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 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 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
• 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
• 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
• 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 using macOS Server to automatically build and test your apps
• Monitor performance and user interface test data using macOS Server to immediately spot regressions
• Analyzer travels countless code paths looking for logical errors before they become bugs

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 macOS Server. Some features may require Internet access.

Error readings are faulty?

Been getting error readings that are duplicated and faulty. In my project, I have been receiving an error where it states “View controller is unreachable because it has no entry points..” Of course I can fix it by creating a segue between my two views or by creating a storyboard ID. The problem arises when it provides not only one warning but two of the same identical warnings, in which I was able to knock one of them off by creating a storyboard ID (the other warning will be fixed through a segue). Its very confusing since I am creating a duplicate app (app is essentially similar to how Uber has a driver and rider app respectively, so pretend this duplicate is the rider version) in which the duplicate seems to only have one of the same warnings instead of two (which will be fixed for sure when I complete the segue). This leads to my second issue.

When I create my second attempt at the driver version (after deleting the first attempt because I was thinking it was a glitch, thus decided to create a new project file to recreate it in hopes the warnings won’t be there) under the same name for the project, it seems to pop up those TWO SAME warnings BEFORE I do anything to the storyboard and controller…. very very weird. But if I made the driver version under a diff name (instead of “Uber for driver” I write “Uber driver” for example), it would start from a clean slate with no errors as its supposed to. Hope this gets fixed soon as its very confusing to code.

Just what I need

A great program for kids (like me) who want to get into programming. I have now 2 apps in the app store only using Xcode. Crashes some times but still saves what I was working on. Great program! Only thing to improve would be to show where the app crashes in the code and not just in the debugger.

will not install

I want the update but it will not install tried several times, get with it APPLE!
