Apple’s annual Worldwide Developers Conference (WWDC) is always accompanied by a long list of updates and previews, and 2017 was no different. Along with new iPad Pros, a new iMac Pro, and the HomePod smart speaker Apple also announced iOS 11, which brought a lot of new features to iPhones, iPads, and iPods.

Apple has been under the gun to make more massive leaps like it did with the older iPhone and iOS versions, but opinions on whether it did so with iOS 11 have varied. Many fans are getting restless, and the Google side of the fence keeps looking fresher and more exciting. Is iOS 11 enough to keep Apple fans feeling comfortable with their mobile OS of choice?

TechRepublic’s cheat sheet about iOS 11 is a quick introduction to the latest version of Apple’s mobile operating system, as well as a “living” resource that will be updated periodically as it evolves.

What is Apple iOS 11, and what are the key features in iOS 11?

iOS 11 is the current version of Apple’s mobile operating system for iPhone and iPad. It has brought a lot of changes to iOS that are sure to excite users and developers alike.

Users will notice new voices for Siri, content recommendations based on search history, peer-to-peer payments via Apple Pay in iMessage, a revamped Control Center, editable live photos, a redesigned App Store, and lots more.

Developers will be able to use new APIs and kits to develop augmented reality apps, add natural language learning functions (Natural Language API), perform advanced image recognition tasks (Vision API), build third-party apps that interface with Apple Music (MusicKit), and give Siri support to third-party apps (SiriKit).

There are simply too many features to thoroughly cover here–check out CNET’s good rundown the new features in iOS 11.

Why does Apple iOS 11 matter?

Apple has built itself a reputation for innovation and creating solid products, but let’s be honest: To say it’s the innovation leader it once was would be an outright lie. The past few years have belonged solidly to Google, and Apple has been stuck playing catch up–and it hasn’t been great for the Cupertino firm.

iOS 11, and the iPhone 8 and iPhone X that accompanied its launch, weren’t the huge hits that Apple needed to improve its image in the post-Jobs era. Instead the revelations about battery throttling, disappointing sales, wireless charging issues, and repeat discoveries of iOS bugs have dragged the company down.

iOS 11’s preview promised a lot of features, and while it pushed Apple in the right direction with new augmented reality features, navigation improvements, a more human voice for Siri, and the like, it still felt rushed to market based on the number of bugs discovered.

Apple is relying on the iOS 11.3 update to fix some of the flaws iOS 11 came with. With the iOS update having just been released, it remains to be seen how the new version will be received.

Who does Apple iOS 11 affect?

If you own an iPhone, iPad, or iPod, you’re affected by iOS 11. Apple doesn’t like to fragment its ecosystem, as evidenced by its pride in the 86% adoption rate of iOS 10, so supported devices will be pushed toward the new platform.

If your device isn’t listed above, I have some bad news: It’s out of the update lifecycle. Those who don’t own an iOS 11-eligible device are going to have to get new devices if they want to keep getting updates–and that includes security patches, which means you’ll be vulnerable to new bugs, backdoors, or zero days found in iOS 10.

iOS 11 is also killing everything to do with 32 bit on both the hardware and the software side, which means 32-bit applications won’t work in iOS 11. Say goodbye to your old 32-bit apps, or hope that their developers reemerge to make an update.

What’s new in the latest iOS 11 updates?

iOS 11.4

The latest version of iOS, 11.4, is now available for public download and installation, which you can do using the Settings app.

iOS 11.4 is mainly an incremental update that fixes bugs, though several new features were added:

  • Support for AirPlay 2’s multi-room audio–this allows users to control multiple AirPlay 2-compatible speakers at the same time;
  • HomePod pairing with iPhones and iPads; and
  • iCloud messages can now be stored in iCloud, which can save iOS users valuable device storage space.

iOS 11.3

Along with the inclusion of electronic health records, more augmented reality features, and business-to-consumer chat in iMessages, Apple has added several other features to improve on the shortcomings of iOS 11, two of which stand out as particularly important for iOS users.

  • Battery health statistics have been added to the Settings app. Users can see the condition of their iPhone and iPad battery, along with recommendations on when to replace it. Users can also enable or disable the battery-saving performance throttling that made headlines for iOS 11.
  • Data and privacy notifications let users know when an app is requesting their location, personal data, or other personally identifying information. Any app that requests such data will need to be approved by the user, and a small icon will appear at the top of the screen to let users know an app is requesting personal data.

How will iOS 11 updates affect developers?

iOS 11.4

There aren’t any standout features in iOS 11.4 that affect developers, though some will be pleased by bug fixes that eliminate problems like users being unable to properly sync data with apps like Apple Health. The biggest effect professional users will see in iOS 11.4 is the added ability to store iMessages in iCloud, which could be a security issue depending on whether messages and attachments are confidential.

iOS 11.3

iOS developers should definitely look into how the new kits and APIs will change their approach to iOS coding. Augmented reality can be a boon for companies–IKEA already takes advantage of it–and it could be a great way to show off a physical product in customers’ homes and offices.

The 11.3 update to iOS adds more augmented reality features to expand what developers can do with the ARKit, which Apple claims makes iOS “the world’s biggest augmented reality platform.” Background improvements such as better environment mapping and 2D object recognition give developers much more to play with, which Apple hopes will make augmented reality more than just a novelty.

Developers who work in the healthcare industry can expect more iOS-related work as well: iOS 11.3 brings electronic health records to the iOS Health app. Quite a few hospital systems have already added support, and more are likely to begin focusing on inclusion, meaning more work for iOS devs.

Along with the inclusion of business connectivity in iMessage allowing iPhone users to chat directly with customer service professionals, API programming for iOS is the name of the game in 11. Get used to connecting apps to Apple’s ecosystem.
