If I open one of the storyboards in my Xcode project, I get this alert:
The document [storyboard name] had 4 issues that were found and repaired.
This may be due to an SCM operation such as merging. Please save the document to fix the issues.
Multiple resources have the same name: groupTableViewBackgroundColor.
I tried saving the document, but the error kept popping up.
What is this and how can I fix this?
