Appodeal SDK "símbolos duplicates para architecture x86_64"

He implementado Framework Appodeal, pero después de eso no puedo build mi proyecto porque da el siguiente error.

duplicate symbol _OBJC_IVAR_$_MoPub._globalMediationSettings in: /Users/ci-13/Library/Developer/Xcode/DerivedData/myproject-ewtecqfvsvbwpmbxhdskxxrchrda/Build/Intermediates/myproject.build/Debug-iphonesimulator/myproject.build/Objects-normal/x86_64/MoPub.o /Volumes/Projects/myproject/Appodeal.framework/Appodeal(MoPub.o) duplicate symbol _OBJC_CLASS_$_MoPub in: /Users/ci-13/Library/Developer/Xcode/DerivedData/myproject-ewtecqfvsvbwpmbxhdskxxrchrda/Build/Intermediates/myproject.build/Debug-iphonesimulator/myproject.build/Objects-normal/x86_64/MoPub.o /Volumes/Projects/myproject/Appodeal.framework/Appodeal(MoPub.o)
