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 11.2.1 includes Swift 5.1 and SDKs for iOS 13.2, iPadOS 13.2, tvOS 13.2, watchOS 6.1, and macOS Catalina 10.15.1
This update fixes a critical issue that could cause apps using UITextView to crash
Ratings and Reviews
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.
Great - Despite the haters
I've been writing software and using IDEs for over 20 years and XCode is probably better, overall, than anything else available on any platform. And that list includes every major IDE you've ever heard of. Yes it has some issues here and there. But none of those are show stoppers, and in my career I've never seen a commercial application of any kind that didn't have room for improvement.
Out of 2,096 ratings for XCode (as of this one), to see an equal number of 1-star ratings (versus 5-star) and not much in between, tells me there are a lot of trolls out there who don't use this tool to earn their living (like I do), yet they think their comments matter for some reason.
If you want an honest review, talk to someone who is a professional developer, and who uses this specific tool 8-hours a day to earn their living. If their full time job title does not include the words iOS Developer, then I would pretty much discount whatever they say.
I don't work for Apple, or even know anyone who does, but in my opinion, Apple should not let someone post a review this app unless at a minimum that person has a current paid Apple developer subscription. At least then you'd know that the trolls had to pay $99/year in order to post their 1-star reviews, which in turn would eliminate the majority of them.
THE BEST BY FAR
Easy to use. Able to be factory restored by internet. Able to debug iPhone INTERACTIVELY. FULL HARDWARE SUPPORT for the best multimedia - not software emulation freeware - real industry codec.
Runs true BSD Unix great "tools", GPL too. Very stable kernel. The best quality hardware. Visually outstanding and handicap features too. Absolutely the best.
One caveat is the weakness in the "game release" - directx has never gotten supported (for game porters to make use of) - however Unity game engine DOES support Apple OS.
But really - cross platform is bull (anything worth it needs non-free drivers); most apps today would be better done with XCode than to attempt cpt's. Something like Unity uses XCode that so game writers don't have to do it - they somehow have the time and money to make tools Apple has not had ? :) Just a gaming company?
Truly apple is often 1 yr behind on "hardware version" release - but they are so much better releases they run better than a pc with "later" hardware.
XCODE allows developers to release apps that span support for users seemlessly on app store. Once released (if a user doesn't upgrade their device), their device never stops being able to run the app software. The developer can release for many apple platforms at once. They are not "guessing game" support each apple device is directly supported. Support is not a guessing game with apple.
With Family Sharing set up, up to six family members can use this app.
