歪果仁是这样回答的

May be it's because CFBundleVersion key/value pair in app's Info.plist.

If your app's Info.plist does not contain a valid CFBundleVersion key/value pair.

doing a "Reset Contents & Settings" will work, would be better to set an appropriate CFBundleVersion in the Info.plist.

you can check more error info in ~/Library/Logs/CoreSimulator/CoreSimulator.log for error details also, more information about the problem in the simulated device's system log ~/Library/Logs/CoreSimulator/[Device UDID]/system.log.
