I am gonna write what iv done very briefly (to delete any CocoaPods from my project)..
- delete any added folder (frameworks, Pods,...)
- delete any added files (PROJECT.xcworkspace, PodFile, PodFile.lock, Pods-PROJECT.debug.xcconfig, Pods-PROJECT.release.xcconfig,...)
- just leave your original ones (PROJECT, PROJECT_Tests, PROJECT.xcodeproj)
- remove framework reference from the project on xcode
To remove the framework reference from xcode:
- Use the Project Navigator
- Select Project
- Select Target PROJECT
- Select Build Phases from the top options
- leave the default groups (Target Dependencies, Compile Sources, Linked Binary with Libraries, Copy Bundle Resources) and delete any other
