iOS 11 Highlights:

Control center: Apple is revamping the control center on iOS — the panel that pops up to let you control volume, brightness, etc. — by enlarging it and spacing out some of the functions.

Apple Pay: The company also introduced a person-to-person payment feature to Apple Pay. For example, a message that says “You owe me $20” will automatically pull up a suggestion to tap into Apple Pay, which will suggest $20 as your basic payment.

Voice assistant: Siri will speak (a little) more naturally in female and male voices and use some sort of machine learning to suggest apps that you may want to use.

GPS: Maps has a couple of updates, including indoor maps for places such as shopping malls — a cultural icon that's apparently dying, but, hey, at least it’s a start.

The Maps app will now display the speed limit of the road you’re driving on and let you know what lane you should be in. Using Bluetooth and WiFi, it will also be able to track when you’re moving in a car and give you the option to turn on a “do not disturb” mode while driving. Those who send you a message will now see an automatic reply that you’re driving, and you will see their message later. If they reply “urgent” to that message, that message will be marked as such and go through.

App Store: The store is getting a makeover, too, with tabs for games, apps that are notable that day, and a tab just for nongaming apps.

AR: Apple is also bringing more machine learning and augmented reality capabilities to the iPhone, which will help developers create apps with these features. In a keynote demo, Craig Federighi, Apple's senior vice president of software engineering, placed a digital cup, vase and lamp on a table and showed how the objects' shadows were able to interact with each other. A representative from Wingnut AR, a studio owned by “Lord of the Rings” director Peter Jackson, demoed a more elaborate AR battle onstage. These new capabilities, Federighi said, make iOS the largest AR platform in the world.
