@mjtsai On your latest blog post, the recommended replacement for macros is functions, so:
MJT_ENSURE(string, e, error)?.doSomething()

@mjtsai And about the adding a `!` after each variable use, have you considered implicit unwrapping?

@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. -
-
@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. - Show more
