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.

    $399 for a 16GB SE, $549 for a 32GB 6s, $649 for a 32GB 7. More storage and Plus models will bump the price of course, but let's not pretend there are no options unless you spend over $800 dollars.

    Which is why Samsung isnt Android. They are a memory leak laden software mess.
  • robinthakur - Friday, September 23, 2016 - link

    Luckily for Samsung, their phones are just *exploding* in popularity so you probably don't need to worry about upgrading your S7 or Note 7 in 2 years because it will have been recalled.

    Getting an Android through phone carrier causes the longer update times. If you get an Android phone directly from Google or directly from the manufacturer then updates comes pretty quick. Lenovo is the only one that dumped security updates.
  • robinthakur - Friday, September 23, 2016 - link

    Yes, it's just a shame that most consumers won't be buying their phones in this way so it's still a massive problem, more from a security perspective, for Android.

    And the fact that Nexus 5 isnt getting the Nougat update but much inferior hardware Android One devices are! So much so for dont be evil!

    1. Maps also receives some really helpful widgets, including one for transit which allows you to check if there are any service advisories on your favorite transit lines, which has already helped me avoid delays due to subway and streetcar closures that I would not have thought to check for otherwise.

    I assume this is Google's map instead of Apple? Because I do have that widget for Google Map instead of Apple's own Map.

    2. In Notification Center you have a blurred background, and on the lock screen you get the current time and battery charge rather than the date.

    In your screenshot of the lock screen, you get current time and date instead of battery charge. I'm also not seeing the battery charge on my lock screen widget.

    Really awesome review, as an iOS developer it's really great to see a review that focuses on API changes and the benefits they can bring to coders. More of this sort of thing please! :)

    It would be great to get Xcode on the iPad so I can quickly test out ideas on apps I'm developing if I have a flash of inspiration in the night or something. I definitely see the problems with security though, and also installing things like CocoaPods would be problematic.

    I also agree that the way Android handles animations is not good, I'm currently writing an Android app and video animations are currently impossible because the video goes blank during animations! It never does that in iOS!

    nothing interesting or new... Android has had those features/customization for YEARS and Years.

    and Crapple is still not customizable.
  • damianrobertjones - Monday, September 19, 2016 - link

    Maybe the standard user doesn't care to customize anything!?
