Description

Xcode provides everything developers need to create great applications for Mac, iPhone, and iPad. Xcode 4 has been streamlined to help you write better apps. It 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. 

Xcode runs on OS X Lion and includes the Xcode IDE, Instruments, iOS Simulator, the latest Mac OS X and iOS SDKs, and hundreds of powerful features:

Innovative tools to help you create great apps
• Interface Builder is fully integrated as a design canvas within the Xcode IDE
• The Assistant shows files related to what you're editing, such as the header, superclass, or controller
• The Version editor shows a live source code comparison through Git or Subversion history
• Live Issues display errors as you type, and Fix-it can correct the mistakes for you
• Apple LLVM compiler is embedded within the IDE with support for Objective-C, C, and C++
• The new LLDB debugging engine is faster and more memory-efficient than GDB
• Instruments adds System Trace and new iOS instruments including OpenGL ES

Streamlined interface that is faster and easier to use
• Design your interface side by side with the backing source code
• Create connections from your GUI design directly to the related source code
• Use tabs to organize your workspace, or double-click to open files in a new window
• Schemes let you customize exactly how your app will build, run, profile, and deploy
• Debugging and console views slide in without disturbing your place in the editor

Professional editor keeps you focused on your code
• Click the Jump Bar at the top of the editor to instantly go to another file
• View message bubbles to see errors, warnings, and other issues right beside the code
• Use the ribbon on the left of the editor to fold your code, or highlight scope

Embedded Apple LLVM technology finds and fixes bugs for you
• Analyzer travels countless code paths looking for logical errors before they become bugs
• Live Issues underlines coding mistakes as you type with no need to build first
• Fix-it can confidently correct mistakes for you with just a keystroke
• Code completion for Objective-C, C, and C++ is incredibly fast and accurate

Instruments for visual performance analysis
• 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

What's New in Version 4.3

Xcode is now distributed as an application, rather than as an installer. This change enables Xcode to be updated directly from the Mac App Store.

• Includes SDKs for Mac OS X 10.7 Lion and iOS 5
• New code signing workflow supports signing OS X apps with Developer ID
• Adds installation of command-line tools to the Downloads preference pane
• Open Developer Tool menu launches Instruments, File Merge, and other tools
• ARC migration tool converts both retain/release and garbage collected code
• Additional bug fixes and stability improvements

To test or deploy applications on an iOS device you must be a member of Apple's iOS Developer Program.  To submit your Mac or iOS apps to the App Store you must be a member of the Mac or iOS Developer Program.  Some features may require Internet access.

A lot to like in the 4.3 release!

I have found a lot to like in the Xcode 4.3 release, and I'd finally ready to move away from using Xcode 3 all together...if only I could use my IB plugins! Arg!

One of the best things is that code signing is finally very usable when you have more than one set of keys/certificates, which Xcode able to correctly find the signing profile and keys needed even when using multiple keychains. Hurray!

I still have issues with the way Xcode 4 makes switching debug/release/etc builds much more difficult and time consuming than it should be, all of the wasted screen space (large borders, etc) and not being able to use it in a vertical orientation (due to it's non-changeable landscape layout), but these are minor issues I would have not taken a star off for (since it is a free app).

The removal of support for Interface Builder plugins however, is a killer. These provide so much in terms of a developer's ability to enhance their workflow and simplify user interface design/coding/etc.

That said, the v4.3 release shows some nice progress and gives me hope that Apple will provide solution for IBPlugins and customizing the Xcode UI in an upcoming release.

Good improvement, that it is app, not installer

Good job at first view, All old projects work with it. Very good that I should not save installer nowadays. Thanks.

Awesome Update!

Much better than before. While debugging QtWebKit, Xcode 4.2 would go all the way up to consuming 4+ GB of RAM. The new release (4.3) does it with 1.8GB!

Command clicking on C++ symbols would used to take you to the header file. Now it correctly takes you to the implementation file as you would expect.

Xcode after having indexed my large project is taking only a fraction of RAM that it used to take. They really have squashed some bugs here :-)
