What Is New In iOS 11?

• The one-handed keyboard features, with "Flick" option for typing numbers and symbols more quickly on the iPad.
  
  
• Notes app includes searchable handwriting and document scanning.
  
  
• Now, iOS includes indoor maps for malls and airports; along with lane guidance, speed limit info etc.
  
  
• MusicKit on iOS lets users play Apple Music and their local music library natively from your apps and games. When a user provides permission to their Apple Music account, the app can create playlists, add songs to their library, and play any of the millions of songs in the Apple Music catalog. If your app detects that the user is not yet an Apple Music member, you can offer a trial from within your app.
  
  
• AirPlay lets the user stream content to displays and audio systems with AirPlay. Using Media Player APIs that support AirPlay, users can play content from an iOS device on a high-definition TV using Apple TV or to an AirPlay-enabled sound system.
  
  
• Business Chat is a powerful new way for businesses to connect with customers directly in messages. Customers can find your business and start conversations from Safari, Maps, Spotlight, and Siri. The following customer service platforms have already been integrated with Business Chat — LivePerson, Salesforce, Nuance, and Genesys.
  
  
• iOS 11's Messages app has been updated with several new features including a new app drawer which contains stickers, the new Apple Pay peer-to-peer feature that lets you pay contacts via iMessage, and lots more.
  
  
  
  
• Portrait Mode and Live Photos have been improved with new capabilities in the camera app. Photos and videos also take up less space through the adoption of new HEIF and HEVC formats.
  
  
• Do Not Disturb mode for driving, muting notifications while a vehicle is in motion
  
  
• A new App Store is there in iOS 11 with two distinct sections for apps and games. You'll see new Collections, a Daily List centered around a particular theme, and even tutorials that show you how to do particular things in the new apps.

• One of the signature features of Google Now is finally coming to the iOS: When you type in iOS 11, the keyboard will suggest words you may have recently viewed on your phone — from your Messages app, for example, or Safari.

• Improved data tracking: Within the Mobile Data section of the Settings app, a bunch of new options and menus have been added. There's a new addition to iOS that'll make it much easier to manage mobile data without the need to download a third-party app from the App Store. Now, the user will be able to find out how much data they have used and how much they have left in the Settings app. It will allow users to even change data plan from within the Settings app. This feature, however, will have to be compatible with the service provider.

Apple is introducing new APIs mainly CoreML and ARKit for better app and gaming experience. CoreML provides machine learning tools to developers, while ARKit lets developers build complex and richly detailed augmented reality features into their apps. Let us explore these two features in detail to understand what they are capable of.

CoreML

Core ML delivers blazingly fast performance with easy integration of machine learning models enabling you to build apps with intelligent new features using just a few lines of code. It lets developers integrate a broad variety of machine learning model types into any app. In addition to supporting extensive deep learning with over 30 layer types, it also supports standard models such as tree ensembles, SVMs, and generalized linear models. Because it’s built on top of low-level technologies like Metal and Accelerate, Core ML seamlessly takes advantage of the CPU and GPU to provide maximum performance and efficiency. It is possible to run machine learning models on the device so data doesn't need to leave the device to be analyzed.

Supported features include face tracking, face detection, landmarks, text detection, rectangle detection, bar code detection, object tracking, and image registration.

• Natural Language Processing
  The natural language processing APIs in Foundation use machine learning to deeply understand text using features such as language identification, tokenization, lemmatization, part of speech, and named entity recognition.
  
  
• Models
  Developers can build apps with the ready-to-use Core ML models like
  
  
  • MobileNets - is based on a streamlined architecture that has depth-wise separable convolutions to build lightweight, deep neural networks. Detects the dominant objects present in an image from a set of 1000 categories such as trees, animals, food, vehicles, people, and more.
  • Squeezenet - Detects the dominant objects present in an image from a set of 1000 categories such as trees, animals, food, vehicles, people, and more. With an overall footprint of only 5 MB, SqueezeNet has a similar level of accuracy as AlexNet but with 50 times fewer parameters.
  • Places205- GoogLeNet: Detects the scene of an image from 205 categories such as an airport terminal, bedroom, forest, coast, and more.
  • Other models available include ResNet50, Inception v3 and VGG16 or use Core ML Tools to easily convert models into the Core ML format

ARKit

iOS 11 introduces ARKit, a new framework that allows developers to easily create unparalleled augmented reality experiences for iPhone and iPad. By blending digital objects and information with the environment around you, ARKit takes apps beyond the screen, freeing them to interact with the real world in entirely new ways. ARKit comes handy in the following apps and features

• TrueDepth Camera
  iPhone X and ARKit enable a revolutionary capability for robust face tracking in augmented reality apps. Using the TrueDepth camera, an app can detect the position, topology, and expression of the user’s face, with high accuracy and in real time, making it easy to apply live selfie effects or use facial expressions to drive a 3D character.
  
  
• Visual Inertial Odometry
  ARKit uses Visual Inertial Odometry (VIO) to accurately track the world around it. VIO fuses camera sensor data with CoreMotion data. These two inputs allow the device to sense how it moves within a room with a high degree of accuracy, and without any additional calibration.
  
  
• Scene Understanding and Lighting Estimation
  With ARKit, iPhone and iPad can analyze the scene presented by the camera view and find horizontal planes in the room. ARKit can detect horizontal planes like tables and floors, and can track and place objects on smaller feature points as well. ARKit also makes use of the camera sensor to estimate the total amount of light available in a scene and applies the correct amount of lighting to virtual objects.
  
  
• High-Performance Hardware and Rendering Optimizations
  ARKit runs on the Apple A9, A10, and A11 processors. These processors enable fast scene understanding and allow creating detailed and compelling virtual content on top of real-world scenes. ARKit can be optimized for Metal, SceneKit, and third-party tools like Unity and Unreal Engine.

Other than the features listed above, the iOS 11 has some more fancy surprises up its sleeves. It makes the need for saving passwords for WiFi network obsolete. So, now if you need a WiFi password for a given network, all that is needed is to find someone who is already using the network and hold the device near theirs. The password will be transferred instantly. iOS11 allows customization of a new device way easier by allowing import of all your settings, preferences, and iCloud Keychain passwords from the old one by holding it close to an iOS device you already own
