Dan, could you file a bug with the offending line of code which crashed ios17 with 9.6.10… Just so we can check it isn’t still there in 9.6.11 :)

Thanks!

I can (in my experience) absolutely confirm this.  Debugged it down to the single line of code.  Rebuilt the app with 10.0.0 (dp 6) and the issue was solved.
