Xcode provides everything developers need to create great applications for Mac, iPhone, and iPad. Xcode brings user interface design, coding, testing, and debugging all into a unified workflow. The Xcode IDE combined with the Cocoa and Cocoa Touch frameworks, and the 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, iOS Simulator, the latest OS X and iOS SDKs, and hundreds of powerful features:

Innovative tools help you create great apps
• Swift is a revolutionary new 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-it can correct the mistakes for you

Swift is an all new programming language for Cocoa and Cocoa Touch
• 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
- 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
• 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 underlines 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 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 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 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. Continuous integration features require a current version of OS X Server. Some features may require Internet access.

What's New in Version 6.1.1

Includes SDKs for OS X 10.10 Yosemite, OS X 10.9 Mavericks, and iOS 8.1

• Fixes common causes of SourceKit crashes when working with Swift

Not quite ready for prime time...

I can’t speak for ObjectiveC or C++ development, but as far as Swift development goes, this just isn’t a finished product. The autocomplete is good, but highly aggressive, and it often feels like it’s getting in the way of basic coding. Sourcekit also has its own share of issues; it can have a tendency to crash, or to randomly lag. It takes a long time for it to unmark errors, and quite a few times it has failed to identify line numbers corresponding to errors, forcing me to sift through the compiler errors sourcekit spits out.

Also, when I opened the template for an iOS Swift OpenGL ES game, what I found was a file comlpetely commented out, with a heading saying that OpenGL ES in Swift was experimental. That doesn’t exactly seem polished.

The worst offense of all, though, is refactoring; or rather, the lack of it. Currently refactoring, one of the most basic functions of a modern IDE, and what programmers expect to have in their development environment, is not supported for Swift. With the lack of such a basic feature, I can’t imagine how large-scale projects can be completed efficiently.

I like this IDE and I think it has potential, but it (and the current Swift implementation) got pushed out the door far too fast.

Excellent IDE but a couple issues sometimes when editing

Xcode is a stellar IDE; it completely destroys Eclipse and NetBeans and all other IDEs I’ve used. I only have a couple issues, however:

1.) Sometimes when editing .swift files, there is an intense amount of lag; often it takes 5-6 seconds for each letter. I don’t know if this is related to SourceKit or whatever and it doesn’t happen that often, but when it does it makes me want to pull my hair out.

2.) Xcode’s autocomplete is so good that often I (as well as many other developers I know) get incredibly dependent on it, especially since many of the method names are far too long to memorize. Very rarely, however, the autocomplete just completely dies and we’re left stranded. I have to close all Xcode related processes (iOS simulator, etc.) and quit Xcode completely, reopen it, and open up my project again to fix it, which is very inconvenient and disrupts the flow of app development.

Please fix these two issues and I will update this review ASAP to 5 stars.

Less revolution, more evolution, please!

Xcode has long been pretty muich the best development environment out there. However, over the last couple of major releases, Apple has been so focused on massive, revolutionary changes that they leave little annoying problems around forever, and other, more serious bugs, gradually get worse over time. If Apple spent one major release focusing solely on locking own all the glitches and problems, Xcode would be the best software development system you can get. As it stands, it’s just really good (the amount of good depending on what you’re doing with it).
