CGSize(width: 360, height: 480) and CGSizeMake(360, 480) seem to have the same effect. Is one preferred to the other? What is the difference?

Overview. A CGSize structure is sometimes used to represent a distance vector, rather than a physical size. As a vector, its values can be negative. To normalize a CGRect structure so that its size is represented by positive values, call the CGRectStandardize(_:) function.
A structure that contains the location and dimensions of a rectangle.
The CGSize constructor is a Swift extension on CGSize:
extension CGSize {
public static var zero: CGSize { get }
public init(width: Int, height: Int)
public init(width: Double, height: Double)
}
CGSizeMake is a leftover inline function bridged from Objective-C:
/*** Definitions of inline functions. ***/
// ...
public func CGSizeMake(width: CGFloat, _ height: CGFloat) -> CGSize
Both have the same functionality in Swift, the CGSize constructor is just more "Swifty" than the other and provided as a convenience.

While as functionality they don't have any difference, CGSizeMake() is/will be deprecated. It is easier to write and read CGSize(), so Apple prefers you to use CGSize() for the future.
