Here you go:

if emailString.rangeOfString("@") != nil{
    println("@ exists")
}

You can use this

if emailString.rangeOfString("@") == nil {
        println("Email must contain at sign.")
}

You can use a standalone find

function like:

let s = "hello"
if (find(s, "x") != nil) {
    println("Found X")
}
if (find(s, "l") != nil) {
    println("Found L")
}
