I made my first app using PhoneGap, and have built it for iOS. I have Java and Ant properly installed and the XCode project has been apparently created. I open it in XCode and I can build it as well, from XCode. When I run it it says that error message? What seems to be problem here? Thanks guys!
Your xCode version is too old. Probably you updated the phone's OS to a newer version. Usually for each version of iOS there is a version of xCode, and if the OS is newer than xCode you get this error.
