Introduction
I have used Swift for windows 1.9 for debugging purpose. But you can use any Swift programming language compiler as per your availability.
func checknumbers(_ a: [Int]) -> Bool { if a.contains(4) || a.contains(8) { return true } else { return false } } print(checknumbers([2, 6, 7])) print(checknumbers([4, 8])) print(checknumbers([4, 8, 5]))
Result
![Write a Swift program to test if an array of integers contains a 4 or a 8](https://techstudys.com/wp-content/uploads/2021/07/11-12.png)
