On macOS Big Sur, after codesign Xcode and try to login to my account, got "Couldn’t communicate with a helper application"

[hyouuu]

Before codesigning, signing into my account worked normally, but after codesign it kept showing the "Couldn’t communicate with a helper application" error - I've tried restarting, delete Xcode and reinstall etc.

Posting here to try to confirm if others are experiencing the same problem on macOS Big Sur. If so, I guess there's no way to use XVim2 normally as it requires codesign? My thinking is keeping 2 copies of Xcode, one untouched to build to devices or upload to App Store, and another one codesigned to use XVim2.

Any ideas and suggestions appreciated!

I just started having this issue today after having Big Sur installed for a while with everything working fine. I deleted/reinstalled Xcode and command line tools several times and after a few tries it just started working again. Maybe this will help someone.

This issue appears after signing Xcode files by your XCodeSigner cert that needed XVim2.

Seems duplicated with #323

I agree with you.

is this issue is fixed in XCode 12.3 ? Because I do not want to download 2 versions of xcode just to get VIM running.

It is the same in Xcode 12.3. You can download IDE only one time and make duplicate for keeping without your signing.

Sorry for a dumb question but what are the steps for this? Is it just duplicate the Xcode.app from application folder and rename it to something else?

[gerram]

You should to download Xcode from Download part of Apple site (not through App Store app). It has name as Xcode_12.3.xip or Xcode_12.2.xip. It is archived Xcode.app. After unarchiving, you get archive + unpacked Xcode.app.

Download the Xcode.xip from this link https://developer.apple.com/download/more/

After the download is finished, unpack the Xcode and rename the app before moving the app to Applications folder.

Then Codesign to the renamed app and build to the renamed app.

I keep signed by my cert Xcode.app in Application folder and clear (with signed by Apple cert) in other folder. (Example in Download/XCodeClear/)

@gerram @xiifain Thanks guys. I'll give it a try.
