I could define a function like this
func doWithAction(action: ()-> void) {
// something
}
However, when I use the function, the auto-completion of Xcode give me a block/closure
self.addPullToRefreshControllerWithAction { () -> void in
}
I know closure and function are something same in Swift, but I want to lead the one who use this function to pass a function in, not a block. The reason why I do this is I want this function to behave like a selector and a delegation
yes, closure and functions are practically the same in swift, so if the function expects a closure, you can pass a function with the same signature as a parameter instead. like this
func iAmAFunc(() -> Void) -> Void {
//do stuff
}
func funcThatTakesVoidAndReturnsVoid() -> Void {
//do stuff
}
var closureThatTakesVoidAndReturnsVoid: () -> Void = { }
iAmAFunc(funcThatTakesVoidAndReturnsVoid)
iAmAFunc(closureThatTakesVoidAndReturnsVoid)
