Safari web inspector is only showing Sources, Console and Audit

Question

After upgrading to Xcode 11.3.1, I am having problems using Safari web inspector with the iOS 12.1 simulator. Every time that I run an app inside of an iOS 12.1 simulator device, it will show up in the Safari debug menu and allow me to connect to it, but the only tabs I will see are Sources, Console and Audit.

Here is a screenshot of the inspector attached to an instance of the Safari browser inside of the simulator.

Is there any way to resolve this?

Environment:

• MacOS 10.14.6 (18G95)
• Xcode 11.3.1
• Safari 13.1 (14609.1.20.111.8)
• Simulator Version 11.3.1 (SimulatorApp-912.5.1 SimulatorKit-570.3 CoreSimulator-681.17.2)

Answer 1

Web Inspector engineer here...

This appears to be a bug in Web Inspector, and we are investigating the issue. Does it happen if you use a recent Safari Technology Preview to inspect your older iOS devices?

In addition to asking on SO.. it is strongly recommended to report bugs pertaining to developer tools at https://feedbackassistant.apple.com/ so that you get notifications about followup questions and when a fix has been shipped.

EDIT(May 14): The issue is fixed in our tree and the fix should be included in Safari Technology Preview 107 and the next major Safari release. Stay tuned for release notes.

I don't yet want to update my macOS from High Sierra, but I still run into this bug (even on a clean installed test system).

Elsewhere it was suggested to use Safari Technology Preview - but now it's only for Catalina an Big Slur.

Fortunately you can still download older versions using Archive.org (bless their hearts).
This is the latest I found for High Sierra (Release 80, Posted: April 12, 2019):

I guess you can find a later one for Mojave too.
