Question

我阅读了所有可以找到的帖子，并且在点击粘贴到iOS上的Notes应用程序中的动态链接后第一次启动应用程序时仍然会收到一个nil URL。其实我跟着视频：
https://www.youtube.com/watch?v=sFPo296OQqk

Universal Links可以通过application(_:continue:restorationHandler:)正常工作。但是，在通过application(_:open:options:)（以前为application:openURL:options:）时，该网址为<my-scheme-name>://google/link/?is_weak_match=1。无论我如何配置我的项目/应用程序，URL始终为零。此外，无论在安装应用程序之前是否点击了动态链接，都会在每次首次启动应用时调用application(_:open:options:)。这是预期的吗？

配置：

设置了apple-app-site-association文件，看起来很适合Universal Links。
在Info.plist中设置自定义URL方案。
使用最新的GoogleService-Info.plist
不在Safari的“私密”模式下

拨打didFinishLaunchingWithOptions

请尝试连接到手机和WiFi并重复实验。此外，连接到不同的WiFi网络可能有助于找出问题。如果您的WiFi具有少量面向公众的IP地址，则检索未决动态链接可能会失败。另请参阅此回答中的建议Firebase Dynamic Links not survive installation

如果这不起作用，我建议您使用Firebase打开支持服务单。

关于您收到的链接<my-scheme-name>://google/link/?is_weak_match=1：此链接由FDL iOS SDK发送，用于通知待处理的动态链接不可用的事件。只有在首次启动应用程序后，您才会收到此链接。如果我们发现待处理的动态链接，我们将通过该动态链接。

应用程序：openURL：选项：在从Firebase动态链接按下应用程序安装后第一次打开应用程序时未调用
