Cannot export Apple ID from Xcode 9

Question

I'm trying to export my Apple ID from within Xcode 9.

The error message that appears says:

Couldn't communicate with a helper application.

Try your operation again. If that fails, quit and relaunch the application and try again.

I did restart everything and also recreated my certificate - without luck.

My OS is macOS High Sierra.

How to solve this?

Answer 1

You can run this code in Terminal, and then restart Xcode.

xcrun git config --global user.email your@email.com
xcrun git config --global user.name your name 

Answer 2

我有同样的问题，但在更新到Xcode 9.3.1时解决了。
