I think you should use Siphonophores for the cover (I saw them on the children’s tv show, Octonauts). They are an interesting sea creature that are a compound of many integrated zooids. Each zooid has a high degree of specialization. They kind of act like a neural network. There is a “brain” zooid that all of the member zooids provide information to. Here is a paper that did some research.
Dolphins are awesome! Observations indicate that dolphins undergo daily cycles of activity, which include feeding, socializing, traveling, and resting. Social behavior comprises a major portion of bottlenose dolphins’ daily activities.
They’ll represent the ever changing and never 'static’ platform,
the ‘current’ push toward AR and VR,
the ‘power’ of ML,
and the ‘spark’ for new and creative apps using the ‘electric’ changes in iOS 11.
…and now I’ve run out of terrible puns. I know, it’s ‘shocking’
The cover of iOS 11 Tutorial should be a school of 11 “Tiger of Sea” - The great Barracuda.
The excellent and efficient hunter, sleek and speedy Barracuda represents the excellent brand new features of iOS 11 that provide effective and adaptive focuses on artificial intelligence, machine learning, advanced VR/AR, powerful multitasking and much more…!
White Anemone and Sea Star, the creatures that inhabit the world’s oceans run the full spectrum of colors—often in intricate patterns, advanced camouflage, and varying degrees of transparency. It would be great to showcase versatility and new patterns of iOS 11
I propose “Glass Squid” as the sea creature to be on the cover of “iOS 11 by Tutorials”. iOS 11 has brought in a lot of design changes throughout the UI of the iPhone & iPad and mostly it presents design queues in translucency. “Glass Squid” family of species has a transparent body structure that blends with the background.
