Swift • 枚举可以有多个案例吗？

Question

I am working on a Swift App which uses an Enum . However, this Enum will have a bunch of cases. Maybe 1,000 or even more.

Code

enum Name: Int, CaseIterable {
    case name1
    case name2
    case name3
    // Many more...
    
    var string: String {
        switch self {
            case name1: return "Name 1"
            case name2: return "Name 2"
            case name3: return "Name 3"
            // Many more...
        }
    }
}

Question: Will an Enum with more than 1,000 Cases work? Or will there be a problem? Which other Data Structure is the best fit in this case?

Question 2: the Enum has also computed Properties with Switch-Statements in it. Is there any Problem with Switch-Statements with over 1,000 Cases?

Thanks a lot for your help!

Answer 1

You can try something like this -

1. Store the known list of valid names in a json resource file.
2. Add a failable initializer on your data model that validates the name value against this known list of names from that json. If you provide an invalid name value (that's not known in names json) - init will fail and your data model will not be instantiated.
3. Data model's name property is still a String - not an enum case.
