iOS stack trace in notes, logcat from Android build attached as "889446_samsungGalaxyS6edge_6.0.1.txt"

Reproduced on: 5.6.0b11
Tested on: iPhone 5 iOS 10.1.1, Galaxy S6 Edge Android 6.0.1

Notes:
* Works as intended in Play mode of editor
* After opening the project with 5.6.0b11 I was asked to do an API update, afterwards there were no console errors or issues with the build
* Unable to reproduce on 5.5.2p2, 2017.1.0a3, since console is filled with errors:
CS1644: Feature `interpolated strings' cannot be used because it is not part of the C# 4.0 language specification
CS1644: Feature `expression bodied members' cannot be used because it is not part of the C# 4.0 language specification
* These errors are present regardless whether the project is opened after opening it with 5.6.0b11 and doing the API Update or opening it "freshly" from the zip.
