[iOS] PBXProject.AddFileToBuild method fails build when appending build folder



How to reproduce:
1. Open the attached '' project
2. Switch platform to iOS
3. Build the Xcode project
4. Build the Xcode project again using Append option

Expected result: Build succeeds
Actual result: Build fails and 'Exception: The given path Libraries/Editor/Prime31/Etcetera/P31ActivityView.h does not refer to a file in a known build section' error is thrown to the Console

Reproducible with: 2019.4.9f1, 2020.1.0a23, 2020.1.4f1, 2020.2.0a21
Not reproducible with: 2020.1.0a22
Could not test with: 2018.4.26f1 project crashes on launch

- Could not reproduce with PBXProject.AddFileToBuildSection method

  1. Resolution Note (2020.2.X):

    the error is in FyberXCodeEditor, it completely ignores headers section in xcode project

    This error happens when Unity XCode API is not able to find this header file in PBXHeadersBuildPhase section of XCode workspace. To fix it, need to add that header files in Build Phase (Header Phase) of the XCode project

    Is there any workaround/fix to this issue if I still have to use the Append option?
