If you want to use them as in swift 2  you can use these funcs   For CGRectMake   func CGRectMake   x  CGFloat    y  CGFloat    width  CGFloat    height  CGFloat  - gt  CGRect       return CGRect x  x  y  y  width  width  height  height      For CGPointMake   func CGPointMake   x  CGFloat    y  CGFloat  - gt  CGPoint       return CGPoint x  x  y  y      For CGSizeMake   func CGSizeMake   width  CGFloat    height  CGFloat  - gt  CGSize       return CGSize width  width  height  height      Just put them outside any class and it should work   Works for me at least

CGRect Can be simply created using an instance of a CGPoint or CGSize  thats given below   let rect   CGRect origin  CGPoint x  0 y  0   size  CGSize width  100  height  100         Or  let rect   CGRect origin   zero  size  CGSize width  100  height  100     Or if we want to specify each value in CGFloat or Double or Int  we can use this method   let rect   CGRect x  0  y  0  width  100  height  100     CGFloat  Double  Int   CGPoint Can be created like this    let point   CGPoint x  0 y  0     CGFloat  Double  Int   CGSize Can be created like this   let size   CGSize width  100  height  100     CGFloat  Double  Int   Also size and point with 0 as the values  it can be done like this   let size   CGSize zero    width   0  height   0 let point   CGPoint zero    x   0  y   0  equal to CGPointZero let rect   CGRect zero    equal to CGRectZero   CGRectZero  amp  CGPointZero replaced with CGRect zero  amp  CGPoint zero in Swift 3 0
