I am submitting my app to app store but it's only compatible with iphone and ipod. When I added the app in itunes connect it;s making me submit an ipad screenshot.
Is it mandatory for apps to be universal? How can I get around this?
In XCode Target -> General -> Deployment Info -> Devices should be set to iPhone.
If your app is only supposed to support iPhone/iPod, only upload iPhone screenshots, don't upload iPad screenshots. Same works the other way around. The only time you should upload both is if your app is universal.
It is not mandatory for apps to be Universal, nor is required to submit both iPhone and iPad screenshots, you can just submit your 3,5" and 4,0" iPhone screenshots.
If it's complaining because iPad screenshots are missing, you might want to check in XCode that your project isn't configured as Universal.
