Xcode Cannot Run on the Selected Destination

I was running my app this morning and now all of a sudden I am getting the following error when I try to run on the iPhone 5.1 simulator.

Cannot run on the selected destination

The destination does not support the architecture for which the selected software is built. Switch to a destination that supports that architecture in order to run the selected software.

I deleted the schemes but still no solution.

I am using Mountain Lion. I am using xCode 4.4 (Recently upgraded to Mountain Lion and xCode 4.4)

UPDATE 1: Here is the view of my build settings:

UPDATE: Here is the actual error which prevents from it running.

You might follow the steps:

  • Quit Xcode and iPhone simulator
  • Unplug your devices
  • Goto /Users/your_usr_name/Library/Developer/Xcode/DerivedData/
  • Delete all data under this folder
  • Start Xcode again and run your project

Hope this will solve your problem.


I had this issue after updating from Facebook SDK 3.1 to Facebook SDK 3.1.1. My fault, I guess.

Inside "resources" folder, now there is a totally useless but dangerous info.plist that, if imported, may break your project file. Don't know why they included it but I believe few of us made the same mistake recently.


I found this problem with the version of Xcode 4.4. And finally I solved it this way:

Find the "Info.plist" in your project, then unselect the target membership plus on the right side view of window, it works for me.
