I got a few questions.I was thinking of make a app for iPhone 4s and up and for the iPad.My question is on the iPad can i scan barcode with the iPad? Will apple let you use thing from github in your apps i was told you can't use 3 partly things in your app if i understand it right? What would be the best barcode in github to use for the iPhone and iPad for scan barcode?How can i clone thing from github with Xcode? If it work on the iPad it would work on the iPhone 4s and new iPhones and iPad without a prob? Would it be easy to start in swift for this project then object C?
