SAN FRANCISCO -- Apple unveiled dozens of new features for its iOS mobile operating system and OS X for computers.
What are the highlights? Here are ten of them:
1. Home automation. All those apps for dimming the lights, opening the front door and turning on the stereo will now be accessible from within one new Apple home on the iPhone and iPad. You'll also be able to use the Siri digital personal assistant to voice your commands.
2. Healthkit. Similar to what Apple is doing in the home, tying together the various apps for tracking calories and steps into one place. And the app can be accessed by your doctor or hospital to track your health.
3. Messages: Soon, when you compose a text, you can compose a text message with an audio reply.
4. Attachments. In OS X Yosemite, the operating system upgrade for computers, Apple is offering a much bigger attachment limit for e-mails — up to 5 gigabytes.
5. Caller ID everywhere. When your iPhone rings, you'll see called ID on Macs and iPads as well, and can answer the phone in both places. You'll be able to make phone calls from there as well.
6. Siri. She'll be in more places. You can ask the Shazam music discovery app to find a song for you, or buy tunes on iTunes via Siri.
7. Keyboard. Android keyboards are known for being able to "Swype" by moving your fingers around to compose. It's coming to iOS 8 too.
8. iCloud: Folks can share more than just photos in iCloud, accessible among multiple devices. New pricing announced too: 5 GBs free, or 20 GB for 99 cents monthly.
9. App Store upgrade. Apple is adding search tools to make finding apps easier in the App store. Additionally, you'll be able to buy multiple apps at one time.
10. Apps within an app. You'll be able to open a photo, and access a widget, like VSCO Cam photo editor, for instance, to edit the app within the app.
Here's our play-by-play recap of Apple's keynote as it kicked of its WWDC14:
2:57 p.m.: Tim Cook wraps up the keynote. Overall, some subtle tweaks for iOS 8. However, it appears big changes are in store for developers working on iOS apps. Thanks for joining us.
2:55 p.m.: Following a demo breaking down how coding apps will work with Swift, Federighi confirms a beta version of iOS 8 will be available for developers today. It will be available to all users this fall.
2:47 p.m.: Apple says the SDK will introduce a new programming language called Swift, which Federighi describes as a more modern service. This has generated arguably the loudest applause. "Do you know how many people at home are going, 'what the heck are these guys talking about?,'" Federighi quips.
2:45 p.m.: Another tool for the software development kit: SpriteKit, which helps developers with physics and lighting. There's also SceneKit, which boasts a 3-D scene renderer. Translation: expect iOS games to look a lot better within the next several months.
2:42 p.m.: Sweeney demonstrates a powerful demo with impressive visuals. The demo shows petals blowing in the wind from a tree, as well as a koi pond with dozens of fish. Really sharp.
2:40 p.m.: Federighi discusses Metal, which he says marks a jump in three-dimensional graphics. He says they're working with game engine platforms from companies such as Electronic Arts, Crytek and Epic Games. Federighi demonstrates Plants vs. Zombies. Federighi says the Frostbite engine, EA's tech for console games such as Battlefield, works on the phone. About to get a demo from Epic's Tim Sweeney.
2:38 p.m.: And here comes the home automation. Federighi breaks down HomeKit, which can work with locks, lights, cameras, thermostats or other objects. Siri integration allows for commands to control the home, such as turning off lights or closing the garage door.
2:36 p.m.: Federighi confirms Touch ID, the fingerprint sensor feature on the iPhone 5s, will work with third-party apps. Mint was among the apps featured with Touch ID.
2:34 p.m.: Federighi says users will have the option for third-party keyboards, which gets a lot of applause from the crowd.
2:32 p.m.: Federighi can also organize their widgets to appear in Notifications how they choose. Apps seem to work a bit more cohesively with each other with Safari when browsing. Very easy.
2:29 p.m.: Federighi returns to break down the software development kit (SDK) for Apple devices. He discusses extensibility, where apps can work better with each other. He cites Safari enabling options such as Pinterest sharing. It can also enable widgets within Notifications such as sports scores.
2:26 p.m.: Another new App Store feature for developers: TestFlight, which will allow developers to beta test app with users.
2:25 p.m.: Tim Cook returns to chat about the App Store, which features 1.2 million apps and 300 million visitors a week. More than 75 billion apps have been downloaded. "What we want to do is to make the App Store even better," he says. Cook says an Explore tab will help users find apps more easily. Trending searches will also be available, as will top-down continuous scrolling results and Editor's Choice. Developers can build app bundles for the first time, so users can purchase multiple apps at a discount. The store will also include app previews to highlight features.
2:22 p.m.: For iCloud, users will get the first 5 GB of storage free, with 20 GB for 99 cents. Moving on to Siri, the voice assistant will include song recognition, the option to purchase iTunes content, streaming voice recognition and a "Hey Siri" command to call up Siri without touching your phone.
2:21 p.m.: Federighi says similar photos editing tools will be available on Macs early next year.
2:18 p.m.: Federlighi demonstrates the photo editing features. Light adjustments are completed by simply swiping left to right with your finger. All changes are updated and stored in iCloud, changing immediately on multiple devices.
2:15 p.m.: The best feature might stop those accidental app purchases. When a child tries to purchase an app, the parent receives a request to grant permission for that download. Shifting gears to Photos, users can search with more detail, such as by album or location. There also also smart editing options and auto-straightening.
2:13 p.m.: Federighi moves to Family Sharing, comparing it to sharing photos on the refrigerator. Family members can share photo streams, reminders, calendars or "find my kids' devices." All family purchases sync together between devices as well. It works with up to six family members.
2:11 p.m.: Here comes the health portion of the discussion. Federighi confirms HealthKit, a single place for applications to contribute "a composite profile of your health." A Health app measures the most important metrics, and works with third-party apps. Nike is among the partners. Apple says they're working with Mayo Clinic to automatically manage wellness plans and vital signs, resulting in "more timely care," says Federighi.
2:08 p.m.: Federighi shifts gears to enterprise, saying 98% of the Fortune 500 works with iOS. Apple says a device enrollment program will let companies get devices straight from the box configured to fit their needs. The new operating system will add better encryption and VIP threads, which gives users notifications for important updates.
2:06 p.m.: Federighi returns to discuss iCloud Drive again, which will work on iPhone and iPad.
2:03 p.m.: Back to Tap to Talk: an Apple demonstrator showcases Messages by sending an audio message in the thread. Very simple and seamless. Users can listen and reply to audio messages by raising the phone to their ear.
2:01 p.m.: Messages include Tap to Talk, allowing users to tap and hold the screen to record audio. There's also a Details button with information on friends' locations and which friends are on a thread. Users can share their locations temporarily or for a longer period. Users can also set Do Not Disturb for more active conversations.
1:58 p.m.: The keyboard gets an overhaul with QuickType, which will feature predictive text and is context sensitive. Federighi starts a sentence with "the meeting was.." and can predict the tone of a sentence.
1:57 p.m.: Spotlight suggestions add more details, such as points of interest, Wikipedia entries, songs on iTunes or movies in theaters and on iTunes. The mobile version of Safari includes the same search options.
1:54 p.m.: Federighi takes a tour through iOS 8, starting with actions you can accept or decline straight from Notifications. Users can also respond to Messages, or comment and like Facebook posts straight from notifications. When double tapping the Home button, users not only see open apps but recent contacts.
1:51 p.m.: Cook confirms iOS 8. "This is a giant release," he says.
1:49 p.m.: Cook says almost 9 out of 10 iOS device owners are running the latest operating system. An impressive effort considering the massive changes to the operating system made last year. He compares that to Android, where only 9% of users running the KitKat OS.
1:47 p.m.: Here's a jawdropping number: Tim Cook says Apple has sold 800 million iOS devices, half a billon of which are the iPhone. That's a lot of devices. Cook takes a moment to dig at Google, claiming a lot of users switched to Android. "They sought a better experience, and a better life and decided to check out iPhone," jokes Cook.
1:45 p.m.: Like Mavericks, Yosemite will be free to users. The developers preview launches today. This summer, users can sign up for a beta program to get an early look.
1:44 p.m.: Instead, Federighi demos the phone feature by calling Apple's latest employees: Beats co-founder Dr. Dre. "I can't wait to get to work with the team at Apple," says Dre.
