Disabling pointers in Swift -

how can value of variable variable without them having same pointer? is, in code below, keepscale value getting updated 1 when after recognizer.rotation set 1.

code

var keepscale : cgfloat = 1  func handlepinch(recognizer : uipinchgesturerecognizer) {         if let view = recognizer.view {             view.transform = cgaffinetransformscale(view.transform,                 recognizer.scale, recognizer.scale)              keepscale = recognizer.scale             println(keepscale)              recognizer.scale = 1             println(keepscale)          }     } 

example logs

0.5

1.0

ok since scale ratio had multiply keepscale value recognizer.scale , not set equal.
