swift 火力基地 "_OBJC_CLASS_$_GPBDescriptor"错误

Question

我手动导入firebase

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_METACLASS_$_GPBMessage", referenced from:

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

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

在 AppDelegate 中我添加了 FirebaseApp.configure()

Answer 1

主要是如果您要使用FirebaseMessaging.framework，您将需要不同框架的组合。 没有它们，您将遇到链接器错误。

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

没有别的。不需要所有这些 libz、libsqlite3、libc++ 和 libcucore
