RealmableEnum not able to determine RawValue

[DantePuglisi]

I'm having a crash that reads:

*** Terminating app due to uncaught exception 'RLMException', reason: 'Property 'enumType' is declared as 'MyEnum', which is not a supported RLMObject property type. All properties must be primitives, NSString, NSDate, NSData, NSNumber, RLMArray, RLMSet, RLMDictionary, RLMLinkingObjects, RLMDecimal128, RLMObjectId, or subclasses of RLMObject. See https://realm.io/docs/objc/latest/api/Classes/RLMObject.html for more information.'

I suspect it's because I have this init in MyEnum which I can't change (because it's used in other targets I don't have access to). What could be the cause? I spent some time trying to determine the issue and discovered that inside the Realm framework on (BOOL)setTypeFromRawType:(NSString *)rawType in RLMProperty rawType is @\MyEnum\ which is wrong because all others are some variation of ObjC primitive types.

Here's my enum code:

public enum MyEnum: String, RealmableEnum {
    case blue
    case red
    case unknown
    
    // MARK: - Initialization
    
    public init(rawValue: String) {
        let lowercased: String = rawValue.lowercased()
        switch lowercased {
            case Self.red.rawValue: self = .red
            case Self.blue.rawValue: self = .blue
            default: self = .unknown
        }
    }
}
