How to solve this error ”_OBJC_CLASS_$_MBProgressHUD", referenced from:?

Question

I have an existing project with different project name & workspace name. There is no podfile in the application folder. It has Pods folder with Pods.xcodeproj file. All other files are missing. But we can open and run the project using workspace file. Third party libraries are added manually. I have installed pod and created workspace with same name. I can open and run the application.

I have removed MBProgressHUD library and installed it using Cocoapods. After that I can’t run the application and got the following error message.

"_OBJC_CLASS_$_MBProgressHUD", referenced from: objc-class-ref in BlackboardGroupController.o objc-class-ref in MenuController.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

Remove all CocoaPods and Integrate again. Please do the following steps to remove Cocoapods.

1.Delete the standalone files (Podfile Podfile.lock and your Pods directory)

2.Delete the generated xcworkspace

3.Open your xcodeproj file, delete the references to Pods.xcconfig and libPods.a (in the Frameworks group)

4.Under your Build Phases delete the Copy Pods Resources, Embed Pods Frameworks and Check Pods Manifest.lock phases.

5.This may seem obvious but you'll need to integrate the 3rd party libraries some other way or remove references to them from your code.

pod deintegrate and pod clean are two designated commands to remove CocoaPod from your project/repo.

Here is the complete set of commands:

$ sudo gem install cocoapods-deintegrate cocoapods-clean
$ pod deintegrate
$ pod clean
$ rm Podfile

Clear DerivedData :

rm -rf ~/Library/Developer/Xcode/DerivedData

Close Xcode and install cocoapods again
