Description

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 Cocoa frameworks and 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 place to experiment with Swift code, displaying instant results
• Interface Builder is a graphical UI design canvas with a live preview of your app
• 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
• Preview your interface in different screen sizes, orientations, or languages
• 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

Apple LLVM technology finds and fixes bugs for you
• Analyzer travels countless code paths looking for logical errors before they become bugs
• Live Issues identifies coding mistakes as you type with no need to build first
• Fix-it can confidently correct mistakes for you with just a keystroke

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 OS X Server to automatically build and test your apps
• Monitor performance and user interface test data using OS X Server to immediately spot regressions

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 OS X Server. Some features may require Internet access.

What's New in Version 7.3.1

Xcode 7.3.1 includes Swift 2.2 and SDKs for iOS 9.3, watchOS 2.2, tvOS 9.2, and OS X 10.11 El Capitan.

Instability is becoming unmanageable

I’ve tried so hard not to write this review. An IDE is a huge complicated piece of software, and a trade off must be made of spending time on stability vs new features to improve developer productivity. However Xcode has got to the point where it is costing me huge amounts of time each day. Each release becomes less stable and I am now at the point where our project is sufficiently complex enough that I have to use 2 IDE’s Xcode for simply running/debugging and AppCode for writing the software.

I am dreading having to upgrade to Xcode 8 for iOS 10 and long for the olden days of Xcode 3 with seperate interface builder, sure it was under featured but it did not cost me any where near as much time as the later versions have. Please please please Apple give us stable developer tools to work with, or better yet assign some guys over to JetBrains and let AppCode become the official Apple IDE. We didm’t need another language we needed another IDE!

Why can’t apple sort out the updating problems?

Xcode works great, but then you’ll need to update it, you’ll dread it, but devices will update and you will need a current version of Xcode to develop for them, so you’ll be forced to update, and what will happen, well in my experience 1 in 3 times you’ll spend a couple of hours trying to make it work, it’ll sit there at 0% or paused, i clicked update to 7.1 about a month ago, i left it there in the lauchpad thing wondering if it would ever start, month later and 9.2 ios came out i had to get Xcode 7.1 and had it started? Nope, i had to completely clean Xcode from my system and restart before i could get the update. SORT IT OUT. why not just provide a disk image with it on the developer site if you cant get it to work with app store?

A further update to my review, ive had to update again, guess what it doesnt work. Apple dont care though do they, its a complete pile of……..

Waiting an hour for it to re-install

Since 7.3 came out, in my experience, it’s been NOTHING but trouble. Changes in Swift are understandable for the sake of progress, but the bugs and glitches introduced make no sense. I’ve lost audio in Playgrounds and all simulators which has led me to try a reinstall. Aside from taking the best part of an hour to fully (I hope) uninstall, I’ve been waiting for over 45 minutes for the re-install and have no idea if it’s even progressing…

I’m not usually a complainer, but this richly deserves yet another a grumpy bad review while I stare at the ‘Installing’ icon!
Yet another completely lost day’s work with 7.3.1.

One star but ‘Nul Points’. Bring on the next update!!
