使用firebase sdk和googlevr sdk重复符号的新错误

Question

我在遵循此操作时出现此错误：Unity iOS build error: duplicate symbols when using Firebase Unity SDK + Google VR SDK for Unity，我也使用Firebase SDK和GoogleVr SDK体验相同的重复符号：

"_kGTMSessionFetcherStatusDomain", referenced from: ___43-[IonNetworkHelper makeRequest:requestPtr:]_block_invoke in libgvrunity.a(ionnetworkhelper.mm.o) "_OBJC_CLASS_$_GTMSessionFetcherService", referenced from: objc-class-ref in libgvrunity.a(ionnetworkhelper.mm.o)

提前谢谢。
