After working with Swift for some time I found there are lot of things that aren’t there out of the box as with other languages. Following are some extensions that I think are useful for day to day working

Accessing string element by index

extension String {
    subscript(i:Int) ->Character {
        let index = self.index(self.startIndex, offsetBy: i)
        return self[index]
    }
}
