AI-generated summary

After upgrading Xcode to 14.3, the iOS 16.4 simulator cannot be debugged using Safari's Web Inspector. It was initially thought that the issue was due to the Advanced settings in Safari not being enabled, but it was found that the switch was already turned on. It was discovered that starting from iOS 16.4, the following code needs to be added to enable Web Inspector: if #available(iOS 16.4, *) { webView.isInspectable = true } else { // Fallback on earlier versions } After making this change and running the program again, the Web Inspector can be accessed through Safari.

Background#

After upgrading Xcode to 14.3, the simulator is iOS 16.4. I wanted to use Safari -> Developer -> Web Inspector to debug, but found that it couldn't be accessed.

Modification#

At first, I thought it might be because the "Advanced" setting in Safari was not enabled. After checking, I found that the switch was already turned on.

After searching, I found that starting from iOS 16.4, in order to use Web Inspector for debugging, the following code needs to be set:

        if #available(iOS 16.4, *) {
            webView.isInspectable = true
        } else {
            // Fallback on earlier versions
        }

After setting it, run again and check with Safari, and you will be able to see it.

Reference#

Mark the webview as inspectable in iOS 16.4
