How to make enum init method public in a package?

It is publis, but seems, it is not "enough":

public enum DataToValidate {
    case object(JSONObject)
    case array(JSONArray)
    case string(String)
    case number(Double)
}

extension DataToValidate {
    public init(associatedValue: Any) {
        switch associatedValue {
        case is Int:
            self = .number(Double(associatedValue as! Double))
        case is Float:
            self = .number(Double(associatedValue as! Double))
        case is Double:
            self = .number(associatedValue as! Double)
        case is String:
            self = .string(associatedValue as! String)
        case is JSONObject:
            self = .object(associatedValue as! JSONObject)
        case is JSONArray:
            self = .array(associatedValue as! JSONArray)
        default:
            fatalError("Unrecognized type!")
        }
    }
}

when embedding, I got this:

'DataToValidate' initializer is inaccessible due to 'internal' protection level

Funny, because all the types used by DataToValidate are public.

The code looks fine although it will crash if you pass an Int to the initializer because you're force casting it to double. A better pattern would be

switch associatedValue {
  case let iVal as? Int:
    self = .number(Double(iVal))

  case let fVal as? Float:
    self = .number(Double(fVal))

  // etc...
}
