问题
I'm getting error regarding duplicate symbols for architecture armv7. In my ~/Library/Developer/Xcode/DerivedData/Lyearn-grsqfwtcaisfvocmxxxiqgoezpco/Build/Products/Debug-iphoneos the following files exists:
libEGOCache.a
libPods-EGOCache.a
libPods-UAProgressView.a
libSDWebImage.a
libFSImageViewer.a
libPods-FSImageViewer.a
libPods-WebASDKImageManager.a
libUAProgressView.a
libPods-AFNetworking.a
libPods-ICViewPager.a
libPods-pop.a
libWebASDKImageManager.a
libPods-AsyncDisplayKit.a
libPods-SDWebImage.a
libPods.a
libpop.a
Looking at this looks like not both libPods-XXX.a and libXXX.a should exist or should be included. My project is in swift. I have one of the file in objective c. To give this file access to swift classes I included APPNAME-Swift.h. Also I have included all these in APPNAME-Bridging-Header.h as it's required by Swift classes. This problem turned up after I removed one of the pod library from my PodFile and did pod install How do I remove this?
I checked this question but it says that I'm importing .m file whereas I'm not doing that I'm always using .h files only
EDIT #1
I tried removing libPods.a from Binary Linked Libraries and the code compiled. I removed one more library and problem is back. Also after removing library from PodFile and doing pod install libPods.a` got automatically included in the Linked Binary Libraries. I tried removing it again but am still getting the error.
After doing this I'm getting new error :
ld: warning: directory not found for option '-L/Users/USERNAME/APP-NAME/build/Debug-iphoneos'
ld: library not found for -lPods-AFNetworking
After seeing answer here and removing latter entry from Library Search paths to just ($inherited) removed the first error and now just getting lPods-AFNetworking error.
This is the error log:

It looks like it's trying to include -lAFNetworking and -lPods-AFNetworking.

The problem got solved. I had a problem mostly because of updating cocoapods. Somehow updating cocoapods created two versions of cocoapods. Uninstalling it completely and reinstalling cocoapods fixed the issue after pod install.
