How do you access a variable outside a function in swift -

i trying access inputac , inputb outside function getvariables , can't seem working.

here code working work.

func getvariables () { var inputac = textfieldac.text.toint() var inputb = textfieldb.text.toint() } var ac = inputac var b = inputb

anyone have ideas?

thanks

you need homecoming values function. here 1 way returning them in tuple:

func getvariables () -> (int?, int?) { var inputac = textfieldac.text.toint() var inputb = textfieldb.text.toint() homecoming (inputac, inputb) } var (ac, b) = getvariables() // since values optionals, can utilize optional binding // safely disclose value. if allow acval = ac { println("ac value \(acval)") } else { println("alas, ac nil") }

function variables swift
