Usage

The scale logic itself is available in the generic Size type, which works with (width, height) tuples of any FloatingPoint type. So this can be used by any code, no matter the actual type of the size or rectangle:

let scaledSize = Size.scaledToFit(orinigalSize: (10, 15), size: (20, 30))

There is also a convenience extension for the CGSize type, which is available for all of Apple's platform SDKs:

let originalSize = CGSize(width: 10, height: 15)
let containerSize = CGSize(width: 20, height: 30)
let scaledSize = originalSize.scaledToFit(size: containerSize)

If you want to only scale down, use scaledDownToFit:

let scaledSize = originalSize.scaledDownToFit(maxSize: containerSize)

The new size will be a smaller version of the original size. If the original size completely fits into the provided container size, the function will return nil, indicating that no scaling is necessary. You can fall back to the original size in that case:

let scaledSize = originalSize.scaledDownToFit(maxSize: containerSize) ?? originalSize

Similarly, if you want to only scale up, use scaledUpToFit. The new size will be a larger version of the original size, or nil if no scaling is needed.
