Check wheter one string contains other or not in swift?

Question

I have a two strings. I want to check if the letters of the 2nd string are a part of the first or not in swift? How to do it?

Do you wish to check that one string contains another entirely? For example, "ABC DEF" contains substring "C D" — Alexander, Dec 28 '16 at 16:19
What exactly are you looking for? Should the second string be a *substring* of the first, or can the letters of the second string be contained in the first string *in any order?* Please clarify the question, perhaps with concrete examples of what you are trying to achieve. — Martin R, Dec 28 '16 at 16:29

Simplest way:

let string = "Some string"

if string.range(of: "Some") != nil {
    //do what you need
}

And if you need case insensitive check:

if string.lowercased().range(of: "some") != nil {
    //do what you need
}

let str1 = "Aman"
let str2 = "an"
str1.contains(str2) //returns true.

Hope this helps.
