I want to replace some text in a string with another string.
For example : A string equals to "Red small car". I want to replace "small" with "big" so the string becomes "Red big car". I have to do this in swift. Thanks.

You can try using stringByReplacingOccurrencesOfString
let string = "Big red car"
let replaced = (string as NSString).stringByReplacingOccurrencesOfString("Big", withString: "Small")
Edit In Swift 5
import Foundation
let string = "Big red car"
let replaced = string.replacingOccurrences(of: "Big", with: "Small")

This gives me an error in REPL:
error: cannot invoke 'stringByReplacingOccurrencesOfString' with an argument list of type '(StringLiteralConvertible, withString: StringLiteralConvertible)', w.o. the cast, it works.

@SebastianDressler: Which Xcode version are you using? That code compiles and works fine (as well as yours) in Xcode 6.1.1. Of course, using NSString in the REPL requires that you
import Foundation. – Anyway, this question has already been asked and answered (probably more than once).Sebastian
@MartinR it is 6.1.1 and I imported
Foundation. Very strange...

For Swift 3, you will want to use
let replaced = string.replacingOccurrences(of:"Big" with "Small")
Richter
@AlexShaffer the comma should be added before "with", also colon be added after "with":
let replaced = string.replacingOccurrences(of:"Big", with:"Small") |
You can use stringByReplacingOccurrencesOfString, e.g.
let s1 : String = "Red small car"
let s2 = s1.stringByReplacingOccurrencesOfString("small", withString: "big")
