[swift-evolution] Remove default case in switch-case

[Mustafa Yusuf]

Hello all. In switch statements in swift if all the possible cases aren't covered we have to supply a default case.



    let number = 10



    switch number {

    case 10: print("yay")

    case 12: print("close")

    default: print("try again")
    }



My proposal is replace it with the "case _:".



    let number = 10



    switch number {

    case 10: print("yay")

    case 12: print("close")

    case _: print("try again")

    }



Since underscore in swift means "whatever I don't care" it suits here better than "default". Correct me If I am wrong but this is the only use for "default" keyword in swift I guess. So we can completely remove "default" keyword from the language.
