Have attempted to build a sticker pack for iMessage following Apple's guidelines. I have verified the sticker images are the correct dimensions, format, and well below the file size threshold. I am unable to test the sticker pack in simulator because iMessages on simulator crashes every time I attempt to build & run the sticker pack.
When I build the project and run it on my physical iPhone 7 (NOT simulator) the sticker pack loads and functions perfectly.
However when I try to run the project on simulator I see the icon for the project display in the lower portion of iMessage and then Imessage crashes. This crash happens on any iPhone/iPad in simulator. I receive a system error: "MobileSMS quit unexpectedly..."
I am running Xcode version Version 9.0.1 (9A1004) on Mac OS High Sierra 10.13
Full error report from xcode below (NOTE: I did not write or alter any code. This project only uses the default code generated byXcode for a sticker project).
