Cannot seem to use CGRectIntegral and CGRectInset functions in Swift

Question

Sorry for the novice question.

But just as the title says, I can\'t seem to use these functions in Swift 3. I have tried by importing the CoreGraphics library, but to

Answer 1

The functions are working fine, but their names have changed (a bit):

  let frame = CGRect.zero
  let x = frame.integral
  frame.insetBy(dx: 0, dy: 0)

Answer 2

1. import CoreGraphics

2. let rect = CGRect() let rectIntegral = rect.integral

Thanks:)

Answer 3

Actually you don't need to import CoreGraphics.

In Swift 3 Objective-C function

CGRect CGRectIntegral(CGRect rect)

has become

var integral: CGRect { get }

and

CGRect CGRectInset(CGRect rect, CGFloat dx, CGFloat dy);

has become

func insetBy(dx: CGFloat, dy: CGFloat) -> CGRect

Both API have to be called on the CGRect instance for example

let newFrame = view.frame.insetBy(dx: 10.0, dy:10.0)

A hint to find out yourself

• Press ⇧⌘0
• Type CGRectIn in the search field
• In the popup menu set the language to Objective C
• Select one of the functions
• Set the language to Swift
