For performance, CoreGraphics types (like CGAffineTransform) were made to be C structs rather than Objective C classes. C structs can't contain methods, constructors, etc. To simulate this, raw functions were made like CGAffineTransformMakeRotation to perform operations on these structs.

Swift supports struct methods, so in Swift, these raw functions are imported as methods on the CGAffineTransform struct. You're looking for CGAffineTransform(rotationAngle:)
