Error when linking

I am totally lost as I can not understand what could be causing this error.

duplicate symbol _AZSocketIOError in:
.../Build/Products/Debug-iphonesimulator/AZSocketIO/libAZSocketIO.a(AZSocketIO.o)
.../Build/Products/Debug-iphonesimulator/TLKSimpleWebRTC/libTLKSimpleWebRTC.a(TLKSocketIOSignaling.o)
ld: 1 duplicate symbol for architecture x86_64

Here is the PodFile
pod 'FBSDKCoreKit','> 4.15.0'
pod 'FBSDKLoginKit','> 4.15.0'
pod 'Firebase/Core'
pod 'Firebase/Messaging'
pod 'Google/SignIn'
pod 'libjingle_peerconnection'
pod 'TLKWebRTC', :git => 'https://github.com/otalk/TLKWebRTC.git'
pod 'TLKSimpleWebRTC', :git => 'https://github.com/otalk/TLKSimpleWebRTC.git'

I have removed every single entry to AZSocket library from the project, but I still get this error.
Does anybody else have this error?

Also, I copied the content of the xcconfig files for the pods AFNetworking, AZSocketIO, SocektRocket, TLKSimpleWebRTC, and TLKWebRTC from the ios-demo app, but in vain.
Thank you

It turned out that the problem was the following enumeration in the AZSocketIO.h file

NS_ENUM(NSUInteger, AZSocketIOError) {
AZSocketIOErrorConnection = 100,
AZSocketIOErrorArgs = 3000,
};

I replaced it with
typedef enum {
AZSocketIOErrorConnection = 100,
AZSocketIOErrorArgs = 3000,
} AZSocketIOError;

and it builds fine
