Summary:
I'm creating a convenience init method to generate resizable images, however it is not possible to do this in Swift.

For example, if my init method looks like:

init(…) {
  // …
  self.init(CGImage: someImage)
  //
  return self.resizableImageWithCapInsets(…)
}

This errors, because you cannot return non-nil. However, UIImage has no facility to adjust the cap insets in-place, because it's an immutable object.

Steps to Reproduce:
1. Attempt to create a convenience init method to generate resizable images
2. Fail because UIImage is not able to do so

Expected Results:
UIImage as an init method which can set the cap insets so I don't have to create another instance for it

Actual Results:
UIImage can only return a resizable image based on another image, which does not mesh well with Swift

Version:
Xcode 7.0.1
