Write a Swift program to test if a given string starts with “test”

import Foundation
 
func checkstring(_ input: String) -> Bool {
    if input.hasPrefix("test")
    {
        return true
    } 
    else 
    {
        return false
    }
}
print(checkstring("testpqrsab"))
print(checkstring("testabpqrsab"))
print(checkstring("pqrs"))
print(checkstring("abpqrs"))

Output:
