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.
Xcode 10.3 includes SDKs for iOS 12.4, tvOS 12.4, watchOS 5.3, and macOS Mojave 10.14.6
Ratings and Reviews
Flawed but still fantastic IDE software
I have been using Xcode for the last 7 years as an senior iOS engineer. What can I say, it’s came along nicely as the defacto iOS development in development environment. Weather your a beginner or season developer this is the must tool for many job when working on iOS products. Not going to lie that this software does have flaws, as with all things there will always be some degree of issues. The fact it offers WYSIWYG interface builder saves masses of hours in development time. With extensions such as playground, it can never be said that the software does not push for coding innovations.
High Five Apple
OK I have just started working with Xcode and C++ after working with an alternative very expensive product at work, and I think that Xcode knocks the spots off of the competition. It's really fantastic and I am very pleased that this quality product is produced and supported by Apple. The support site is also a gerat place to find additional rescources and obviously developer support. I have looked down below and feel like I'm a little out of line, its difficult to think of an improvement. Yes, my Macbook Pro has been running a little hotter while: coding, debugging, and assembling, so I am looking into how to mittigate this feature. But the softare it’s self is wonderful and has a silky smooth interface and feel, big high five to the Xcode development team. And please keep the C++ support, for me this is the best bit.
Updating is a nightmare!
Dowloading and updating in Mojave is a nightmare. If your internet connection is interrupted even for a few seconds, download stops, does not resume. Have to reboot. Start download again, but first it decides it needs to read all 6GB of the existing installation of Xcode from the hard disk before it decides it needs to start downloading the new 6GB file (from the beginning again). It has now taken over a full working day to update the OS and attempt to update Xcode, which is still not installed yet, because sometimes it just stops downloading for no reason after a couple of GB. How much do you think it costs to have a development machine out of action for 24 hours? Multiply this by every dev experiencing a similar issue.
