Swift 3.0+

var string = "hello Swift"if string.range(of:"Swift") != nil { 
    print("exists")
}// alternative: not case sensitive
if string.lowercased().range(of:"swift") != nil {
    print("exists")
}

Older Swift

var string = "hello Swift"if string.rangeOfString("Swift") != nil{ 
    println("exists")
}// alternative: not case sensitive
if string.lowercaseString.rangeOfString("swift") != nil {
    println("exists")
}
