Why duplicate symbols persist after renaming?

Question

I have renamed in my static library some external github projects I want to distribute with my framework but while testing it with a client application adding the original source code of the dependency it still throws duplicate symbols, even that I renamed all the classes and external interfaces and implementations.

Specifically with the AFNetworking after prefixing SLKAFNetworking I get the following errors for all the classes when I add the AFNetworking and my static library in a test client.

duplicate symbol _OBJC_IVAR_$_AFURLSessionManagerTaskDelegate._manager in:
    /Users/gtas/Library/Developer/Xcode/DerivedData/TestNewPlugin-dilozkrbnhkoxkdozyatixmngsxx/Build/Intermediates/TestNewPlugin.build/Debug-iphoneos/TestNewPlugin.build/Objects-normal/arm64/AFURLSessionManager.o
    /Users/gtas/Library/Developer/Xcode/DerivedData/TestNewPlugin-dilozkrbnhkoxkdozyatixmngsxx/Build/Products/Debug-iphoneos/libTest-iOS.a(SLKAFURLSessionManager.o)

Any ideas? I don't quite get it.

It's the delegate AFURLSessionManagerTaskDelegate declared inside AFURLSessionManager.m that is duplicated.
