Xcode Extension isn't show up in the Editor menu

There was a ‘recent’ change in the way that Xcode editor extensions should be built [1], and it seems that the Xcode template hasn’t caught up with that change (r. 59274389). So, to fix your problem, do this:

1. In the Project navigator, select your project on the left.

2. In the project editor, select your extension target.

3. In the General tab, scroll down to Frameworks and Libraries.

4. Find the XcodeKit.framework entry.

5. Change the Embed setting from Do Not Embed to Embed & Sign.

[1] Search the Xcode 12 Release Notes for 59274389.

If it is None or Sign to Run Locally, isn't show up.

That doesn’t surprise me. For day-to-day development, I strongly recommend Apple Development signing. The easiest way to get that is to enable automatic signing and then select your team from the popup.

Oh, and the reason why that’s so important is that it gives macOS a way to track the identity of your code. See TN3127 Inside Code Signing: Requirements for all the gory details.

So, it looks like having multiple versions of Xcode on the same machine (Xcode 16.2 release plus a couple of betas for 16.3) means this doesn't show up.

 @DTS Engineer Is there a way to do this while having multiple versions of Xcode?

I found this Github thread but it doesn't seem to work for me: https://github.com/nicklockwood/SwiftFormat/issues/494#issuecomment-547101989

I've also tried the trick of renaming Xcode.app and moving it in and out of the Applications directory to (allegedly) refresh some cache somewhere but no luck

Hmmm, it’s Xcode source editor day here on the forums! You go for months without a question about this tech, and then you get two on the same day.

Is there a way to do this while having multiple versions of Xcode?

Absolutely. I can’t remember a time when my Mac has only had a single copy of Xcode. Right now I have 16.2 in the Applications folder, and 16.1 and 16.3b1 in my XcodeZone folder.

Getting your source editor extension to show up can be tricky. However, I always seem to manage to get it working. I just tested the bring-up process myself, and it didn’t give me too much grief. See my instructions here.

That should get you up and debugging. Once you get to deployment well… I have suggestions on that front too, but lets crawl before we run, eh?

TLDR: Good news, those instructions worked for me!

Notably, I followed those instructions twice, the first time for my existing project and the second time from scratch using your steps (including selecting the 'Mac app' template)

It seems the only different between my setup and yours:

I use the macOS > App template

Whereas I was using the 'Multiplatform > App' 😬

I've filed a bug report under number FB16853042 for this via Feedback Assistant linking the above threads too.

Also, OOI, where is your XcodeZone folder? I'm wondering if I should keep my main Xcode in Applications and keep the betas / older versions in another part of disk just to prevent any other weirdness (I've seen things like this before where multiple Xcodes can conflict)

Yay!

where is your XcodeZone folder?

It’s ~/XcodeZone:
