How to permanently fix Xcode 5 SpringBoard failed to launch application with error: -3
提问by Kyle Clegg
Launching apps from Xcode 5 to the iOS simulator (multiple OS versions) fails with SpringBoard failed to launch application with error: -3. I can get around the problem by 'turning it off and back on again' (quitting the simulator and relaunching, uninstalling and redeploying the app, etc.), but it seems to come back again later and in other projects.
将应用程序从 Xcode 5 启动到 iOS 模拟器（多个操作系统版本）失败并显示SpringBoard failed to launch application with error: -3. 我可以通过“关闭并重新打开”（退出模拟器并重新启动、卸载和重新部署应用程序等）来解决这个问题，但它似乎在稍后和其他项目中再次出现。
Can someone help me understand what the real problem here is and if there is a permanent fix?
有人可以帮助我了解这里的真正问题是什么以及是否有永久修复？

I don't know why, but on my end deleting the app from simulator solved this.
我不知道为什么，但最终从模拟器中删除应用程序解决了这个问题。

Run Activity Monitor and force Kill the simulator process. Then Run you app again and simulator will launch automatically and problem goes away.
运行活动监视器并强制终止模拟器进程。然后再次运行您的应用程序，模拟器将自动启动并且问题消失。

3) Press run button again from Xcode

This is the quickest workaround that I have tried, did not have to delete the app or do anything like that.
这是我尝试过的最快的解决方法，不必删除应用程序或执行类似操作。

Restart simulator, if it wont solve your problem and then delete all content. It worked for me.
重启模拟器，如果它不能解决你的问题，然后删除所有内容。它对我有用。

I think this may be because you have installed (run) it on 64bit iOS7 simulator and now you are trying to use same install/files on 32bit simulation.
我认为这可能是因为您已经在 64 位 iOS7 模拟器上安装（运行）了它，现在您正在尝试在 32 位模拟上使用相同的安装/文件。

I noticed I started getting this error when manually editing files that are in the Emulator's disk space.
我注意到在手动编辑模拟器磁盘空间中的文件时我开始收到此错误。
With "the Emulator's disk space" I mean a path similar to this one: ~/Library/Application Support/iPhone Simulator/7.0/Applications//.app/
“模拟器的磁盘空间”是指类似于以下路径的路径：~/Library/Application Support/iPhone Simulator/7.0/Applications//.app/
Having the build process re-run solved my problems too so I feel like it has something to do with file permissions or some sort of checksum failure.
重新运行构建过程也解决了我的问题，所以我觉得这与文件权限或某种校验和失败有关。
