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 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 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
• 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
• 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
• 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 using macOS Server to automatically build and test your apps
• Monitor performance and user interface test data using macOS Server to immediately spot regressions
• Analyzer travels countless code paths looking for logical errors before they become bugs

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 macOS Server. Some features may require Internet access.

Slow and pretty much unusable

Nishanth Rao

Xcode is one of the worst software I have ever used, it is supposed to be a single point development tool for Mac and iOS devices but making it work is like teaching an elephant to tap dance.

If I want to compile and run an application for iOS platform, the amount of time taken start the iPhone simulator is almost 15 - 20 minutes and I will have to try building & running it a couple of times on Xcode so that it can run properly in the simulator..Its an absolute nightmare, and if by any chance you open any other application the whole thing start crawling without allowing any other work to be done in the system.

Playgrounds never have worked, just open a new playground and the whole systems starts crawling, it keeps showing the message as Running and nothing happens and after a while it shows some message telling that it could not load the libraries.. Swift playgrounds on iPad runs better than on a Mac.

If I cannot run Xcode and do some development the MBP is just an expensive paperweight. Correction, it is JUST an expensive PAPERWEIGHT considering I cannot use XCODE at all. Its absolutely frustrating and I don’t see any improvements from Apple with regards to this.. What a waste of time and money.

I use a MBP mid 2012 with initial specs.. Thinking adding on more RAM but am not sure the investment will be worth it, if Xcode just doest want to work.

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.
