# Return a function from a function

When you want a function to return a `String`, it's pretty obvious:
```
func whatIsForLunch() -> String {
    return "Something delicious"
}
```

If you want to return a function, then the return type looks more like this: `() -> Void`.
The key bits that trip me up: 
* You need `{ }` to assign the function to a variable or constant.
* You need `()` to use the assigned function

```
func howToMakeACake() -> (() -> Void) {
   // return some function
}

var cakeRecipe: () -> Void 
cakeRecipe = { howToMakeACake() }  // you need the { }

if timeForCake {
    cakeRecipe()  // you need the () to run the function
}
```
