iOS - could not launch ''XX", XX iphone/ipad has denied the launch request

iphone/ipad has denied the launch request是在调试时突然出现的问题，在网上查询之后，解决方案主要如下：

1. code sign的问题，重新配置signing，重新选一下Automatically manage signing；

2. building configuration的模式与证书不匹配，scheme - edit scheme  - run -building configuration - debug；

3.网友提示方法：Target  —— Capabilities ——App Groups（20190416更新）

4. 重启设备；
