title: What does it mean for a function to return?
body: <p>I was reading the Apple developer documentation's definition of escaping closures. It says "a closure is said to escape a function when the closure is passed as an argument to the function, but is called after the function <strong>returns</strong>".</p>
  
  <p>I'm not sure what the last word "<strong>return</strong>" means in this context. I know a function can return values such as an Int value or a String value. But I'm not sure what it means by "after <strong>the function returns</strong>".</p>
  
  <p><strong>Please note that I'm not asking what escaping closures are</strong>. I just want to know what the word "return" means here. I asked the same question before but everyone was explaining what escaping closures are and none of them explained the word "return" so I just want to make my question clearer this time.</p>
