How do I check if a string contains another string in Swift?
...ng is a collection of Character values, it wasn't like this in Swift 2 and 3, so you can use this more concise code1:
let string = "hello Swift"
if string.contains("Swift") {
print("exists")
}

var string = "hello Swift"
if string.range(of:"Swift") != nil {
print("exists")
}
