaining ratio?

Well, the whole premise of the question is false. ThecontentsCenterproperty has nothing whatever to do with how to "increase an image button's touch area". So this is what we call an x-y question: you've assumed a false solution to your real problem, and now you're asking why the false solution is false rather than asking about the real problem. I suggest you back this question out and ask instead about how to "increase an image button's touch area".

You can increase the UIButton Size using the below Code
button.contentEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
