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)

... 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()

我使用此代码转到新故事板，并将变量X传递到新故事板中的viewController

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let homeViewController: UIViewController = mainStoryboard.instantiateViewController(withIdentifier: "ViewControllerCall")
homeViewController.myVar = "x"
self.present(homeViewController, animated: true, completion: nil)

但是我得到这个错误：

类型“ UIViewController”的值没有成员“ myVar”
