A lot of work that “web designers” do these days is not actually for the web, but rather for mobile devices, and a good portion of this work is for Apple ios devices.
Originally ios had one look for most components of the iOS operating system, but those days are gone and at this stage many of the elements of the OS can be almost as original as you want them to be. But that does not mean you have to do a lot of original work, because folks on sites like Behance, Dribbble, and others are busy creating a-m-a-z-ing os GUI kits to share with all.
Please don’t misunderstand I am not advocating copying, but if you can cut some production time by having a better starting point and then changing elements from there, then life is good.
Here now, so great IOS GUI kits:
Orange UI Kit
Gray UI Kit
Milki/Off-White UI Kit
