System Information

macOS Version 13.3.1 (Build 22E261)
Xcode 14.3 (21812) (Build 14E222b)
Timestamp: 2023-04-23T07:42:07+01:00

错误原因 #

从日志核心提示可明确：

• 应用扩展的Bundle ID多了一个多余前缀c，变成ccom.companyname.[applicationname]，与父应用Bundle IDcom.companyname.[applicationname]的前缀要求不匹配
• iOS规定应用扩展的Bundle ID必须是父应用Bundle ID的子ID格式（如父应用为com.xxx.app，扩展需为com.xxx.app.extension），当前格式不合法导致安装失败

解决方法 #

• 修正Bundle ID配置：
  1. 打开iOS项目中主应用和所有应用扩展的Info.plist文件
  2. 修改CFBundleIdentifier字段，确保扩展的Bundle ID以父应用ID为前缀（比如父应用是com.companyname.[applicationname]，扩展应为com.companyname.[applicationname].xxx，xxx为扩展标识如share、widget等），去掉多余的c
• 同步Xcode项目配置：
  打开Xcode选中项目目标（Targets），进入「Signing & Capabilities」标签页，确认主应用和所有扩展的「Bundle Identifier」与Info.plist配置一致
• 清理缓存并重建：
  1. 执行cd ios && pod install重新安装依赖
  2. 在Xcode中按Cmd+Shift+K清理项目，再按Cmd+Option+Shift+K清理构建文件夹
• 重启模拟器：
  关闭当前模拟器，通过Xcode的「Window > Devices and Simulators」删除已安装的应用，再重新启动项目
