Question

我最近通过添加项目屏幕上的+按钮将我的数据模型对象移动到他们自己的框架。我移动了所有文件，并将目标成员资格更改为AppCore，而不是App。该项目纯粹是在斯威夫特。

我将podfile更新为以下内容：

platform :ios, '10.0'
inhibit_all_warnings!

target 'App' do
    use_frameworks!
    pod 'Firebase/Core'
    pod 'Firebase/Auth'
    pod 'Firebase/Database'
    pod 'Firebase/Crash'
    pod 'Firebase/Storage'
    pod 'FBSDKCoreKit'
    pod 'FBSDKLoginKit'
    pod 'FBSDKShareKit'

    target 'AppCore' do
        inherit! :search_paths
    end
end

每当我尝试构建时，我都会遇到4个错误：

Undefined symbols for architecture arm64: "_OBJC_CLASS_$_FIRDataSnapshot", referenced from: objc-class-ref in SSWorkout.o "_OBJC_CLASS_$_FIRDatabase", referenced from: objc-class-ref in SSReference.o objc-class-ref in SSReferrable.o "_OBJC_CLASS_$_FIRAuth", referenced from: objc-class-ref in SSUser.o "_OBJC_CLASS_$_FIRDatabaseReference", referenced from: objc-class-ref in SSOperation.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已经解组并重新安装了pod，清理了项目，清理了构建文件夹，删除了派生数据等，我无法编译它。

您可以在演示项目中重现这一点，运行pod install并尝试构建。

Answer 1

Firebase的pod中的库目前构建为静态库。将静态库链接到动态库框架是不可能的 - 你的例子中的DemoCore。

尝试在Xcode构建设置中启用bitcode并进行干净构建，这有助于我解决问题
