I have an app on my iPhone that was built on iOS 5 and deployed via Xcode. I recently upgraded Xcode so that I can now build on iOS 5.1. When I go to deploy the app, which still targets iOS 5, it installs a new instance of that app instead of overwriting old one. So now I have the same app twice on the phone.
Why did this occur and how can I prevent it? My app stores user data and that gets lost since it does not overwrite.
Thanks!
for new one you set deployment target 5.1 (and I am assuming that you would not have downloaded earlier sdk again from Xcode->Preferences->downloads) hence its running new instance of an app on your iphone as well as old one that you created on earlier Xcode version with the 5.0 ios sdk.
