Apple Xcode For Mac

Xcode provides everything developers need to create great applications for Mac, iPhone, and iPad. Xcode has unified user interface design, coding, testing, and debugging all within a single window. The Xcode IDE analyzes the details of your project to identify mistakes in both syntax and logic, it can even help fix your code for you. Overview Xcode consists of a suite of tools that developers use to build apps for Apple platforms. Use Xcode to manage your entire development workflow—from creating your app to testing, optimizing, and submitting it to the App Store.

Learn about the key features available in Xcode, the integrated development environment for building apps for Mac, iPhone, iPad, Apple Watch, and Apple TV. For detailed information on updates in the latest released versions, including each beta release, see the Xcode Release Notes.

Xcode 11

Xcode 11 includes Swift 5.1 and SDKs for iOS 13,tvOS 13,watchOS 6, and macOS Catalina 10.15

This release adds many features to bring your apps to even more Apple platforms. SwiftUI is an innovative new user interface framework with a declarative Swift syntax that is easy to read, and natural to write. Amazing new preview tools let you manually type SwiftUI code, or modify the UI with rich design tools, with code and design always in sync. Get a head start on your Mac app by selecting the “Mac” checkbox in the project settings of your existing iPad app. And with support for Swift packages in Xcode 11, you can share code among all your apps, or make use of packages created by the community.

SwiftUI

Xcode 11 includes SwiftUI, a new Swift framework and accompanying design tools that empower a whole new way to build user interfaces. Design tools in Xcode make it as easy as drag-and-drop to construct or edit your interface, all while instantly editing the exact same Swift code file you can also edit by hand. Xcode is constantly running your real app interface live to see how it behaves directly in the design canvas, or you can instantly preview your app on an attached device.

SwiftUI includes:

Design tools read and write the same code you edit by hand for a single source of truth
Declarative syntax defines your user interface as easy-to-read Swift code
Animations are built using simple commands that describe the action you want to see
Library of controls and modifiers make it easy to design and build complex interfaces
Share common UI code across all Apple platforms, and add custom experiences for each OS
Previews show an exact rendering across various device types and accessibility settings
Interact with your interface live in the design canvas, or on an attached device
Hot-swap your edits into a live view of your app to instantly see and interact with changes

SwiftUI requires iOS 13,watchOS 6,tvOS 13, or macOS Catalina. To use the SwiftUI design canvas Xcode 11 must running on macOS Catalina.

Bring your iPad app to the Mac

It is easy to bring your existing iPad app to millions of Mac users. When you click a single checkbox Xcode can transform your iPad app into a true native Mac app that performs great.

Clicking a checkbox in your iPad project adds a native Mac app, built with the macOS SDK
Use a single code base for iPhone, iPad, and Mac versions of your app, and customize parts of your app for Mac
Add new SwiftUI code to the existing shared UIKit code
Submit to the Mac App Store directly from Xcode, or notarize for outside distribution

With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line of code.

Designed for macOS Big Sur.

Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons. The navigator defaults to a larger font that’s easier to read, while giving you multiple size choices. New document tabs make it easy to create a working set of files within your workspace.

Document tabs.

The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The navigator tracks the open files within your tabs using strong selection.

Navigator font sizes.

The navigator now tracks the system setting for “Sidebar icon size” used in Finder and Mail. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.

Code completion streamlined.

A new completion UI presents only the information you need, taking up less screen space as you type. And completions are presented much faster, so you can keep coding at maximum speed.

Redesigned organizer.

Web Development In Xcode

An all-new design groups all critical information about each of your apps together in one place. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers.

SwiftUI

SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls.

Universal app ready.

Xcode 12 is built as a Universal app that runs 100% natively on Intel-based CPUs and Apple Silicon for great performance and a snappy interface.* It also includes a unified macOS SDK that includes all the frameworks, compilers, debuggers, and other tools you need to build apps that run natively on Apple Silicon and the Intel x86_64 CPU.

Updated automatically

When you open your project in Xcode 12, your app is automatically updated to produce release builds and archives as Universal apps. When you build your app, Xcode produces one binary “slice” for Apple Silicon and one for the Intel x86_64 CPU, then wraps them together as a single app bundle to share or submit to the Mac App Store. You can test this at any time by selecting “Any Mac” as the target in the toolbar.

Test multiple architectures.

On the new Mac with Apple Silicon, you can run and debug apps running on either the native architecture or on Intel virtualization by selecting “My Mac (Rosetta)” in the toolbar.

Multiplatform template

New multiplatform app templates set up new projects to easily share code among iOS, iPadOS, and macOS using SwiftUI and the new lifecycle APIs. The project structure encourages sharing code across all platforms, while creating special custom experiences for each platform where it makes sense for your app.

Improved auto-indentation

Swift code is auto-formatted as you type to make common Swift code patterns look much better, including special support for the “guard” command.

Developer Xcode Download

StoreKit testing

New tools in Xcode let you create StoreKit files that describe the various subscription and in-app purchase products your app can offer, and create test scenarios to make sure everything works great for your customers — all locally testable on your Mac.
