[Extensions] Not enabling extensions due to security measures [10.15.3]

[Extensions] Not enabling extensions due to security measures


I just started seeing this message in the debug log after upgrading to OSX 10.15.3 and/or Xcode 11.3.1.


I am no longer able to run my Safari app extension in XCode. A new empty project also has the same problem.


Did something change? Or do I need to toggle some other new property / attribute?


Repro:

1. XCode, File / New Project, Safari Extension, give it a name "Test"

2. Run the App side - no issues

3. Run the Extension side, select Safari


Expected: run as normal


Actual: crash / exit with [Extensions] Not enabling extensions due to security measures in the log


----

PS No problems on my other machine with 11.2.1 and Mojave 10.14.4

Make sure that your extension preferences pane is frontmost in the middle of your screen with no other windows covering any of it.


There can also be issues when running certain accessibility software, so make sure that those are disabled if you are running into this.
