@jeffjohnson ah, sorry, my bad. So what's your best recommendation to this problem? Appending something to a bundle identifier? Not sure that this is the best solution because my bundle identifiers are present in multiple places and in multiple files: In Info.plist: CFBundleIdentifier In ... .xcodeproj/project.pbxpro: PRODUCT_BUNDLE_IDENTIFIER (Extension) In ... .xcodeproj/project.pbxpro: PRODUCT_BUNDLE_IDENTIFIER (Main app) I just set a user-defined variable and use it everywhere, but i don't think it's the best solution so far. Do you? You said in the article that you might unregister the app. Can this be a fix to my problem?

@jeffjohnson You said that this bug was "fixed in macOS 13 Ventura", but i'm currently on macOS Ventura now and experience this bug. The thing is that i have this bug even if there is only one app is located on the system. And when at some point the amount of apps with the same bundle id gets to 2 or bigger, macOS just makes the extension disappear instead of giving any preference to any of the apps. I attached a video in the comments showcasing the bug: https://youtu.be/abpf3q6ah98

Removing iPad, WatchOS and macOS from destinations in Xcode before publishing the app to App Store connect helped. You can find it in Project -> Targets -> {target_name} -> General -> Supported Destinations

I just recorded a video showcasing this bug, if you will https://youtu.be/abpf3q6ah98

Now if you remove the archived app in the Finder, the extension appears in the Safari Extensions settings page. But it does not work. After this if you try to restart Safari, then it crashes unless you hold down the option key. And if you try to open the extensions page, the Safari crashes unless you reboot your computer 🤡 So the question is how am I supposed to build Safari Extensions?

Just found out a way to reproduce it. Build an extension (you can use mine: https://github.com/kopyl/safari-tab-switcher) Make sure the extension is in the Safari Extensions settings page Archive the extension in Xcode (don't open, just archive) Now the extension is gone from Safari Extensions settings page

So what’s the solution?
