Can Swift enums have multiple raw values?


Can Swift enums have multiple raw values?

it should still fix some issue No, an enum cannot have multiple raw values - it has to be a single value, implementing the Equatable protocol, and be literal-convertible as described in the documentation.
I think the best approach in your case is to use the error code as raw value, and a property backed by a prepopulated static dictionary with the error code as key and the text as value.

I think the issue was by ths following , As of Swift 4.2 just add Equatable protocol conformance. It will be implemented automatically.
code :
enum ExampleEquatableEnum: Equatable {
    case case1
    case case2(Int)
    case case3(String)
}

print("ExampleEquatableEnum.case2(2) == ExampleEquatableEnum.case2(2) is \(ExampleEquatableEnum.case2(2) == ExampleEquatableEnum.case2(2))")
print("ExampleEquatableEnum.case2(1) == ExampleEquatableEnum.case2(2) is \(ExampleEquatableEnum.case2(1) == ExampleEquatableEnum.case2(2))")

hope this fix your issue I'm guessing you've got an answer to this by now but just in case you didn't try this:
code :
enum AccountForm : String {
    case profile

    enum Content: String {
        static let rawValue = "Content"

        case feedback = "Feedback"
        case likes = "Likes"
    }

    enum Actions : String {
        static let rawValue = "Actions"

        case redeem = "Redeem"
        case help = "Help"
    }
}

I wish this help you I am having trouble figuring out the syntax for accessing the raw value of an enum. The code below should clarify what I am trying to do. , You can make it without switch like this:
code :
if case .Success(let str) = goodResult {
    a = str
}

may help you . If all you're trying to do is set up a correspondence between numbers and strings:
code :
0 -> Open
1 -> Closed
let arr = ["Open", "Closed"]
return arr[rawValue: section]

Hope that helps You can make your enum conform to CaseIterable, then simply iterate through allCases to create typeDescription.
code :
enum MyEnum: CaseIterable {
    case caseA(data: [Int])
    case caseB(data: [String])
    case caseC(data: [Date])
    case caseD(data: [Data])

    static var allCases: [MyEnum] = [.caseA(data: []), .caseB(data: []), .caseC(data: []), .caseD(data: [])]

    var caseDescription: String {
        switch self {
        case .caseA:
            return "caseA"
        case .caseB:
            return "caseB"
        case .caseC:
            return "caseC"
        case .caseD:
            return "caseD"
        }
    }

    static var typeDescription: String {
        return allCases.map {$0.caseDescription}.joined(separator: ", ")
    }
}
