Suggested approach: There are a few ways you could tackle this, but I would recommend either talking about the
&& operator or the
assert() function – something you use regularly, and so feel comfortable talking about in detail.
First, start with a simple definition:
@autoclosure silently turns a function’s parameter into a closure so that it can be executed on demand rather than immediately. Now, pick a specific example such as
assert() and explain why it’s used – the autoclosure behavior here ensures our assertion doesn’t happen in release mode, so it won’t have a performance impact when we ship apps to the App Store.
