How to use ManagedAppDistribution Framework

Hi I have tried the code given on link https://developer.apple.com/documentation/appdistribution/fetching-and-displaying-managed-apps. This code is not compilable in Xcode 16.1. After some fixes i am able to run the code but i am getting Error registering for message: [App catalog changed]: An unspecified, unrecoverable error occurred.

Kindly help me with this.

Please make sure you have the entitlement for Managed App Installation UI.
