I want to create a app for both iPhone and iPad. Is there any easy way for that so i don't need to create two different storyboard for iPhone and iPad? How can i change whole app font size and view height and width automatically when app run in iPad and iPhone.
You should look for Size Classes. They are the more recommended way to do that :) Take a look at this article https://www.bignerdranch.com/blog/designing-for-size-classes-in-ios/
