At Apple’s June 2018 Worldwide Developer Conference (WWDC), iOS 12 was unveiled to the world in a massive 2 hour 15 minute keynote presentation. Apple didn’t waste any time and brought up the elephant in the room: Performance on iOS.
Apple had been under fire for many years for shortcomings with its mobile operating system, including widely publicized bugs and performance issues. With the iOS 12 update, Apple doubled down on performance and ensured the new version of its mobile operating system works smoothly on all iOS devices that it supports. iOS 12 includes improvements to Siri, iMessage, FaceTime, and tools to help you be more aware of, and control, your device usage.
This iOS 12 cheat sheet will be updated on a regular basis to reflect the latest information about the mobile operating system.

What is iOS 12, and will it work on my device?
iOS 12 is the 12th major iteration of Apple’s mobile operating system called iOS. iOS 12 offers a slew of welcome stability and performance improvements, along with new features that are sure to excite users. For starters, iOS 12 promises improvements around app launches, which any user will be happy to hear.
iOS 11 was able to run on many devices, dating all the way back to products released in 2013. Any device that is capable of running iOS 11 will also be able to run iOS 12, thus extending the lifecycles of devices, which could benefit enterprises that provide employees with Apple mobile devices.

What are the key features in iOS 12?
iOS 12 includes numerous performance improvements, including 70% faster access to the camera from the Lock Screen; 50% faster keyboard appearance; and 2x faster app launches when the device is under a heavy workload. All of these performance improvements are likely to significantly impact older devices, but will also boost newer devices like the iPhone X, the iPhone Xs, and the iPad Pro, which are more capable of background tasks and less likely to run into strain under heavy workloads.
The other big change with iOS 12 is the ability for Siri to integrate with nearly all apps through a feature called Shortcuts. Developers will be able to provide a UI to users that gives them the ability to record a custom phrase that activates the app from within Siri on either iPhone, iPad, or Apple Watch. Apple announced that support for Siri Shortcuts will extend to the recently released HomePod as well. A user can activate these shortcuts from the HomePod as long as the user’s iPhone or iPad is connected to the same network and is nearby.

Apple’s recently acquired Workflow app has made a rebranded appearance as the Shortcuts app with minor UI changes. This app now integrates with Siri and the system more seamlessly to allow users to chain together actions from multiple apps in the Shortcuts app to make automation workflows that are voice activated.
A big change to iOS 12 is the redesigned FaceTime app (Figure A), which now allows for group conversations—a feature that many users have been begging to see. The group conversation feature works with both video and audio and supports up to 32 people in a conversation. This feature also works with iMessage by inviting an entire group from an iMessage thread into a video or audio chat. If someone is late joining, they will be able to join at their leisure by tapping a join button in iMessage. Apple demoed the group conversations feature in FaceTime at WWDC ’18, but the feature has been cut from the 12.0 release of iOS; Apple noted this feature will be released in the fall of 2018 now.
Notifications also received improvements in iOS 12. You can turn on quiet delivery for notifications from particular apps, or turn off notifications for an app altogether. Quiet notifications are delivered to the Notification Center but don’t play a sound, present a banner, or appear on the Lock Screen; this notification management can be done in real time by selecting a notification from the Notification Center or Lock Screen. The ability to group notifications by application will be a big improvement for users who utilize apps that generate a lot of notifications.
If you use your iPhone as an alarm clock, notifications received while in Do Not Disturb mode will not be presented to you until the morning. Another improvement makes it easier to use Do Not Disturb: You can enable the mode for one hour, until the evening, or based on calendar events (e.g., you might enable Do Not Disturb during a meeting and then disable it after the meeting).

What are the new security features in iOS 12?
Apple’s mission to protect user privacy can be seen in the company’s attention to detail and customer privacy in its products.
In previous versions of iOS, Apple added the ability to get notifications when apps want to access system features including camera, microphone, location services, and more. With iOS 12, Safari will protect your privacy by ensuring that websites cannot track your online activity without your permission. Apple prevents advertisers from collecting unique characteristics that can be used to target your devices for online ads.
Apple also makes it easier to use two-factor authentication (2FA) and temporary passwords via SMS. When your device receives a 2FA or temporary password via SMS, it will be remembered by AutoFill so you won’t have to copy and paste the code into the text field in Safari.

In addition, iOS will automatically flag any password that is being reused on websites and in apps so that you don’t run into an issue where one account being compromised causes multiple accounts to become compromised.
What’s ARKit, and how can I experience it?
ARKit is Apple’s augmented reality toolkit for developers, and it was introduced at WWDC 2017. Over the past year, Apple has been working to improve augmented reality on iOS, and using the advanced sensors on the device, has one of the best AR experiences available on mobile devices.
With ARKit 2 in iOS 12, Apple gives developers even more possibilities when it comes to creating augmented reality apps. ARKit 2 lets multiple people experience AR simultaneously on their own devices in the same room, allowing for interactive experiences like games (Figure B).
In addition, a new file format for AR objects presents new options for shared experiences, like being able to share the current map between multiple devices at the same time, giving users a unique experience for multi-player augmented reality in games and other applications. At WWDC 2018, Apple demoed AR objects inside of the Apple News app and showed how it can provide more depth to stories.
What is Screen Time, and how can I use it?
Screen Time (Figure C) is Apple’s attempt to lessen the impact of technology on our lives. Screen Time will track the apps you use frequently and show where you spent most of the time on your devices. In addition, it lets you set time limits for certain apps.
Once a counter has been reached, the app time limit can be extended, but Apple will still prompt you to not use the app. This feature is great for people to use for self-control of their device usage, and shows that Apple is working to help improve our mental lives as well.
In terms of parental controls, if you have children, this app can be used to set the device limits for certain apps as well, and can be managed from a parent’s device.
When was iOS 12 released?
Apple announced iOS 12 at WWDC 2018 on June 4, 2018. iOS 12 was in beta from June 2018 through September 16, 2018. The public release of iOS 12 was made available on September 17, 2018.
How can I get and install iOS 12?

Or, you can install iOS 12 without connecting your device to iTunes by navigating to Settings | General | Software Update and following the prompts for installation.
