I built a simple demo app that implements the code that Apple provides here for instantiating an WKWebView. https://developer.apple.com/documentation/webkit/wkwebview This code causes a crash when launched from Xcode but I don't seem to have a problem if I run the installed app directly from the simulator. Has anyone else run into this issue while testing iOS 15? Are there new considerations that I need take into account when migrating my app to support iOS 15? I'm running Xcode version 13.0 beta 5 (13A5212g). Thank you!
