Swift arrays and contains, how to determine if a collection contains an object or value?

Question

I\'m at it again with swift arrays and containsObject provided by NSArray only!

I bridge the swift array to NSArray to do that contains:

extension Ar         


        

Answer 1

Swift 1:

let array = ["1", "2", "3"]
let contained = contains(array, "2")
println(contained ? "yes" : "no")

Swift 2, 3, 4:

let array = ["1", "2", "3"]
let contained = array.contains("2")
print(contained ? "yes" : "no")
