Hi Quinn, thanks for the quick reply. This is one from the simulator. This is the first iOS bug I've reported so I'm not sure what the fix proccess/timeline looks like for something like this? In the meantime, this is the workaround I'm using: private func warmUpMetadataQueries() { let query = NSMetadataQuery() query.searchScopes = [NSMetadataQueryUbiquitousDataScope] query.predicate = NSPredicate(value: true) query.start() query.stop() }Calling it once on app startup seems to prevent the crash, but I'm not sure if there are any caveats to this approach - maybe you could adivse. Best, Pablo
