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

Mobile

Jun 21, 2018

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)

Resolution Note (fix version 2018.2):

Fixed in the latest iOS version 12.1 (16B92)
