Getting error while accessing internal enum from public enum in swift 4.2

Question

I am getting error while accessing internal enum values inside public enum

Code snippet

@objc public enum Sample1 : Int {
      case valid
      fileprivate static var upgradeStatus:[String: Sample1] = [
          RawString.validValue.rawValue : .valid
      ]
}

internal enum RawString: String {
    case validValue = "Invalid"
}

The error says

Enum 'RawString' is internal and cannot be referenced from a property initializer in a '@_fixed_layout' type

Looks like it is because of bridging @Objc but not able to fix the issue. I cannot remove @Objc as my code is used in Objective C project as well.

Could anyone please help me in resolving this issue.

P.S : Started observing this error once after I update to Xcode 10

You could convert upgradeStatus to a static method, this will make your code compile:

fileprivate static func upgradeStatus() -> [String: Sample1] {
    return [
        RawString.validValue.rawValue : .valid
    ]
}
