This seems like such a basic task, but I\'m stumped.
How, in Xcode, do you execute a textual search though (the XML contents of) all the .xib files in a project?
I had the same problem and I resolved it using some console commands.
1) Open Terminal on your Mac
2) run "grep -i -r --include=*.xib "searchtext" /your/project/path" command
It will search in the path "/your/project/path" and will print the complete path of all files xib that use the "searchtext".
Hope this will help you!
