Hi @mwoollard, I cannot reproduce your issue on an Apple Watch Series 7, nor can I reproduce the issue when building against a 32bit WatchOS target. Its best if you move this issue to Realm-Swift and fill out the issue template so we can help you diagnose this better.

OK will do, have produced a cut down project that reproduces the issue, will add to a new issue in Realm-Swift.

This was moved to the swift repo and is getting fixed in #5188.
