For us we were running a CI job on a self-hosted github runner and encountered this error, signing in to xcode on the runner resolved this issue for us. Interestingly it wasn't necessary for macOS builds, only iOS.

Thank you Nathan, We see this on macOS Big Sur, specifically 11.5.2. FB9188594: Object graph shows strong reference only when we use Accessibility features (either by UI tests or even by Accessibility Inspector). In our AppStore app this creates memory footprint of 2.5 Gb instead of usual 45 Mb within 30 min of using the app. Basically every time user refreshes the view our memory footprint grows by megabytes. Appreciate any help!

Same issue happens by just using Accessibility on macOS, like accessibility inspector or Voice Over, not only in UI Tests. To reproduce: open your sample app open accessibility inspector focus on the current app view in inspector navigate away see object graph showing previous view model is not released

I tried setting my locale to Australia (metric) and setting the -AppleMetricUnits false in the example project and saw that the launch argument had no effect and my Locale.current.usesMetricSystem was still true. Screenshots and details at https://github.com/yuri-qualtie/UseMetricSystemDemo/issues/1

Works perfectly. Thank you!
