Replacement for deprecated sizeWithFont: in iOS 7?

Question

In iOS 7, sizeWithFont: is now deprecated. How do I now pass in the UIFont object into the replacement method sizeWithAttributes:?

Answer 1

As the @Ayush answer:

As you can see sizeWithFont at Apple Developer site it is deprecated so we need to use sizeWithAttributes.

Well, supposing that in 2019+ you are probably using Swift and String instead of Objective-c and NSString, here's the correct way do get the size of a String with predefined font:

let stringSize = NSString(string: label.text!).size(withAttributes: [.font : UIFont(name: "OpenSans-Regular", size: 15)!])
