[tvOS] Memory usage is consistently increasing in a tvOS build
Steps to reproduce:
1. Open attached project
2. Build for tvOS
3. Build generated Xcode project to Apple TV
4. Keep the project running for a while and look at the apps memory report in Xcode
5. Notice the memory usage is increasing all the time
RESOLUTION:
It looks like the apparent memory leak is caused by two things:
1. "Enable backtrace recording" setting being checked in the run scheme options. This is what causes the runaway memory usage.
2. 8MB virtual memory block taken by libc malloc at the startup of the application being slowly dirtied due to fragmentation. To Xcode it looks like increased memory usage. While it indeed increases memory pressure slightly, it is pretty much expected.
Both of the above do not happen on older tvOS versions, so we think that the some internal changes in tvOS itself are to blame.
We will set the "Enable backtrace recording" setting in the default run schemes provided by Unity to unchecked.
As for the 8MB allocation, there's not much we can do about it. The only fix is to significantly reduce the number of transient memory allocations, which needs a large refactor of the Unity core.

Try disabling backtrace recording in the scheme editor.
Solved it for me!
