Same problem

Hi Quinn. First of all, I need to say that you are an Apple person that really helps. Thank you. My case its similar. I am trying try to test a game before submitting it to MAS. Especially, I am trying to test that IAP works correctly. This is a game made in Unity. I am code-signing correctly, and sandboxing the game to test authentication and then IAP. But I get several errors. I tried to identify one of them and this is the result... Apparently, when trying to access the User folder the application returns some inexistent folder within User/Library/Containers. More exactly this folder: /Users/user/Library/Containers/com.company.game And since the folder is not there, several things fail to work. I guess this happens when the Sandbox security entitlement is set. But the folder is not there, so what is necessary in order to make the OSX to create this folder?

Thank you Quinn, in my app the container folder is not being created. Do I need to add a particular Sandbox security entitlement? By user I mean my username.I should have used a different word sorry...  /Users/andres/Library/Containers/com.company.game

I have the same problem. When finally read about the Provisioning Profile, It ran fine for a couple of days. However I was having a problem (reported here https://developer.apple.com/forums/thread/107593) and decided to add a Sandbox security entitlement to the entitlements file. I guess it was the one that allows for client network access. And since then I receive the same message after login: "App" is damaged and cannot be opened. I waited a few days and left the entitlements file as it was originally (when working). But I keep getting the same message. I guess the app was blacklisted or similar. If so, how long does it last? Thank you Andres

9 months and no answer. Were you able to know if this is possible?
