Xcode Continuous Integration - "iOS Simulator failed to install the application"

Running into an odd problem: integrations sometimes fail with this:

Test target [...] encountered an error (iOS Simulator failed to install the application.)

We test with two simulators, 7.0 and 7.1.

I tried opening the simulators on the server and clearing their contents through the ui. I also tried to delete the ~/Library/Application Support/iPhone/Simulator/7.xx/Applications data with no result.

What is frustrating is the integration process works for a few hours, then breaks with the mentioned failure message, then works.

I've looked at the logs, but no smoking gun, but I might have missed something.

Where should I be looking to debug this?

If this is just a special case of all the other questions about iOS Simulator failed to install the application, then I'd imagine I'd need the ability to run a clean up script. How can I hook into the integration process?

Update: I'm manually running this command before every integration:

rm -rfv ~/Library/Application\ Support/iPhone\ Simulator/;

with the same results. I sometimes get "iOS Simulator failed to install..."

I have also tried clearing out the simulators manually through the ui. I still get the issue.

I'm in a similar situation. While I haven't solved it yet, Xcode bots (service) use this directory for simulators /var/_xcstest/Library/Application Support/iPhone Simulator/ not ~/Library/Application\ Support/iPhone\ Simulator/ – Chris
@Chris, Danedo, have you solved this issue? – sidslog
@sidslog restarting the server inconsistently solves the issue. I have not found a complete solution as of yet. I even received the same error today. – Chris

Try to solve the issue by assigning a non-empty value to Bundle versions string, short (CFBundleShortVersionString) in the -Info.plist file. iOS 7 doesn't like an empty value for the build number. You can have a script that auto increments the bundle number by 1 every time you build the project so this field was empty. You can also assign a dummy value there to get this working.

Try: "IOS Simulator->Reset Content and Setting".
