Xcode 8 - Missing Files warnings

Question

This is just an Xcode bug. If you delete or rename a file without then doing a commit, Xcode sees the discrepancy between the previous git commit and the current state of things and reports these warnings. They go away as soon as you do a git add that includes the file deletion / rename.

If you don't use Xcode source control but some other git client (like source tree or terminal), you can disable source control in Xcode and then the warnings will disappear.

Xcode > Preferences > Source control and uncheck "Enable source control"

I tried all of these (and many others) but none of them worked. After hours of trying various fixes, I found that the following procedure worked.

cd "project directory"
git add .

You will need to close XCode and reopen or future Commits may fail.

Hope this helps someone.

I solve the problem simply by this:

1. Add the culprit to the project

2. Remove the reference

This cleans the internal state of XCode and the message goes away.

How about commit in Source Control.

You may firstly have to show Packet Contents of "your project name".xcodeproj and show Packet Contents of project.xcworkspace and then delete the xcuserdata folder.

If you still cannot commit because of Couldn't communicate with a helper application problem then under your project directory try the following:

xcrun git config user.name "Your Name"
xcrun git config user.email YourEmailAddress

*Remember to reopen the project to see the effect.
