I\'ve been running my app on an iPhone 5 /iOS 6, but when I try to run it on an iPhone 4S / iOS6 I get \"The run destination iOS Device is not valid for running the scheme N
This is similar to Kunal Gupta's comment, but I got this error after running an Xcode project on an actual iPad (the deployment target was changed to iPad and I wanted to run it on my iPhone simulator). Remember to change the deployment info after you use an actual device/simulator, especially when switching from iPad to iPhone.
