MultitaskingHow to Create an Xcode Project for an iPad App. By default, Xcode is downloaded to /Developer/Applications, where you can track it down to launch it. When you launch Xcode, you see. 2 Select Create a New Xcode Project from the Welcome screen (or choose File→New Project) to create. I'm an iOS and Mac developer. I use Xcode all day with Swift and Objective-C. I recently had the need to work on a small website project. This isn't what I normally do. I use TextMate as my single-file text editor, alongside Xcode. But I found the app very annoying for working in a web project with multiple files.

Machine LearningWith on-device model training and a gallery of curated models, there's never been a better time to take advantage of machine learning. Core ML seamlessly takes advantage of the CPU, GPU, and Neural Engine to provide maximum performance and efficiency, and lets you integrate the latest cutting-edge models into your apps. The Create ML app lets you build, train, and deploy machine learning models with no machine learning expertise required.
Augmented RealityRun Xcode On IpadARKit delivers an incredible awareness of people with the ability to integrate human movement into your app, the People Occlusion feature that lets AR content realistically pass behind and in front of people in the real world, and much more. RealityKit — Apple's rendering, animation, physics, and audio engine — powers Reality Composer and can power your own AR apps, allowing you to seamlessly integrate virtual objects into the real world.
Desktop-class Browsing with SafariSafari on iPad supports the latest web standards and automatically adapts websites and web apps to touch, delivering a rich browsing experience with blazing-fast performance, industry-leading security, and modern desktop features.

Building for iPad ProiPad Pro lets you deliver faster, more responsive experiences like never before. The all-screen design goes from edge to edge. Face ID works seamlessly in portrait or landscape. The A12X Bionic chip outperforms the vast majority of portable PCs, runs pro apps, and enables stunning augmented reality experiences. And with support for accessories like the second-generation Apple Pencil and Smart Keyboard Folio, iPad Pro represents the biggest change to iPad ever.
Face ID

This secure way to unlock, authenticate, and pay lets users quickly access your app with just a glance. The TrueDepth camera projects and analyzes more than 30,000 invisible dots to create a facial map that is encrypted and protected by the Secure Enclave on the device.
For details on user authentication, see the Human Interface Guidelines.
A12X BionicThe A12X Bionic chip with the Neural Engine is the smartest, most powerful chip we've ever made, and it's been designed specifically for iPad Pro. The A12X Bionic delivers faster CPU performance than the majority of portable PCs. The Apple-designed 7-core GPU, along with architectural enhancements and memory compression enable the GPU to perform up to 2x faster. And the 8-core Neural Engine, which runs five trillion operations per second, is dedicated to highly efficient, powerful machine learning, enabling all-new experiences.

How To Build Ipad Apps With Xcode TutorialUI OptimizationTake advantage of the all-screen design of the 11-inch iPad Pro and 12.9-inch iPad Pro (3rd generation) by building your app with the iOS 12.1 SDK or later and making sure it appears correctly with the display's rounded corners and home indicator.
Run and Test in Simulator. Make sure your apps take advantage of the edge-to-edge Liquid Retina display by respecting safe areas and supporting adaptive layouts. Read the updated Human Interface Guidelines, download the latest version of Xcode, and test your app in Simulator.
Enable full screen native resolution. Your app will run in Full Screen Display Mode on iPad Pro if your project's base SDK is set to iOS 12.1 or later and you have a Launch Storyboard.
Verify all parts of your app. Make sure that your UI displays correctly and no elements are mispositioned, overlapping, incorrectly scaled, or clipped. If you discover issues, use the safe area guides and layout margins to correctly position UI elements.
Bring Your iPad App to MacGet a huge head start on creating a native Mac app based on your existing iPad app. Your Mac and iPad apps share the same project and source code, so any changes you make translate to both platforms. And your newly created Mac app runs natively, utilizing the same frameworks, resources, and even runtime environment as apps built just for Mac.
Sidecar on macOS CatalinaUsers running macOS Catalina can use iPad as a secondary display alongside Mac and draw with Apple Pencil on iPad. There's no need to make any adjustments to Mac apps — they just work.
There are some features of iOS apps that don't work from the iOS simulator. Maybe you want to test how your application works with the device camera or send an SMS message from your application. For these examples and more you'll need to test and debug your app using a real device.
This post will walk through how to run the Xcode simulator on your iPhone or other iOS device and show you how to fix some common errors you'll see along the way.
How to select your iPhone as the 'Simulator' DeviceSimulator is in quotes here since this will create an actual app on your phone; it's no longer a simulation. Open up a project in Xcode and click on the device near the Run ▶ button at the top left of your Xcode screen.
Plug your iPhone into your computer. You can select your device from the top of the list.
Unlock your device and (⌘R) run the application. You'll see Xcode install the app and then attach the debugger. The application should pop up on your phone.
Troubleshooting Common ErrorsThe first time I tried to connect my iPhone to Xcode it didn't work. According to my best friend, Stack Overflow, I'm not the only one who has had issues. Let's share the fixes to some common errors you might encounter.
'Signing Requires a Development Team'
Xcode requires that you've connected a Team to your project in order to run the simulator on a device. You can do this from the 'General' tab of your Project Settings. As of Xcode 7 this can be any Apple ID.
Open the Team menu that currently says 'None' and select your team. If you don't have a team, select 'Add an Account…' and create one with your Apple ID.
Xcode claims your device is locked when it isn'tThis fun bug has been happening since at least Xcode 6. There are a lot of potential solutions in this Stack Overflow post. Here's what worked for me:
Unplug your iPhone
Reset Location & Privacy on your iPhone. Found under Settings >> General >> Reset
Plug in your iPhone
Hit Trust when prompted to Trust This Computer
You can learn more about how trusting computers works from Apple's support.
'iPhone is Busy'The unsatisfying answer for this one is to just wait.
If you don't have a sword fighting partner, you can try the following:
Unplug your device
Restart both Xcode and your iPhone
Plug in your device
That worked for me, but a lot of folks had luck with 'Solution #3' from this Stack Overflow post.
