<rdar://problem/43248387> [iOS 12] Xcode reports ~4 times higher memory usage on iOS 12 compared to iOS 11

Mobile

-

To reproduce:
1. Create an empty project or use QA attached one
2. Build it for iOS
3. Run on the device with iOS 12
4. Open Debug navigator and inspect memory usage
5. Repeat 3-4 steps with iOS 11 device (prefferably the same device but with different iOS version)

Expected results: Memory usage should be pretty much the same
Actual results: Memory usage on iOS 12 is 4 times higher than on iOS 11

Reproduced with: iPhone X iOS 12.0
Unity versions: 5.6.6f2, 2017.4.6f1, 2018.3.0a3 (latest trunk)
Xcode Version 10.0 beta (10L176w)

Note: Unity profiler and 3rd party app (GameBench) show no difference in memory usage, it's only related to XCode

Verified with latest iOS version 12.1 (16B92)

  1. Resolution Note (fix version 2018.2):

    Fixed in the latest iOS version 12.1 (16B92)

    This is specifically about the change in memory usage tracking from iOS 11 to iOS 12. For a memory consumption regression introduced by Unity in 2018.2, please see https://issuetracker.unity3d.com/product/unity/issues/guid/1106575/

    On an older device (iPhone 6) our game ran fine on iOS 11... Others had reported it not working for them on iPhone 6, and they were all running iOS 12, we decided to update and the app would crash due to memory usage. The app is built with Unity 2018.2 and the latest XCode

    No, it's not Fixed in the latest iOS version 12.1!!! And it is not about the change in memory usage tracking from iOS 11 to iOS 12. Read this thread carefully, please: https://forum.unity.com/threads/ios-12-large-memory-usage.558550/

    This is specifically about the issue caused by memory tracking changes in iOS 12. According to Apple and our testing these are resolved in iOS 12.1.
