Crash by accessing enum field after deserialising snapshot

[hiroshitazawa]

I have a query with the following GraphQLEnumType.

enum FeatureClass {
    person
    car
    cat
    dog
  }

When I run apollo-codegen, I get the following enum definition and it works fine.

public enum FeatureClass: String, Apollo.JSONDecodable, Apollo.JSONEncodable {
  case person = "person"
  case car = "car"
  case cat = "cat"
  case dog = "dog"
}

public var classes: [FeatureClass] {
  get {
    return snapshot["classes"]! as! [FeatureClass]
  }
  set {
    snapshot.updateValue(newValue, forKey: "classes")
  }
}

However, I serialise the snapshot data using JSONSerializationFormat, save it in NSUserDefault, deserialise it and access the field of the enum again, I get the following crash.

someData.classes (Crash)

Could not cast value of type 'NSTaggedPointerString' (0x110dde5c8) to 'XXX.FeatureClass' (0x106d48600)

I personally investigated the issue of this field by accessing through snapshot dictinary and found that casting the certain enum type is making the crash.

po someData.snapshot["classes"]! as! [FeatureClass] (Crash)

However, if I access the enum field as the array of enum.rawValue, it works fine.

po someData.snapshot["classes"]! as! [FeatureClass.RawValue] (Works)

Is this the expected behaviour ?.
I am using apollo-codegen 0.17.1 (not latest). I can't use the latest apollo-codegen for some enum naming issues.

Thanks in advance.

I just found the solution about this issue. It was related to this previous post. #51

If I construct the deserialised dictionary with Something.Data(jsonObject:), then, it works fine.
I close this issue post.
