Swift TIL 2

Following on with writing little notes to myself so I remember some key things as I learn about Swift...

I sort of feel like this will make reading code a little harder, so it's one I want to keep in mind. When calling an instance method, if it's not ambiguous, you can omit self. from the call. For example:

class Foo {
    private func inner() -> String { "Foo" }
    func outer() -> String { inner() + self.inner() }

print( Foo().outer() )

This makes me feel a little uneasy, and I strongly suspect I'll always use self. when writing such code: I'm a big fan of the idea that we write code for people, not for compilers.
