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 easy and fun.
Xcode includes the Xcode IDE, Swift and C/C++/Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features:
Innovative tools help you create great apps
• Swift is an intuitive programming language that is safe, fast, and modern
• SwiftUI is a revolutionary framework to create user interfaces with a declarative Swift syntax
• Playgrounds are a fun way to experiment and interact with Swift code
• View debugging shows a 3D stack of all your app's UI view layers at runtime
• Split editors in virtually unlimited ways, show previews, or choose an assistant to see related content
• Live issues display errors as you type, and Fix-its improve your code with just a click
• Source control navigator and service integrations help you manage code across a team
SwiftUI and Interface Builder make it easy to design your interface
• SwiftUI uses declarative Swift code that clearly describes your interface
• Design canvas graphically builds UI views using the library of controls and modifyers
• Preview SwiftUI code or UIKit interfaces in different screen sizes, orientations, and font sizes
• SwiftUI code is always in perfect sync with the graphical design canvas and previews
• Animations are built using simple commands that describe the action you want to see
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
• Open Quickly instantly opens any file within your project
• Data tips and Quick Look can inspect a variable by hovering your mouse over code while debugging
Instruments for performance analysis
• 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 run applications on an iPhone, iPad, Apple TV, or 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.

Ratings and Reviews
Great product, but suggestions...
I've been using Xcode for the past several years, I want to leave a comment that this is a great product. Although I am not sayting that the IDE itself and the graphical whatever editing tricks are great. I focus more on the frameworks, libraries, supprt, tools and the integrated package that tranforms a mac to a development machine, and Apple has consistently been great at supporting the development on OS X (macOS). The suggestion might be to provide an integrated end-to-end pakcage that becomes the ultimate development environment so I won't have to install 3rd party packaging systems, library systems, extra-IDEs for different languages, and dozens of emulation, environment, and differnet packages and dependencies for differnet tasks. Putting everything in Xocde seems a bad idea to increase the size (and responsiveness) of the software but it is much better than the overhead of doing fancy stuff and launching dozens of programs just to start working (which takes up lots of concurrency resources which a dual-core laptop I am using might not be the best choice).
Not perfect, but close enough
There are a few things I don't like about Xcode, but as a whole, it is the best totally free option for iOS development. Better yet, it is totally native. I am an amateur developer, and I have really enjoyed working on Xcode. I recommend giving it a try. The documentation is great and there are a lot of really helpful support videos from non-Apple supported persons, just trying to lend a hand.
I started, knowing nothing about Xcode or Swift, and punched out my first iOS app in less than a month. I was extremely nervous, having all my programmer friends telling me that apple was really strict when reviewing applications. I took the precautions of reading through the Apple documentation before hand, shockingly, my first application went through without a hitch and was on the App Store within 48 hours of submission.
I will admit to using an online class to learn the basics, it was very helpful in getting me familiar with the Xcode environment. I can't provide specifics since I don't know how Apple will feel about promoting someone else's work on a review.
Developer tool in simulator stop working after a few minutes
After launching an app in a simulator, cmd D and cmd R stop working after a few minutes of the app running. This happens with all 3 apps I have on my machine and am trying to work on. The only way to fix it is to stop the application and hit play again. This costs a lot of time when I'm trying to inspect components in the app and I constantly need to stop and rebuild my app into the simulator.
Another year and yet another broken version of xcode. Seriously this kind of thing happens every single year, please take the time and the care to actually test this out in the months leading up to the release. Stop using us developers as your beta testers, we rely on this tool working properly at all times as it is literally the only tool we can use since apple doesn't allow anything else.
This is incredibly frustrating and causes a lot of downtime every single year when these new version of xcode get released without being tested. If you're making us pay yearly to use this tool, then it needs to work 100% of the time and can't have simple bugs that break the development process.
