We’ve recently detected an issue in the interaction between our web application and SFSafariViewController that only seems to be occurring in the latest versions of iOS. We have a React application which is experiencing unknown errors (potentially processing XHR calls) frequently, but only when opened via a mobile application in an in-app browser. When opened in the standalone Safari or on the desktop, we are not able to reproduce the issue. We have been attempting to debug this with a desktop Safari web inspector connected to the SFSafariViewController. When the error occurs, the web inspector window disappears and the device disappears from the list of devices in Safari on the desktop. Our hypothesis is that this is related to changes in the latest version of iOS because we have only detected this error on devices running iOS 16.5 and 16.4.1 (potentially only 16.4.1a, but we can’t confirm it). Additionally, this error only began occurring from May 17th, which seems to be in line with the release of iOS 16.5. Unfortunately, we are not able to collect more information about the crash because: Xcode simulators are not yet available for the affected iOS versions. In Xcode (14.3.0), we cannot see the crash reports found on devices, namely WebKit crashes. It only shows reports from App Store Connect, thus we are not able to obtain the exact WebKit crash log. Are there any known issues with WebKit in iOS 16.5 or 16.4.1a? Is there any way that we could obtain the WebKit crash logs from a device or do you have other suggestions to better troubleshoot this issue?
