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 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, open source programming language that is safe, fast, and modern
• Playgrounds are a fun way to experiment and interact with Swift code
• Interface Builder displays pixel-perfect UI for each target device and can edit at any zoom level
• 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 improve your code with just a click
• Source Control navigator makes it easy to manage code across a team

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
• Customize your interface for different devices, screen sizes, and orientations
• 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
• Refactoring makes it easy to modify the structure of Swift, Objective-C, C, and C++ code
• Hit a few keys and Open Quickly will instantly open any file within your project
• Data tips show a variable's value by hovering your mouse over the code as it runs
• Quick Look variables while debugging to see the actual color, bezier path, image, and more
• Third party app extensions can add new capabilities to the source editor

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 to automatically build and test your apps
• Analyzer travels countless code paths looking for logical errors before they become bugs

Instruments makes performance analysis beautiful
• Compare CPU, disk, memory, and GPU performance as graphical tracks over time
• Identify performance bottlenecks, then dive deep into the code to uncover the cause
• Analyze your app directly, or sample the entire system, with very little overhead
• Create custom instruments with unique visualizations to analyze your own code and frameworks

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. Some features may require Internet access.

Nice Software

I am not very good at Apple App coding, but came from Visual Studio on Windows environment. I use XCode 2 yrs ago for editing an app for first time and after few hours it feels like home to me. Though at time it is slow, but maybe I am not good to configure it or my app is like that. However, I hate updating this app using Mac App Store, it always take 2-3 download attempt to get it upgrade. Been a 5-6 GB App if you have to download 2-3 times it take time and internet bandwidth both which cost money.

in all XCode is good, app store is not ...

Too much slow.

i am using MacBook Air. ilove the coding with this using Xcode. Using xcode 8 its workig pretty fine. By rading new features in xcode 9 i did upgrade my Xcode . pretty fine and i ffeel some new wedding features like renaming a identifier by reflector is pretty good and also the simulators and wireless dibugging etc are too good. But the main thing is its bulky kernel. its takig so much memory and hangging up so many time during edditing and dont now why its compiling again and again. plz take a look on this on Macbook air and othe devices. its making me irritating. i love the apple biz of its memory and process management but this this not a good standard. Plz review , Thanks and keep improving.:-)

Lost a day’s work

I don’t know how this happened, but Xcode decided to recursively create the project folder and place copies of the entire project inside it. There must be at least 100 sub-directories under each folder with the entire project. The best thing is that Xcode decided to place all of these in a folder which wasn’t being tracked by GIT. All of the work that I was doing was recursively being placed in the folder which wasn’t tracked by GIT. An entire day’s work was lost after I switched to another branch. Apple’s worth is in billions, but what’s the point in having so much money if you can’t hire decent engineers and testers to prevent serious issues like this from happening? Start giving importance to developers the same way you give importance to users.
