当我遵循以下操作时出现此错误：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 遇到相同的重复符号：
"_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)
先感谢您。
