ios - 将 Google Sign In for iOS 与 Swift Package Manager 结合使用

Question

有点像 Build iOS App having Google Sign with support for Mac ，我已经将 Google Sign in for iOS 框架嵌入到一个 Xcode 项目中，但我只针对 iOS。我的需要是将 Swift Package Manager 与 Google Sign In for iOS 一起使用。
我创建这个问题是为了添加我当前的解决方案，看看其他人是否有解决方案。并尝试鼓励 Google 使用 Google Sign In for iOS 支持 Swift Package Manager :)。

Answer 1

为此，我创建了一个 XCFramework 版本的 Google Sign。见 https://github.com/SyncServerII/GSignIn.git .到目前为止，这使得使用 Xcode iOS Simulator 和实际 iOS 设备进行测试和开发成为可能。
构建后，它会在 Package.swift list 中使用，例如:

        .binaryTarget(
            // This was generated using https://github.com/SyncServerII/GSignIn.git
            name: "GSignIn",
            path: "Frameworks/GSignIn.xcframework"
        ),

(另请参阅 https://github.com/SyncServerII/iOSGoogle/blob/main/Package.swift 以获取完整示例)。
到目前为止的问题:

我显然无法访问捆绑 Assets 。我不得不创建一个新的 Google 登录按钮。没什么大不了的，但为了完整起见，我想访问 Google 登录框架提供的 Google 按钮。

此软件包取决于特定版本的 Google Sign In。更新它需要进入 https://github.com/SyncServerII/GSignIn.git并根据 Google 登录框架的更新手动更新它。

我尚未将使用此包的应用程序部署到应用程序商店，因此目前尚不清楚。

20 年 12 月 28 日(已解决 - 请参阅下面的 1/1/21 更新):我还应该注意，我在我的共享扩展中收到了有关此库的警告:

ld: warning: linking against a dylib which is not safe for use inapplication extensions:/Users/chris/Library/Developer/Xcode/DerivedData/Neebla-aybzuiaoyytaypbvqtqeummvcssh/Build/Products/Debug-iphoneos/GSignIn.framework/GSignIn

当我在我的目标应用程序中使用这个框架构建时，它有一个共享扩展。
我还没有尝试将这个应用程序上传到应用程序商店，所以不知道会发生什么。
20 年 12 月 29 日(已解决 - 请参阅下面的 1/1/21 更新):我之前在构建时将我的 Google 登录包从本地目录拖到我的应用程序中。我刚刚尝试从没有拖入，而是仅仅依靠它作为我的应用程序中的 swift 包，使用其 Github 存储库引用。这会用各种晦涩的链接器错误来破坏构建，如下所示:

请注意，这并非特定于为真实设备构建(例如， arm64 )。如果我为模拟器构建，我会收到相同类型的消息，但标题是 Undefined symbols for architecture x86_64: .
当我构建并仍然包含我的 Google Sign In 包(在我的主应用程序中有引用)，但在我的共享扩展中没有引用这个包时，它会干净地构建。我将此作为该包不能用于共享扩展的更多证据。
21 年 1 月 1 日:
我现在已经解决了上述两个链接器问题。第一个只是我需要在 https://github.com/SyncServerII/GSignIn.git 中更改的开关Xcode 项目(见 warning message linking against a dylib which is not safe for use in application extensions)。
第二个是我没有将我的框架引用(在我的情况下为 iOSGoogle)添加到我的共享扩展中。例如，参见 https://stackoverflow.com/a/61848359/1675875
2/3/21:
当我将我的应用程序上传到 iTunes Connect 时，我遇到了一些其他问题，在共享扩展中使用 XCFrameworks:
