Swift Firebase“_OBJC_CLASS_$_GPBDescriptor”错误

Question

我firebase手动导入

运行时出现以下错误：

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_GPBDescriptor", referenced from:
      objc-class-ref in FirebaseMessaging(GtalkCore.pbobjc.o)
      objc-class-ref in FirebaseMessaging(GtalkExtensions.pbobjc.o)
  "_OBJC_CLASS_$_GPBCodedOutputStream", referenced from:
      objc-class-ref in FirebaseMessaging(FIRMessagingSecureSocket.o)
  "_OBJC_CLASS_$_GPBFileDescriptor", referenced from:
      objc-class-ref in FirebaseMessaging(GtalkCore.pbobjc.o)
      objc-class-ref in FirebaseMessaging(GtalkExtensions.pbobjc.o)
  "_OBJC_CLASS_$_FIRInstanceID", referenced from:
      objc-class-ref in FirebaseMessaging(FIRMessaging.o)
  "_OBJC_METACLASS_$_GPBMessage", referenced from:
      _OBJC_METACLASS_$_GtalkHeartbeatPing in FirebaseMessaging(GtalkCore.pbobjc.o)

... clang：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）

另外，我添加了libz,libsqlite3,libc++和libcucore

在AppDelegate我添加FirebaseApp.configure()

Answer 1

主要是如果您要使用FirebaseMessaging.framework它，则需要将不同的框架与它结合使用。没有它们，您将出现链接器错误。

Firebase.framework
FirebaseCore.framework
FirebaseInstanceID.framework
GoogleUtilities.framework
Protobuf.framework

没有其他的。不需要所有这些libz, libsqlite3,libc++和libcucore
