Question: Q: Missing Boot Files?

I was running a client repair through Terminal on the 64 bit version of GW2. This is what was spit out at the end. How would I go about fixing this and is this something I should be worried about?

Xcode is crashing on startup. Any workarounds?

When I open an existing project (following https://developer.apple.com/tutorials/swiftui/creating-and-combining-views) in Xcode, it crashes immediately with this «(tabController) should not be nil.» error:

Are there any workarounds?

Answers

I’m getting the same error in one of my projects. A workaround for me is to open a different project, and then File -> Open Recent, so I’m not dead in the water, but this is disconcerting, to say the least.

UPDATE: Fixed mine — upon further inspection, there was a warning for me to upgrade my Xcode configuration. Things look better now!

It seems you have updated XCode recently.

When does the crash occurs ? On opening the project ? At run time ?

If you can open the project, open the Issue Navigator.
You will probably see a warning to update to new settings.
Do it.

Got the same problem.

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.

I downloaded the project and opened both in Xcode 12.2 and Xcode 12.3 without problem.

MacOS Catalina 10.15.7. That’s the only difference I see with @SunsetBoulevard (11.1)

Open a different project

File -> Open Recent

Clean build folder

Delete DerivedData content for the project

Open the project as usual

Clean build folder once again

Reinstalled Xcode and restarted mac.

Opened some other xcode-related file (a sample from the Internet)

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.

Yep. Clearly this is a major issue. I did find an apparent workaround: Open up the xcodeproj as a directory and delete xcworkspace. That appears to fix it.

Bug filed with Apple. Report this, folks: feedbackassistant.apple.com

I hit this problem on my 1-year-old Mac Mini which is running macOS Catalina version 10.15.7 (19H524). It happened after a system-crash, but probably more importantly after that system crash I upgraded Xcode to Version 12.4 (12D4e) via the Mac App store. The crash happened on my main userid (local to this Mac), but not on a different userid on this same Mac where I rarely run Xcode.

I tried several of the suggestions here. I emptied the «Open Recent» menu (and it was indeed empty the next time I ran Xcode), but Xcode still crashed. I tried using the open command to edit a source file in Xcode (this is something I do very often), and Xcode still crashed. I opened a few different source files this way, although none of them were for Swift source.

I also used the defaults command at the unix command line to delete many of the defaults which were set in domain com.apple.dt.Xcode . I didn’t delete all of them because I didn’t want to have to reset my configuration for Xcode. Removing those defaults-values did not stop the crashes.

I then downloaded the developer-example files of ‘Swift Standard Library.playground’ and ‘Crustacean.playground’. I double-clicked on the SwiftStandardLibrary file, which caused Xcode to launch. That example playground did some of it’s own initialization stuff, and once it was done Xcode was still running. I closed the playground, went to edit the files I normally edit with Xcode, and everything seems to be working fine. I have not had any crashes since then.

I am not 100% sure, but I’m pretty sure that I have never worked with a Xcode playground on this userid on this Mac. I’ll also say that I use Xcode as an editor for my own source files. Which is to say, I am never using Xcode projects (not on this mac, at least. This mac is only used for me «working from home» on my full-time job, not for Mac development. That’s why the Mac is 1-year old. ). I have filed a bug report with via Feedback, and included some crash-dumps from when Xcode was crashing. So hopefully that will help Apple find and fix whatever the bug is.

We need the rest of the panic log. Use the Additional Text area (document icon) to post it.

My panic log exceeds the character limit for the additional text option but looks the same as OPs.

Well, as stated before, I can’t surmise anything from the partial log.

Hi. I had another random restart. This is the (full) kernel panic log:
