Description

Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. The Xcode IDE combined with the Cocoa frameworks and Swift programming language make developing apps easier and more fun than ever before.

Xcode includes the Xcode IDE, Swift and Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features:

Innovative tools help you create great apps
• Swift is a revolutionary programming language that is safe, fast, and modern
• Playgrounds are a fun place to experiment with Swift code, displaying instant results
• Interface Builder is a graphical UI design canvas with a live preview of your app
• View debugging shows a 3D stack of all your app's UI view layers at runtime
• Assistant editors show content related to your primary task
• Live Issues display errors as you type, and Fix-its can correct mistakes for you

Swift is a powerful, modern, and fun programming language
• Safe by design, Swift syntax and features prevent entire categories of bugs
• Fast code execution and compile time are powered by the proven LLVM compiler
• Modern language features are inspired by leading research, including:
- Closures unified with function pointers
- Tuples and multiple return values
- Structs as value types that support methods, extensions, protocols
- Powerful protocols that can extend functionality throughout your codebase
- Functional programming patterns including map and filter

Interface Builder makes it easy to design your interface without code
• Storyboards let you arrange the complete flow of screens within your app
• See your custom controls rendered live within the design canvas
• Preview your interface in different screen sizes, orientations, or languages
• StackViews make it easy to reason about the layout of each section of your interface
• Create connections from your GUI design directly to the related source code

Professional editor and debugger keep your code front and center
• Hit a few keys and Open Quickly will instantly open any file within your project
• Message bubbles show errors, warnings, and other issues right beside your code
• Data tips show a variable's value by hovering your mouse over the code
• Quick Look variables while debugging to see the actual color, bezier path, image, and more

Apple LLVM technology finds and fixes bugs for you
• Analyzer travels countless code paths looking for logical errors before they become bugs
• Live Issues identifies coding mistakes as you type with no need to build first
• Fix-it can confidently correct mistakes for you with just a keystroke

Test driven development is built right in
• Use the Test Navigator to add, edit, or run unit tests or user interface tests with just a click
• Test Assistant makes it easy to edit your code and related tests, side-by-side
• Create continuous integration bots using OS X Server to automatically build and test your apps
• Monitor performance and user interface test data using OS X Server to immediately spot regressions

Instruments makes performance analysis beautiful
• Compare CPU, disk, memory, and OpenGL performance as graphical tracks over time
• Identify performance bottlenecks, then dive deep into the code to uncover the cause
• Monitor your app directly, or sample the entire system, with very little overhead

To test or deploy applications on an iOS device, Apple TV, or on Apple Watch all you need is a free Apple ID. To submit your apps to the App Store you must be a member of the Apple Developer Program. Continuous integration features require a current version of OS X Server. Some features may require Internet access.

What's New in Version 7.3

Xcode 7.3 includes Swift 2.2 and SDKs for iOS 9.3, watchOS 2.2, tvOS 9.2, and OS X 10.11 El Capitan.

New in Xcode 7.3:

• iOS and OS X playgrounds in Xcode are interactive and respond to user-generated events such as button clicks and iOS gestures
• Code completion offers more intelligent suggestions, including options based on the first letters of words within the API
• Devices window supports switching between multiple Apple Watch devices paired to a single iPhone
• Debugger automatically imports the frameworks needed when evaluating both Swift and Objective-C expressions
• View debugging adds additional inspector information, context menus, and Assistant editor options
• Static analyzer identifies more potential issues related to nullability and Objective-C generics

New in Swift 2.2:

• Swift toolchains downloaded from Swift.org can be easily selected in the updated Components tab in Preferences
• New #file, #line, #column, and #function expressions
• Improvements to the standard library including new removeFirst() and removeLast() methods on slice types
• Conditional build option can compile specific code blocks within the same file based on current Swift version
• New #selector expression to reference the Objective-C selector of a method
• Failable class initializers can return 'nil' before calling the superclass initializer
• Improved compile-time diagnostic messages
• Deprecations to syntax such as ++, --, and C-style for loops in preparation for the future Swift 3 release

Xode 7.3 update

Not able to update Xcode 7.3. After clicking Update, it shows buffering symbol for a long time. But no progress in updating the Xcode. Looks like it is serious issue. It will impact developers, who are using iOS 9.3 and above. Apple team please take care of this ASAP.
