iOS 12, the latest version of iOS, was released to Apple devices on September 17, 2018. And its preview started to enter the eye-sight of the public at the keynote event at the WWDC 2018 (Worldwide Developers Conference) on June 4. iOS updates were originally introduced in a beta or pre-release testing version, and the official version follows after that.
The first iOS 12 developer beta was available after the WWDC keynote (we have now reached the sixth beta), but it is only for registered developers as the name suggests. The public beta version for the public is available for download on June 25. And the final public release of iOS 12.0 took place in the fall - September 17, 2018.
iOS 12 is able to speed up the things you do every day on your iPhone or iPad, providing your a faster and more responsive experience. For example, when you launch camera, load an app, or type with the keyboard, it reacts faster than ever if you are doing it a lot on your device. Apps launch up to 2X faster under heavy workload; the keyboard displays up 50% faster and sliding to Camera can be up to 70% faster. This performance improvements happen on both new and old devices as long as they are supported by iOS 12.
The performance improvement is to optimize the system when under load, Apple said. And also iOS 12 boosts performance as needed and then lowers it when needed to extend battery life. According to WWDC, Apple has optimized peak load requirements to better distribute access the processing power inside the device. The application is about to double its boot speed under load after upgrading to the newest iOS 12, even though it is an old iPhone 5s and iPod Air.
In iOS 12, FaceTime supports video and audio for up to 32 people at a time. With Group FaceTime, all participants can be seen in the tiled view, and the tile of the person who's speaking will automatically grow bigger, so you will never lose track of the conversation. You can also double-tap on the person you want to view using the Focus View.
You can launch Group FaceTime directly from a group thread in Messages, or you can also join an on going Group FaceTime at any time. And you can answer the Group FaceTime calls on iPhone, iPad, Mac, Apple Watch and HomePod. With two options, you can only join a chat with audio instead of video. Besides, Group FaceTime call sends a silent, no-ring notification to participants who can tap to join. FaceTime has been more deeply integrated into the Messages, so you can start a FaceTime call in either an individual chat or group chat.
Also, FaceTime includes the same Effects camera introduced in Messages, allowing you to access Animoji and Memoji, filters, stickers, etc. when you are in FaceTiming.
Both of Animoji and Memoji are available for Messages and FaceTime in iOS 12. As for devices with a TrueDepth camera system, Animoji in iOS 12 comes with new features, such as tongue detection and better face tracking. Through tongue detection, Animoji can stick out a tongue and also choose to detect blinks.
Animoji recordings can now last up to 30 seconds, which is 10 seconds higher than in iOS 11, so you can record longer Animoji messages. And there are also new Animoji options available, including Ghost, Koala, Tiger and T-Rex, as well as a new customizable Animoji experience called Memoji.
Memoji is a new type of customizable Animoji, which enables you to create a Memoji to fit your personality and mood. You can choose skin color, hair color, hair style, eye color, eyebrows, nose, freckles and facial hair, accessories and headwear. There is no limit to the number of Memoji you can create, so you can add more than one for each look you want to express.
ARKit 2.0 makes some other improvements, such as better 3D object detection, face tracking, realistic rendering, persistent experiences and shared experiences. Apple designed a new file format called USDZ, which retains 3D graphics and animations in iOS 12. This means that you can see augmented reality assets in Safari, Mail, Messages and more.
And a new AR app called Measure is available in iOS 12, which allows you measure real-world objects just by pointing your device's camera at them. For example, by tapping two points on a table using your iPhone's camera, you can see the measurement for the table's length and width in real word. What's more, when you are viewing a rectangular object such as a book, the system will automatically recognize the shape and offer you the measurements of the book.
Screen time is a new feature built into the Settings app in iOS 12 and it aims at helping you suppress iPhone addiction and achieve a healthier balance between gadgets and life. It can analyze the time you spend on your device and each app and provides a summary of weekly usage habits to help you set a fixed time limit for each app. You will be notified when time's up. Of course, you can ask for more time if you want.
Other features in iOS 12 for combating iPhone addiction:
- Do Not Disturb: darken the display and hide all notifications on the lock screen while sleeping.
- Group Notifications: Allow users to combine notifications with swipes and manage notifications from the lock screen.
- Deliver Quietly: Transfer all notifications to your control center with no sound prompts and read notification badges.
- Allowance: Improves parental control of your child's use on an app.
