Attaching to appname Solution

Please note, this is not a sequence of steps. Each one is a possible solution:

1-Restart xcode and/or restart simulator (reset content and settings) and/or restart computer.

2-click on project name in project navigator. in build settings tab, go to packaging and make sure that "Product Name" is the same that the one xcode says simulator is attaching to when running. if they are different, it will
Fail.

3-Go To Your projectname. xcodeproj folder. Inside there delete anything named with your userid. When you reopen xcode those files will be recreated and it shoshould work...

4-manually delete the build directory for your project.

5-go to organizer window. select projects, select your app in the left hand side and then delete over "Derived Data"

6-check launch option is set to "automatically" in product-> edit scheme, "Run" scheme.

7-in project-> "Edit schemes"-> Run. Change the debugger from GDB to none (this doesn't make sense to me ..).

8-kill the process gdb-i386-apple-darwin from activity monitor. This is assuming GDB is not responding.

9-in "product"-> edit scheme. In run, click yourappname. app, choose other, navigate to your. app in your project. Now run.

10-check that you don't have two different info. plist in your project. If you do, remove the bad one.
