How can I find the index of an item in Swift? [duplicate]

Answer 1

You can add an Array Extension that does exactly what you want, i.e:

extension Array {
    func indexOf(x:T) -> Int? {
        for i in 0..self.count {
            if self[i] as T == x {
                return i
            }
        }
        return nil
    }
}

Which now lets you use .indexOf() on all Swift arrays, e.g:

["Jason", "Charles", "David"].indexOf("Jason")  //0
