Swift: String contains Character?

Question:

Tag: string,swift,character

How do I check if a String includes a specific Character?

For example:

if !emailString.hasCharacter("@") {
    println("Email must contain at sign.")
}

Answer:

You can use the free-standing find function, like this:

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