Do you have a screen protector?
No, I don't. I use an iPhone and I'm an iOS developer. I don't use screen protectors, because Apple doesn't produce such accessories and discourage people from using them. Apple claims that their screens are good enough themselves.
Does it mean I'm not careful? Or, on the contrary, I "know my shit" and don't follow common madness blindly?
What is the real use for @autoclosure?
Thanks for the post Zafar! However, I think it doesn’t explain what @autoclosure really does and how it can be useful.
In your example you can pass functions directly as arguments: makeDecision(condition: true, actionTrue: action1, actionFalse: action2) without using @autoclosure.
Though, assume an action has a different set of parameters which are known beforehand: func action1(parameter: Int). Passing the function as an argument is no longer possible. What you can do is to wrap the call with a clojure: makeDecision(condition: true, actionTrue: { action1(parameter: 1) }, actionFalse: action2).
This is exactly what @autoclosure does for you automatically. Having the makeDecision function declared as in your example, you can now call it like this: makeDecision(condition: true, actionTrue: action1(parameter: 1), actionFalse: action2()), which is essentially the same as calling it like makeDecision(condition: true, actionTrue: { action1(parameter: 1) }, actionFalse: action2).
