Swift: Getting a string width to make a frame (using CGRect) in swift 2.2

How can I get width of a string in swift 2.2 and iOS 9 ?
What I want to do is to create a UIButton programmatically but its frame needs to fit the title size which will be inferred at runtime.
Note: We know frame's height.

You might want to use the NSString method boundingRectWithSize:options:attributes:context:.

e.g.:

let rectNeeded = aString.boundingRectWithSize(CGSize(width: yourWidth, height: yourHeight), options: .UsesLineFragmentOrigin, attributes: [NSFontAttributeName: aFont!], context: nil)

Note that you need to cast you String into an NSString before being able to use this method.

Don't use frames. Use auto layout. If you use auto layout to place this button into the interface, it will be sized to fit its text automatically.

You can get the size by declaring your button title text as NSString. Try this:

let title: NSString = "some title"
let size = title.sizeWithAttributes([NSFontAttributeName: UIFont.systemFontOfSize(20.0)]) //you can add NSForegroundColorAttributeName as well

After you have set the text of button just call :-

yourButton.sizeToFit()
