New Freebie: iOS 10 GUI Now for iPad
New Freebie: iOS 10 GUI Now for iPad is a free UI Kit design resource made by Dribbble user Alexey Rybin. As far as I can tell, its license is Custom License.
Helpful hint: Dribbble users are nice. If the license is unknown, it is usually because they forgot to mention it explicitly; not because they were being stingy. Ask nicely and they will probably allow you to use it.
