iOS模拟器运行报错Unable to install xxxbuildiosiphonesimulatorRunner.app

前言

最近在做项目用模拟器运行，清理缓存后发现模拟器运行不起来了，报错如下：

Unable to install /xxx/build/ios/iphonesimulator/Runner.app on 8E36D100-45F6-4CC7-8DA2-1F6EB4FBAC11. This is sometimes caused by a malformed plist file:
ProcessException: Process exited abnormally:

Please try again later.

Underlying error (domain=MIInstallerErrorDomain, code=105):

解决方法：

重启Xcode和模拟器，把模拟器里对应的APP应用删除。重新运行即可解决！
