在iOS15.0及以上设备上，如出现超级签、企业签及内测包出现“此App的开发者需要更新App以在此iOS版本上正常工作”或无法安装问题，系苹果签名方式更新造成，可根据实际情况解决。
方案一
将对应Xcode工程转移到MacOS11及以上版本的机器进行重新构建出包。
方案二
在MacOS10.14及以上版本的机器上进行如下操作：
- 将原ipa文件后缀改为zip，解压。
- 执行codesign进行重签
codesign -s "iPhone Developer: XXX" -f --preserve-metadata --generate-entitlement-der */Payload/xxx.app
codesign -dvvvvv */Payload/xxx.app
其中"iPhone Developer: XXX"为对应的证书名称，*/Payload/xxx.app为解压后.app文件路径。
- 将Payload压缩，改后缀为.ipa，重新分发即可。
