Xcode does not run the app on simulator. (App exited unexpectedly)

ios, ios7, objective-c, xcode, xcode5

Solution

My problem was the debugger. Actually, it still is. The way I solved, and have been doing for every new project, was to disable the debugger and then run the project. That way I'm able to use the app on the simulator but without the debugging functionality.

I don't know what the problem is, what is causing this debugger issue in my case, but for now that's the best I could come up with. Thanks to the friends that replied to my question and helped my research I was able to test it and disable it.

This is how I disabled the debugger:

- Project > Edit scheme

- Set `Debugger` to None

If anyone knows a solution for this, feel free to answer this question and I'll make sure to update the selected answer accordingly.

Again, thanks for all your time and patience, specially @Popeye and @HotLicks that spent a lot of their time trying to help me.

Problem

I'm developing for iPad (iOS 7), using Xcode 5.0.2. Yesterday morning I was playing around with the app (my first app) and every time I ran it, it was displayed in the emulator perfectly. But after some 5/6 runs Xcode just stopped launching my app in the simulator. I started to receive this message: MagazineManager exited unexpectedly - lost connection Image: I've been researching since yesterday morning for a solution with no luck. I even uninstalled and reinstalled Xcode, cleared the cache, delete folders... all that drama thinking it could be some sort of cache problem. Then, going online I've tried lots of "solutions", none worked. I've tried all listed here: Xcode suddenly stopped running project on hardware: "Could not launch xxx.app: .. No such file.." and here:https://discussions.apple.com/message/23431537#23431537 and in more places. After all my "try this, try that" I'm stuck with the same problem. I can only see a black screen at the simulator (image below) and that message at Xcode! In my extensive research I've read that people are still able to debug using their iPad's. The problem is that I got the new iPad air, that's only getting here dec, 20th!! So I don't have a place to test my app[s]. Thanks! UPDATE Just got this message in the debugger console: 013-12-09 20:23:25.902 sim[607:303] /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/usr/bin/sim: Did not find an executable file at the path: '/Users//Library/Developer/Xcode/DerivedData/MagMan-bvhhiijesvrvuteunbmpsxcqgsst/Build/Products/Debug-iphonesimulator/MagMan.app'
