Xcode 13.2 Beta Release Notes

iOS 15.2 beta introduces App Privacy report which shows what app does with user data, which hosts it interacts with.

iOS 15 and iPadOS 15 introduced the Record App Activity feature in the privacy settings, allowing people to save a summary of sensor, data, and internet access by apps on their device.

In iOS 15.2 beta and iPadOS 15.2 Beta, this activity is presented in Settings in a new UI called App Privacy Report. This is a great opportunity to review your app’s sensor, data, and internet usage. To view your activity in the report, go to Settings > Privacy > App Privacy Report > Turn On App Privacy Report. Activity will show once you use your app. (78696668)
