Swift: get index of start of a substring in a string

Question

Is there a way to search a string for the index of the start of a substring?

Like, "hello".indexOf("el") would return 1. Thanks

Answer 1

You can reach using the rangeOfString function that finds and returns the range of the first occurrence of a given string within a given range like in the following way:

var text = "Hello Victor Sigler"

if let indexOf = text.rangeOfString("Victor")?.startIndex {
   println(indexOf) //6
}

I hope this help you.
