I get this red warning in Xcode every time my app is syncing to the iCloud. My model has only basic types and enum that conform to Codable so i'm not sure what is the problem. App is working well, synchronization works. But the warning doesn't look good. Maybe someone has idea how to debug it.

Hello! Its hard to believe that this is Apple. I use iPhone since iPhone 3G, I use MacBook, iPad and Apple Watch. I am normal - you could say faithful user os Apple. I applied to Enroll in Apple Developer Program and I got error - „Your enrollment in the Apple Developer Program is under review. Please contact us.” Of course I did contact Apple by email. I got the response: „For one or more reasons, your enrollment in the Apple Developer Program could not be completed. We are unable to continue with your enrollment at this time. „ That is already very frustrating but it gets better! Few days later I decided to call them. Apple advisor checked my case and after few minutes told me exactly the same thing - „for one or more reasons…” I am already very surprised and shocked - so I ask what can I do? Answer - nothing. I asked to escalate my case, I am normal user, I provided my ID and everything, why can’t I enroll? After about 20 minutes I got email: „For one or more reasons, your enrollment in the Apple Developer Program could not be completed. We are unable to continue with your enrollment at this time. (…) I understand you’re not satisfied with this outcome, but please note we cannot provide you with the reasons and this decision is final.” Is it normal? I am from Poland - normal European country. I am not criminal, I work, I use apple devices and I learned programming. But Apple just basically told me that they don’t care.
