Hi iOS developers,
My app has been suffering a mysterious crash that I have been hopelessly trying to figure out for couple weeks now.
Above is the crash log. It only happens on a few devices. It happens only with iOS 15. It happens when users tap on a text field and method textField.becomeFirstResponder() is called. My app is a document-based, multi window app with ObjectiveC and Swift mixed.
I'd really appreciate if anybody can point me to a direction to debug this crash. Please also let me know if you experience the same crash.
Thank you very much!
