Same here. I use M1 Mac Mini and Xcode was running fine a week ago. Now it's dead. I can't open any project. It quits immediately with (tabController) should not be nil.. I reported this to Apple.
This is ridiculous.
Now I'm reinstalling it, maybe this will help.
It didn't.

I managed to get Xcode working, finally. What I did was:
Reinstalled Xcode and restarted mac.
Opened some other xcode-related file (a sample from the Internet)
It crashed.
I clicked "Reopen" and before it crashed again I went to File > Open Recent > Clear menu.
For whatever reason, it didn't crash so I was able to select my project and now it works fine...
Atom editor, full of plugins, a few years ago on old Ubuntu was more stable than this.
Same here.
We have listeners in the content script. In Chrome, when I set a new entry in the background page, the content script logs the change. In Safari, it doesn't work.
I also would like to know how to trigger this prompt. I had installed Grammarly and right after that, it prompted me to grant permissions to 600+ hosts... How can I trigger a similar permissions "bar"?
Update:
@bramiam
Not sure, but have you tried with a real device? In the simulator, my extension doesn't ask about additional permissions, but I tried it on the real device and it requested permissions...
From my manifest:
"content_scripts": [{
"run_at": "document_idle",
"all_frames": true,
"match_about_blank": true,
"js": [ "***.js" ],
"css": [ "***.css" ],
"matches": [ "<all_urls>" ]
},{
"js": [ "***.js" ],
"matches": [ "<all_urls>" ]
}],
"permissions": [
"tabs",
"cookies",
"storage",
"https://xxxxxxx.com",
"http://*/*",
"https://*/*"
],
