Xcode14 Beta下Widget在iOS15失效、搜索无显示及报错求助

问题现象 #

使用Xcode14 Beta开发Widget时，仅在iOS16环境正常工作，iOS15中无法在「搜索Widget」找到，同时出现如下报错：

已验证的解决方案 #

• 检查Widget部署版本：确保Widget Extension的Deployment Target单独设置为iOS15及以下，不要仅配置主App的部署版本。Xcode14 Beta默认可能将Widget部署版本设为iOS16，导致低版本系统无法识别。
• 移除iOS16专属配置与代码：iOS15不支持锁屏Widget特性，需做版本适配：
  • 在Widget Extension的Info.plist中，删除NSExtensionAttributes下的com.apple.widgetkit.lockscreen-widget相关配置；
  • 用@available(iOS 16.0, *)标记iOS16专属的Widget实现代码，确保iOS15能加载兼容的Widget类型。
• 清理缓存重新部署：
  1. 关闭Xcode，删除Derived Data（路径：~/Library/Developer/Xcode/DerivedData）；
  2. 在iOS15设备上卸载App及Widget，重启设备；
  3. 重新打开Xcode，执行clean操作后重新编译部署。
• 检查Bundle Identifier规范：确保Widget Extension的Bundle Identifier是主App Bundle Identifier的扩展形式（如主App为com.click.distanceTester2，Widget应为com.click.distanceTester2.Widget），避免命名冲突。
• 临时降级Xcode：若上述方法无效，可暂时使用Xcode13.x版本编译适配iOS15的Widget，待Xcode14正式版发布后再升级适配。
