一、 检查 Widget Extension 是否正确嵌入主应用

在 Xcode 中，选择主应用的 Target，导航到 "General" 标签页，确保在 "Frameworks, Libraries, and Embedded Content" 部分中，Widget Extension 被正确添加并设置为 "Embed Without Signing"。​

二、避免直接运行 Widget Extension

在 Xcode 中直接选择 Widget Extension 作为运行目标并在真机上运行, 可能会导致系统拒绝加载 Widget。

1. 选择主应用作为运行目标。
2. 运行主应用到真机。
3. 在设备的主屏幕上，长按空白处，进入编辑模式，点击左上角的 "+" 按钮，添加你的 Widget。​
4. 

三、确保 Widget Extension 的部署目标兼容设备

如果 Widget Extension 的部署目标（Deployment Target）高于真机的 iOS 版本，系统将无法加载 Widget。​请确保 Widget Extension 的部署目标设置为小于或等于设备的 iOS 版本。

四、我的调试过程。

1. 我用模拟器调试 直接运行的 Widget Extension 一直没问题， 所以在真机上也做了同样的操作。但实际上真机不可以这样操作。
2. 运行主应用，但在真机上找不到 Widget， 可以说是压根没有。 你需要在Widget Extension ->  General 中调整你的 兼容最低的 IOS 开发版本，（必须小于或者等于你 真机的 ios 版本）
