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 new 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
• 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 build and test on a server Mac running Xcode
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.
Xcode 12.1 includes Swift 5.3 and SDKs for iOS 14.1, iPadOS 14.1, tvOS 14, watchOS 7, and macOS Catalina
• App Clips are a small part of your app that’s discoverable at the moment it’s needed, loads in seconds, and launches quickly
• WidgetKit uses SwiftUI to build beautiful new widgets that users can install directly on their iPhone home screen
• StoreKit testing framework and transaction manager make it easy to test and debug in-app purchases
Refined user interface
• Document tabs open any type of document in a lightweight editor tab, including logs, asset catalogs, and UI files
• Navigator fonts are now resizable based on the system setting, or can be manually configured
• Code completion has a new, simplified interface that is faster, and makes it easier to choose the correct code
• Organizer is completely redesigned, and reports new app metrics such as hitches in animation and scrolling
Swift and SwiftUI
• Performance for SwiftUI has been improved throughout, and new Lazy views can efficiently handle enormous data sets
• SwiftUI Views can be turned into reusable components that appear in the Xcode library and in code completions
• Swift Package Manager supports resources and localizations, making it great for sharing SwiftUI components
• Swift compiler’s improved diagnostics make it much easier to understand coding mistakes, especially in SwiftUI code

Shouldn’t be out of beta
Xcode in itself doesn’t change much year to year so on that end, everything is fine. However, this version of Xcode has completely ruined user interaction. I don’t actually believe that Apple even tested Xcode out using their trackpads because everything regarding storyboards is completely broken. When it comes to scripts, I have no issues. Everything just works. But when it comes to storyboards, I can resize an element or drag it to another spot without weird glitches such as the element flying off the screen and getting deleted. When I drop a textfield element and insert a default value, the text y position is so far down you can only see the top of the letter even though the font size is default and the alignment is perfectly centered horizontall and vertically. Changing between storyboard tabs such as going to the attributes inspector causes the object you are focused on to deselect. How did that even happen?
The worst part about this update is that Xcode 9 Beta 4 was a better build than this release and that was 6 weeks ago. I would say that I don’t recommend updating to this new version as it’s usability seems to be even less than beta to me, but unfortunately, Apple kind of puts you between a rock and a hard place. You basically have to update to this version to keep apps up to date and release those brand new apps to iOS 11 devices.
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.
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.
With Family Sharing set up, up to six family members can use this app.
