I have upgraded my iPhone app to universal by right right clicking the project target and selecting duplicate option. Then there was 2 choices-duplicate only and 'duplicate and transition to iPad'. I choose second one. Then a group of iPad XIB files(having same name as iPhone XIBs) called Resources\_iPad is automatically added to the app. But still when I choose iPad simulator to run the project, the app chooses only iphone XIBs. Can anyone help me to resolve this problem?
