UnsafeMutablePointer in structs


(Adrian Zubarev) #1

Can I put an UnsafeMutablePointer inside a struct and destroy deallocate correctly without nesting a class which has `deinit`? I’m not sure how to check this.

No, you’ll have to wrap it in a class. That said, class references from a struct are frowned upon, as you may wind up sharing mutable state (which structs are meant to combat).

What’re you trying to represent with the UnsafeMutablePointer? A connection handle?

Thank you, actually I only was curious what will happen if I do because I couldn’t think of a way to check what will happen to the pointer. Lets see how the core team re-build Foundation types like NSData to Data struct.
