I am building an ios navigation app that is not opening in the ios simulator

I have this navigation app with se开发者_如何学运维veral views and no data yet.. however I had a small break from coding over the weekend and have come back to it only to have it not load in the ios simulator.

There are no errors in the xcode output while it runs but as soon as i click to run button it loads the app up but as soon as it opens it closes and goes to the home screen.

I have tried cleaning the build and opening closing everything but just cannot figure this thing out...

Since there is no error messages or indication as to what is wrong I am going to suggest a few other things you can try out:

Have you tried "iOS Simulator" -> "Rest content and settings".

In Xcode click the "Product" menu in the menubar, hold down the Option key and you should see "Clean" change to "Clean Build Folder".

Lastly pull up Organizer (Shift+Command+2), select the "Projects" and the then click "Delete Derived Data".

The two last ones should not be directly related to the simulator, but they won't hurt either.

Does your app requires internet connection to run.. if it does, check ur internet connection as well.

I have this kind of problem last time and turn out, if there's no internet connection and you didn't put any exception on that, the app will straight away crash with no errors..
