attempted to initialize an object with an unknown UUID

Question

I have taken SVN check-in for a project. Thereafter I have installed pod via terminal. After installation of pod there are few warning stating

Answer 1

I commented out all pods and did "pod install" then uncommented all pods to previous state and did "pod install". That solved my problem

Answer 2

For my case, I re-run pod install and find this warnings aren't showing. This is due to merging the project file.

Answer 3

My colleague and I spent hours trying to figure out how to fix a similar error:

[!] `<PBXBuildFile UUID=`050DCB84CE258104B4E8C808`>` attempted to initialize an object with an unknown UUID. `12B87A081D0745C6D77F7885` for attribute: `file_ref`. This can be the result of a merge and the unknown UUID is being discarded.

What fixed it for us:

1. identify the file that the "unknown UUID" referred to, in the .pbxproj file; in our case, it was libPods-<TARGET_NAME>.a
2. find that file in the file browser in XCode
3. delete the file within XCode
4. rerun pod install

Answer 4

Step 1: Deintegrate your project from CocoaPods. Removing all traces of CocoaPods from your Xcode project.

$pod deintegrate ProjectName.XCODEPROJ

Step 2: Install the pod Again

$pod install

Make sure you are replacing ProjectName.XCODEPROJ with your project name.

Answer 5

It still happens from time to time to me. My solution is to search after the unknown UUID in your project file and simply delete all lines you'll find.

Terminal-command:

cat YOUR_PROCJECT_NAME.xcodeproj/project.pbxproj | grep 'UNKNOWN_UUID'

You should find something like this:

UNKNOWN_UUID /* (null) in Resources */,

There could also be problem with multiple xcode version installations. Try this link for more details -
