@mjtsai Just saw that. On second thoughts, it's better NOT to use implicit unwrapping here, coz we need to check for nil. if-let is better.

@roopeshchander Choice between compiler help with safety and avoiding extra indentation.

@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.

@mjtsai @mjtsai I don't think an `if` block by itself makes it bad-looking code.

@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.

@mjtsai Because, unlike Obj-C, Swift init() doesn't return the self object.
