You can check if an enum case exists within an array in Swift using the contains() method. Here's how you can do it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
enum MyEnum {
case case1
case case2
case case3
}
let myArray: [MyEnum] = [.case1, .case3]
if myArray.contains(.case2) {
print("Enum case .case2 exists in the array.")
} else {
print("Enum case .case2 does not exist in the array.")
}
|
This will output:
1
|
Enum case .case2 does not exist in the array. |
You simply call the contains() method on the array and pass in the enum case you want to check for. If the case exists in the array, it returns true; otherwise, it returns false.
