The Evolution of Apple's Design

For its first six iterations, the design of iOS remained fairly constant. The original design made heavy use of skeuomorphism, with interface elements mimicking real life objects and surfaces. Game Center had green felt like a game table, the calendar had wood borders and simulated paper pages that could only be viewed one at a time. Perhaps the most ridiculous situation was the Contacts application on iPad, which had black borders on the top and bottom because the application itself had to mimic the dimensions of a book or a planner. This type of design was helpful when introducing the world to multi-touch interfaces, but as time went on it became impossible to ignore how they imposed the same limitations of the physical objects they mimicked onto the device's digital interface.

There's more history beyond the design shift from iOS 6 to iOS 7, but the changing of Apple's executive positions isn't really interesting or relevant from a consumer perspective. Suffice to say, iOS 7 brought about the first major redesign in the history of iOS, and that design had to be put into place in a very short span of time. Because iOS 7 was a rapid redesign, it didn't have the level of refinement that one could expect from a mature user interface. The beta cycle for iOS 7 made this very clear, with the first releases using incredibly thin font weights that Apple soon thickened as feedback came in from developers and users about the poor balance between aesthetics and usability.

Perhaps one of the biggest changes in iOS 7 was the removal of the lines and borders that had previously been used to separate the different parts of the interface. While iOS 6 made it very clear that a button was a button by giving it shading, a drop shadow, and a border, in iOS 7 a button was just some text or a glyph sitting on a view. Views themselves often didn't have obvious separators either. As Apple refined their design in iOS 8 and iOS 9 it became more obvious which parts of the UI represented buttons and other views that the user could interact with, and Control Center provides a good example of this.

iOS 10 brings the biggest change to the design of iOS since iOS 7. iOS 7 pushed the design ideology as far as possible, and it ended up going too far by making it difficult to distinguish different parts of the UI. iOS 10 takes a step backward from that and finds a middle ground between the bleeding edge design that iOS 7 adopted and the more segmented design of an OS like Android or earlier versions of iOS. To illustrate what I mean, I've included some screenshots below illustrating how key areas of the interface have been revamped in iOS 10, including the previously mentioned Control Center.

As you can see, iOS 10 makes it much more clear how different views are separated from each other using what could be described as bubbles or cards. The use of cards seems like something many operating systems are moving toward, with Android using paper-like cards for the UI ever since the original launch of Google Now. In Apple's case, the cards replace what were previously rectangular views that bordered the edges of the display with sharp corners and minimal separation between elements. In the case of notifications and widgets, what were previously sections in a table view with completely transparent backgrounds are now individual bubbles for each item. The improvement to clarity here is pretty obvious, and having a separate card for each item makes it more obvious that they're a tappable element

Control Center receives significant visual and functional changes as well. Like notifications, it's no longer a rectangular view, and is instead a card that comes up from the bottom of the display. Apple has continued their trend of making the distinction of buttons and their selection states more obvious as well. In iOS 7 the buttons were just icons that turned from black to white when tapped, and in iOS 8 apple removed the borders and instead distinguished the icons by using a different transparency effect to separate them from the background view. They also used a full white fill to indicate selection instead of changing the button outline from black to white. In iOS 10, the buttons are now even more distinct, with an ExtraLight VisualEffectView being used for the background and the buttons using something closer to the Light VisualEffectView setting. It's now much more obvious when buttons are selected as well, with the fill color being blue and the inner glyph changing from black to white.

The other big change to Control Center is the new layout. Previously Apple placed all controls on a single view, but in iOS 10 Control Center now uses a PageViewController to place the toggles and settings on one section, and the music and Airplay audio output controls on the other. This allows Apple to increase the size of controls that were difficult to hit, such as the sliders for music playback and brightness. However, they've made some very questionable decisions with the size of buttons. I don't understand why Night Shift needs such a giant button when it's still just a toggle like the four buttons below it. This situation gets even more ridiculous on the iPad, which still uses two separate pages and just has comically large buttons in both sections. There's no reason the controls couldn't have been fit onto the screen at once, and UIKit's PageViewController class provides a really simple way to achieve exactly that functionality when space permits.

