What are the differences between #if, @available, and if #available, in terms of both compilation and use case? Here is my understanding so far: If I want to make a function available on macOS only, I can do it like t In contrast with condition compilation statements in the C preprocessor, conditional compilation statements in Swift must completely surround blocks of code that are self-contained and Availability checking in Swift gives us the ability to ask whether the user is running a specific or newer version of an operating system, and run code only if that test passes.
