Understanding Swift 2.2 Selector Syntax - #selector()

Question

I am switching over the syntax of my project toward Swift 2.2 (which xCode helps me do automatically); however, I do not understand the new #selector() syntax.<

Answer 1

Swift 2.2 has deprecated Stringified selectors: In swift 2.0, we use to write the selector as a String i.e "buttonClicked". The disadvantage with this approach is that the compiler can't check whether the method really exists or not at compile time(Even if you have misspelled it).

EX:1

func buttonClicked(){
}

So the above method in the new approach can be called as #selector(buttonClicked)

EX:2

func buttonClicked(stringValue : String){
}

So the above method in the new approach can be called as #selector(buttonClicked(_:))

EX:3

func buttonClicked(stringValue : String, indexValue : Int){
}

So the above method with parameters in the new approach can be called as #selector(buttonClicked(_:indexValue:))
