How to Run the Simulator the Operation Couldn't Be Completed. (Launchserviceserror Error 0.)

Unable to run the Simulator The operation couldn’t be completed. (LaunchServicesError error 0.)

From the screenshot, it's clear that your Info.plist is missing a CFBundleVersion ("Bundle Version") key. If that key is missing, it can cause this problem.

Cant run app on simulator The operation couldn’t be completed. (LaunchServicesError error 0.)

I ran into this today. I had just changed the bundle identifier on my app, which invalidated the app id and the provisioning profiles. As a result, the app couldn't installed (with that alert). Once I made new app id's and profiles, things worked fine.

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.

Error: The operation couldn’t be completed. (LaunchServicesError error 0.)

I think the error is telling you the truth. You don't have a CFBundleExecutable key in your plist. When you're not showing raw keys, it appears as "Executable file".

Try adding it with the value $(EXECUTABLE_NAME).
