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 7.2.1
Xcode 7.2.1 includes Swift 2.1.1 and SDKs for iOS 9.2, watchOS 2.1, tvOS 9.1, and OS X 10.11.2 El Capitan.
Fixed in Xcode 7.2.1:
• Command line tool 'xcodebuild test' will no longer time out waiting for Simulator.app to launch
• Resolved a debugger crash that could occur in code depending on a binary Swift library or framework
• Updated the certificate used to develop Apple Wallet passes, Safari Push Notifications, and Safari Extensions
• Additional bug fixes and stability improvements
It’s working fine and normal, as a C language beginner.
I’m currently learning C in college; the professors and computer labs normally use Windows, so they use Microsoft Visual Studios as the compiler. I’m a Mac geek and I quickly learn that I can use Xcode instead; and it turns out better than expected:
-Boot up faster than Visual Studios
-I can switch from C files to C files on the left hand panel by just clicking on it; and I can run if I deactivate the other files with just two simple steps: misspleing main and unchecking Target.
-So I can run multiple C files by just doing the step listed above.
-Love the fact that it’s Mac OS X compatible.
-Simpler to use than MS Visual Studios.
That’s just my experinces, I was a ble to run some basic math programs; however, I’m still learning and have yet to construct more complex programs to really test if Xcode will keep up with me.
Another release that addresses none of the issues. Shame.
Xcode is broken. It’s full of ugly bugs, it crashes several times per day and the performance is extremely poor. It’s unusable. No amount of radars have had an effect on this and the quality trend is downwards. I’ve left many reviews here with explicit, outlined bugs and none has been fixed. New bugs keep being introduced instead. I would say this is unacceptable but what choice do we iOS/Mac OS developers have? We’re depending on this tool but it’s very poor. Why is Apple ignoring their developers? Why is Apple treating their partners with such contempt? Why is Apple so hostile to the people who make their platforms viable?
Fix this crap, Apple!!!
Crashing periodically I can handle. But, this utterly absurd constraint system really needs a re-think. Once you have a GUI design the layout part should be easy. Layout for multiple devices should also be easy. Having spent the requisite days flopping around like an angry fish I am comfortable with this Byzantien system but it’s still simply painful for folks who can’t devote unlimitied time to learning this system. Oh, and the preview doesn’t always match the simulator. I am not an expert with with Storyboard or constraints but one shouldn’t have to be in order to build simple UIs that work across 4 device types (just phones).