1:42 p.m.: Federighi demonstrates the phone feature with a call from his mom. The audience groans when he turns down the call. "I'm sorry," he jokes. "She's a wonderful, wonderful woman, but this is my space."
1:40 p.m.: Macs can also double as a phone? Federighi says OS X Yosemite will add a Caller ID and allow users to use their computer as a speaker phone. Users can even make calls from their Macs.
1:37 p.m.: A big win for fans of AirDrop: the tool that lets users quickly share photos or other items works across Macs and iOS. So, a user can take a Mac photo and easily AirDrop that onto a phone. There's also Handoff, where devices immediately recognize what you're doing and allow you to pick up a task when switching between devices. There's also Instant Hotspot, where users can easily turn their iPhone into a Wi-Fi hotspot for their Mac.
1:35 p.m.: The email Markup tool is really interesting. Users can take an image in Mail and add elements such as arrows to point to an object or word bubbles. Markup recognizes the items and polishes them for use in messages.
1:32 p.m.: Safari features a sidebar that brings up bookmarks or other links. A sample of a search of Ansel Adams brings up Spotlight results with a Wikipedia page that instantly pops up on results. The design is similar to Chrome. Minimal space for address bars and tabs, while web pages take up the overwhelming bulk of the browser real estate.
1:29 p.m.: Moving on to the Mail Drive feature, Federighi says it was created to solve the issue with sending large attachments. The feature sends encrypted attachments that make it easier to download. Web browser Safari gets a subtle overhaul as well, minimizing the toolbar and letting users bring up favorites by tapping the address bar.
1:25 p.m.: Federighi breaks down the next big OS X feature: iCloud Drive. It works across Macs and mobile devices, syncing across all of them. "What the heck, we're throwing in Windows, too," he jokes.
1:24 p.m.: Spotlight searches contacts and provides basic information, but also whether they're involved in similar events or appointments as the user. There's some inline app use from search results as well. Reminds me a lot of how Google search might work.
1:22 p.m.: Calendar gets a few tweaks, including a new Day view with detailed information on appointments or events. Notification Center includes widgets from third parties, such as ESPN. Functions similarly to the way notifications work on the iPhone.
1:20 p.m.: Spotlight has been refined, too. A search bar pops up in the middle of the screen, where users can seek out apps or specific files. Federighi is about to roll through a live demo.
1:19 p.m.: Shifting to Notification Center, which adds a Today view with current appointments and weather. There are also widgets for topics such as News, Sports or even a calculator.
1:17 p.m.: Federighi digs a little deeper into Yosemite. The icons get a new look, while the fonts include more "consistent and clear type," he says. Very subtle changes. There's also a Dark mode, which gets lots of applause from developers.
1:15 p.m.: Cue the next montage starring Yosemite. The menu interface looks a touch sleeker than Mavericks.
1:13 p.m.: Craig Federighi, Apple's senior vice president of software engineering, unveils the latest version of OS X, called Yosemite.
1:10 p.m. OS X takes spotlight first. Cook says the Mac install base has hit 80 million. While the personal computer industry has experienced a 5% dip in growth, Mac growth is up 12%, says Cook. The Apple chief also note Mavericks was the fastest adopted computer operating system, with more than half updating. By comparison, only 14% of PC owners jumped to Windows 8. "Need I say more?" says Cook.
1:09 p.m.: Cook says keynote will focus on OS X 10 and iOS, and the "mother of all releases" for developers. Cook says Apple has 9 million developers, up 50% from the year before, the biggest climb ever.
1:07 p.m.: This is the 25th anniversary of the Worldwide Developers Conference, which started in 1990 with 1,300 developers. Safe to say it's a little bit bigger now. Cook says the youngest developer in the audience is 13.
1:06 p.m.: Montage over. Apple CEO Tim Cook takes the stage to huge applause. "We're here today and all week to celebrate the developer community."
1:04 p.m.: Now people are sharing their best apps of all time. This jumps into a peek at a baseball app that helps coaches break down a player's swing. Very cool.
1:01 p.m. ET: The event starts with a video montage of people explaning who developers are and what they do, and the apps they can't live without. And, naturally, someone is taking a selfie with full duckface. Because we don't see enough of that online.
