Hullo, I wanted to turn a class in a struct and move intelligence in a protocol extension, but when I try to call inits in the extension I get
'self' used before 'self.init' call or assignment to 'self'
How do I call self.init or assign to self before updating the values? Of course init does no accept mutating.

Why?
There's a lot of pressure for developers to use static typing practices like using structs instead of classes. But a dirty little secret is that Swift is a great object-oriented language.

You don't have self until you call init. Despite my previous statement about Swift, it does have its quirks. In object-oriented Swift, you must initialize instance values before calling super.init, which is actually backwards. (There are "reasons" for this, but rather than making those edge cases a developer responsibility, they built it into the language. Because Swift is safe by default, except when it isn't.)
But if you're writing an extension on a struct, then it's more logical. You must construct the object before you can use it.
