@roopeshchander How does that work if I'm using "string" multiple times throughout the rest of the method?

@mjtsai We can't avoid the extra indentation because `if` is unavoidable, right?

@roopeshchander Right. That's why I think there needs to be a better way to do this in Swift.

@roopeshchander My main issue is that there's going to be 3+ lines of error-handling code for each line that does something that might fail. -
@mjtsai Stepping back, I think it's weird that an NSString's init() can fail. Ideally, there would only be a class method in Swift, I think. - View other replies

@mjtsai Because, unlike Obj-C, Swift init() doesn't return the self object. -
@roopeshchander Yeah. Will be interesting to see how this evolves in Swift. Not sure I like the current way of wrapping in class methods. -
@mjtsai Beta 4: "Swift does not support object initializers that fail by returning null." (Workaround: factory method.) - View other replies

@roopeshchander I think that’s what it said in precious versions, too. Hope they come up with something.
