How to remove podspecs completely from Xcode and repo?

I've a project with huge codebase and it has 4 different target Apps.

Now there are many of views, models and controllers are common for all 4 target apps. So those common files, classes and image assets are placed in central folder and that folder is act as pod library. I've to run pod install to fetch all central code dependencies.

Here is how my Podfile file looks like.

#Pod sources
source 'https://github.com/CocoaPods/Specs.git'
source 'https://bitbucket.org/ttttt/xxxxxxxx.git'
source 'https://xx-xxxxxx/xxxxx/xxx/xxxx.git'

# Use the same pod library for all these targets
def myPods
    pod 'ABC', :path => '.' #'ABC' is name of pods in .podspecs file, which I want to remove
end

target 'target1' do
    myPods
end

target 'target2' do
    myPods
end

target 'target3' do
    myPods
end

target 'target4' do
    myPods
end

Here, ABC is project name. and it imports ABC.podspecs at local path.

Now, I want to remove ABC.podspecs files and make all code locally (not as pod library).

Can anybody please suggest me how to do that? If I remove it directly and run pod install, it gives lots of errors and architecture issues.

Solution

I found it!!

What I did is, moved all dependency targets into PodFile. and then removed ProjectName.podspecs file from the project. Then deleted Pods, pod lock file and workspace, and run pod install again. This process removed all development pods and dependencies from the pods project.

After that, for all central files, classes, assets, I've set all 4 target as target membership from right inspector in Xcode. and it worked well.
