iOS Simulator failed to install the application 解决方法

升级xcode5 beta4以后,运行以前的代码,发现会出现iOS Simulator failed to install the application错误

google一下资料 http://stackoverflow.com/questions/12932750/ios-simulator-failed-to-install-the-application


命令行下执行

rm -rf ~/Library/Application\ Support/iPhone\ Simulator/*

从新run.verything is ok.