What is nice about the larger buttons is that you'll rarely have issues hitting the music controls. Having the second page dedicated to music means that the scrubber and buttons can be much larger, with more spacing between to prevent tapping the wrong thing. Control Center also remembers your last page so if you generally use toggles or music more it will remain positioned on that page when you bring it up again. As far as usability goes, the new Control Center is a definite improvement. I prefer the new aesthetic as well, but I find some of the size and layout choices to be questionable, especially on the iPad.

The same design changes that you'll find to Control Center and notifications exist across the entire OS. Views that were previously rectangles that bordered the edge of the screen are now floating rounded rectangles, which I generally refer to as cards even though Apple hasn't really given them an official name. The use of translucency has also been toned down in a manner of speaking. Areas that used VisualEffectViews still do so, but Apple has changed many to use the more opaque ExtraLight transparency style rather than the Light or Dark styles. In fact, everything seems to have moved up a step, with the use of Dark VisualEffectViews being almost entirely removed except for a certain part of the Maps app, having been replaced with Light views, and Light views being replaced with ExtraLight.

The design of iOS 10 still traces back to the original design principles put in place with iOS 7, but with a level of refinement that simply wasn't possible with the rapid redesign that Apple did in 2013. iOS 7 really pushed its design to the edge, with gratuitous use of transparency, no shadows, no textures, no gradients, and nothing but thin lines to separate the various parts of the interface. iOS 10 recognizes the value of separating different views into different sections, and in doing so makes it clear which objects can be interacted with and which are static.

    Really? Hiccups and frame drops make a powerful phone look weak. Smoothness adds to the sensation of fluidity of user experience. Aesthetics are a constant stimuli while using something as personal as a cell phone. Reply

    We [probably] live in the first world, what else are we supposed to have?

    And nor does first world mean developed world.

    The fact that you feel the need to differentiate between the terms "first world" and "developed world" is symptomatic of a first world mindset, as is quoting Wikipedia as an authority.

    If people are seriously concerned about " a tiny bit of judder while scrolling in safari,"
    count yourselves lucky you don't have any real problems.

    I don't live in the first world and I don't give a damn about political correctness or terminological exactitude, when all it amounts to is splitting hairs....just for the record :)

    I would't say I'm "seriously concerned" about those things, but when you're talking about a device that's beeing used extensively I absolutely think it's worth discussing user experience.

    Of course a lot of thing seems rediculous when looked at "the grand scale of things", but I still don't thing one thing has to exclude the other. It's always difficult to compare your own life to the rest of humanity, because there will probably always be someone who has a worse situation in life than you. So does that mean we shouldn't strive for quality and a good experience when using smartphones? I think not.

    If you don't live in the "first world" perhaps you'd feel more at home at an Android site ;) Reply

    Or you could look up any other source you wanted with the information at your fingertips and find I'm right about the definition. First world just meant US and it's allies, second meant the USSR and it's allies, and third world meant unaligned. Not anything about riches or poverty. Reply

    I agree, it got so bad on my iPhone 6 plus about a month ago, that I got judder scrolling from one home screen to the next, so in a fury I went and bought an S7 Edge to play with until the iPhone 7 was released. It's actually very very smooth overall and if it integrated into the rest of my kit and Apple services (Apart from Apple Music) then I might consider using it. Overall, the tight design language throughout the hardware and the operating syMornistem and polished first party features made me order the iPhone 7.

    iPhone used to be the smoothest scroller and was a major factor in me staying on iPhone before iOS8 because I can't stand frame rate drops (I like my games 60+fps too) so this is also a big deal for the 7/iOS10 and how they choose to optimize in the future. The phone should never feel 'slow' in normal day to day operation using OOTB features...

    Also, take a look at those improved Javascript benchmarks, seems like iOS10 came with a CPU upgrade too!

    Now I know Anandtech won't do a day-of-release view of the iPhone 7, but when can we expect to see a review? Reply
