Sorry for the spam. The last email's format is borken. So I reposted here. Hi, my app uses webview to render emails. However, some emails always lead to webview termination. I want to dig into the root cause of the webview termination.
1. Here is all the info I got from Xcode console when webview terminated. *2021-09-16 09:13:16.226266+0800 Outlook-iOS[4850:280029] [Process] 0x14b2c4600 - [PID=4852] WebProcessProxy::processDidTerminateOrFailedToLaunch: reason=3* *2021-09-16 09:13:16.226809+0800 Outlook-iOS[4850:280029] [Process] 0x1251d4018 - [pageProxyID=5, webPageID=6, PID=4852] WebPageProxy::processDidTerminate: (pid 4852), reason 3**2021-09-16 09:13:16.235430+0800 Outlook-iOS[4850:280029] [Loading] 0x1251d4018 - [pageProxyID=5, webPageID=6, PID=4852] WebPageProxy::dispatchProcessDidTerminate: reason=3* 2. I also opened the Web Inspector from Safari, but it just hangs and there is no output in the Console tab. I also enabled Timeline to capture the memory or cpu usage. There is no info about the termination reason. I guess that when the webview terminates, it can't send live data to the Web Inspector. The Web Inspector can't get data for the time right before the webview termination. 3. I followed the advice by Alexey: " it's probably better to analyze crash logs from the device, and to watch memory use in Simulator." How can I get crash logs from the device? I have tried two approaches, but neither works. 1. Check Settings -> Privacy -> Analytics & Improvements -> Analytics Data on my iPhone. Nothing related to Webkit or my own app. 2. Connect my iPhone to Xcode and check Xcode -> Devices and Simulators -> View Device Logs. Nothing related to Webkit or my own app. Any suggestion for me?
