iPhone XS, iPhone XS Max, and iPhone XR feature a trio of edge-to-edge displays paired with A12 Bionic and the next-generation Neural Engine. A12 Bionic is the smartest and most powerful chip ever in a smartphone, and is designed for performance in mind with Core ML, ARKit, Metal, and more. And now Face ID works even faster than before to securely and privately unlock, authenticate, and pay.
Edge-to-Edge Displays
The Super Retina displays on iPhone XS and iPhone XS Max support High Dynamic Range (HDR) with a 1,000,000 to 1 contrast ratio, wide color support, and the best color accuracy in the industry. iPhone XR introduces the Liquid Retina display — the most advanced LCD in a smartphone with industry-leading color accuracy. These edge-to-edge displays precisely follow the curves of the design, clear to the elegantly rounded corners, so your apps look incredible. And with wider stereo playback, your apps will now have immersive sound to match.
Optimize your UI.
If you’ve already updated your app for iPhone X, simply build your app with the iOS 12 SDK and test in Simulator, included with Xcode 10, to make sure it looks great on iPhone XS, iPhone XS Max, and iPhone XR. To update your app for these new devices, follow the steps below.
Run and Test in Simulator. Make sure your apps take advantage of the edge-to-edge display by respecting safe areas, supporting adaptive layouts, and more. Read the updated Human Interface Guidelines, download the latest version of Xcode 10, and test your app in Simulator.

Enable full screen native resolution. Your app will run in Full Screen Display Mode on iPhone X, iPhone XS, iPhone XS Max, and iPhone XR if your project’s base SDK is set to iOS 11 or later and you have a Launch Storyboard or iPhone X launch image.
Verify all parts of your app. Make sure that your UI displays correctly and no elements are mispositioned, overlapping, incorrectly scaled, or clipped, especially in landscape mode. If you discover issues, use the safe area guides and layout margins to correctly position UI elements.
If only parts of your app run in Simulator — for example, if it mostly uses UIKit, but has camera integration — you should test as much of your UI as possible by commenting out views that Simulator doesn’t support.
Xcode 10.1
Download the latest version of Xcode from the Mac App Store, which includes the latest SDKs for iOS 12 and the iPhone X simulator.
A12 Bionic
This year’s chip is faster, more efficient, and equipped with the next-generation Neural Engine. The Apple-designed GPU has a fourth core added, along with architectural features like tessellation and multi-layer rendering. The combination of the extra GPU core, architectural enhancements and memory compression enable the GPU to perform up to 50% faster. And the 8-core Neural Engine is dedicated to highly efficient, powerful machine learning, enabling all-new experiences.
Machine Learning
Experience seamless integration of Core ML 2 and Metal 2 on the new A12 Bionic. Amazingly fast on-device machine learning enables more intelligent, high-performance apps, all while keeping user data private. Apps automatically take advantage of the processing power of the next-generation Neural Engine on A12 Bionic with smart compute selection. Utilize new API features including image blocks, tile shading and threadgroup sharing, along with optimizations like batch predictions, quantization, and flexible image sizes.
Augmented Reality
The next-generation Neural Engine enables ARKit to detect planes faster and in more challenging environments, while making tracking more robust and power efficient. ARKit 2 also enables powerful new features like shared experiences for multiplayer capable apps and 3D object detection to trigger AR experiences from real world objects. Using the TrueDepth camera, your app can detect the position, topology and expression of the user’s face, all with high accuracy and in real time. This makes it easy to apply live selfie effects or use facial expressions to drive a 3D character.

IPhone SDK 3.0 has a lot of nifty new features. One feature I want to use is to send email without exiting my application. In the past, I have to use UIApplication openURL: to launch the Mail application. But once I do that, the user is gone, gone, gone.In SDK 3.0, there is a MFMailComposeViewController class that allows me to bring up a Mail Composer view. When the user is done with the email and tap Send, user is back in my application. Can it be cooler than that?Yes, of course. Using the MFMailComposeViewController class, I can also preload the body with an attachment.
So, if my application generates a graphical chart, a CSV file, a sound file, etc., I can attach it to the email that is being sent.The (you may need to be logged into Apple’s Developer Connection to access this link) goes into the nitty gritty details on how to use this new class. Definitely dig into the sample code.My first question was does that mean that my application is now limited to iPhone OS 3.0 users? I don’t want to do that as it excludes a large segment of the population who did not bother to upgrade (even though the upgrade is free on the iPhone). Here’s the cool part.
You don’t have to exclude the pre-3.0 users. The MailComposer sample application goes into the details of how to do that. You build the application with SDK 3.0. You target to iPhone OS 2.2.1 (or whatever version you want). You write your code to check for existence of certain 3.0 framework before using them, and provide a graceful degradation path for pre-3.0 users. In setting up the Frameworks for your build target, you set the role of the 3.0 framework used in your application to weak such that application will launch even if some of the frameworks are missing.Step 4 above is the important part. If you don’t do that, your application will fail to launch on pre-3.0 devices.
The following is the screen capture for where to set a framework’s role to weak. Xcode example of where to set a Framework to WeakAs for testing, if you have the luxury of a rackful of devices running different OSes, by all means test on all of them. The other option is to test on pre-3.0 OSes using the iPhone Simulator. The way to do that is first build and test by setting Xcode to Simulator 3.0 setting. This leaves a 3.0 version on your iPhone Simulator. Then from the iPhone Simulator men, choose Hardware Version and select 2.2.1. Then launch your 3.0 application in a 2.2.1 environment and test away.
