Apple has unveiled its latest operating system, the iOS 12, with attention put on speed and responsiveness, with new advanced AR algorithms and Siri Shortcuts, according Telecompaper. Apple also highlighted data privacy with new anti-tracking features, and put in new ways people can control how much time they spend on their devices, apps or websites. The new operating systems is already available to Apple Developer Program members and a public beta program will be available to iOS users later this month. It will be released this fall as a free software update for iPhone 5s and later, all iPad Air and iPad Pro models, iPad 5th generation, iPad 6th generation, iPad mini 2 and later and iPod touch 6th generation. 
Apple said that with the new OS, apps will launch twice as fast, cameras will open up to 70 percent faster, keyboard will appear up to 50 percent faster and typing will be more responsive. Siri Shortcuts will also speed things up. With Siri intelligence, people can suggest an action at the right time, such as ordering a coffee in the morning or starting an afternoon workout. They can customise Shortcuts by creating a voice command to kick off the task, or download the new Shortcuts app to create a series of actions from different apps that can be carried out with a simple tap or customized voice command. Siri Shortcuts can work with any app. Developers will be able to take advantage of this new capability using Shortcut APIs. 
More and better AR
The new system features the ARKit 2 for developers, with more possibilities for creating shared experiences, such as persistent AR experiences tied to a specific location, object detection and image tracking. Designed with Pixar, a new open file format called usdz will make it easy to experience AR nearly anywhere in iOS, including apps like Messages, Safari, Mail, Files and News, delivering powerful graphics and animation features. 
Control screen time
New tools built into iOS 12 will help customers better control the time they spend with their devices. New modes in Do Not Disturb automatically end based on a specified time, location or action, and Do Not Disturb during Bedtime helps people get a better night’s sleep by dimming the display and hiding all notifications on the lock screen until prompted in the morning. Also, to help reduce interruptions, iOS 12 gives users more options for controlling how notifications are delivered. They can instantly manage notifications to be delivered quietly or turned off completely. Grouped notifications make it easier to view and manage multiple notifications at once. 
Screen Time lets users see, with detailed information, how much time they spend on apps and websites. Daily and weekly Activity Reports show the total time spent in individual apps, usage across categories of apps, how many notifications are received and how often iPhones or iPads are picked up. Parents can use the feature to access to their child’s Activity Report on their own iOS devices using Family Sharing in iCloud, and allows them to schedule times to limit when a child’s iOS device can be used. 
Reduce tracking 
The latest OS also put attention on privacy and security, with a particular focus on tracking. In Safari, enhanced Intelligent Tracking Prevention helps block social media “Like” or “Share” buttons and comment widgets from tracking users without permission. Safari now also presents simplified system information when users browse the web, preventing them from being tracked based on their system configuration. Safari will also help users develop strong passwords and to change them on time. 
Fun stuff
The iOS 12 also sports new Animoji and personalised Memoji plus more fun camera effects. These can bring Animoji, Filters, Text and Stickers to messages and FaceTime. People can use comic book or watercolor filters with their photos and videos, as well as new labels and shapes. Another feature of the new system is Group FaceTime, where multiple people can chat at the same time. People can be added at any time, join later if they want to or use video or audio to participate, which they can do frm their iPhone, iPad or Mac, but also from their Apple Watch. 
There is a novel For You tab where users can put their favourite photos in one place, combining Memories and iCloud Shared Albums. A new sharing suggestions feature prompts friends who receive photos to share back any photos and videos they have from the same trip or event.
