@roopeshchander How does that work if I'm using "string" multiple times throughout the rest of the method?
@mjtsai On your latest blog post, the recommended replacement for macros is functions, so:
MJT_ENSURE(string, e, error)?.doSomething()

@mjtsai It doesn't :). You will have to use an `if` block in that case, I admit. -
@mjtsai A minor defence: A macro with a return in it makes the code somewhat hard to read and decipher by others -
@roopeshchander Yeah, some people won't like that. I think it's worth it, and it's basically the same pattern Apple's macros have long used. -
@mjtsai I can see the value in macros like that. But I don't see a way to do that in Swift. Or rather, that doesn't fit with The Swift Way. - View other replies

@mjtsai And about the adding a `!` after each variable use, have you considered implicit unwrapping? -
@roopeshchander That's discussed in the comments. -
@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. - Show more
