This Swift code contains one error – can you select the line that is incorrect?
Tip: You should mentally run the code from top to bottom, meaning that if line 3 says an integer should be returned and line 10 tries to return a string, line 10 is the wrong one.
func verifyUser(identifier: Int) -> string {
var str: String = "Found "
switch identifier {
case 0:
str += "TwoStraws"
case 1:
str += "Taylor"
default:
str += "nothing for ID \(identifier)"
}
return str
}
print(verifyUser(identifier: 1))
