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.

새로운 기능

9.4업데이트했다가4시간버린사람 ,

9.4로 업데이트 하시는 분들 하시다가 2분 대에서 멈추시거나 하시면 그냥 앱을 삭제했다가 다시 설치하세요..

업데이트 했다가 4시간 동안 아무것도 못했습니다... 설치 중간에 2분대가 되면 그 상태에서 2시간 넘게 기다려도 아무것도 안되네요. 무슨 오류가 발생했다고 안내가 있는 것도 아니구요.
재시작하고 별 짓을 다했는 데도 안 되서 결국 엑코를 삭제했다가 재설치하니까 그제서야 되네요.

평소에도 조금만 디버깅하면 튕기고 스토리보드 켜면 죽고 시뮬레이터 연결하다 죽고 계속 그러네요.
업데이트까지 이러시면 곤란합니다...

다운로드 속도

처음에 느리다가 점차 빨라지긴 하는데 그래도 조금만 더 빨리 다운로드 받을 수 있도록 해주시면
감사하겠습니다. 그리고, Mac OS 에서 사용하기에 이만한 개발툴 없는 것 같습니다. 윈도우 사용하다
맥에 입문해서 어떤 개발툴 써야 하지? 이런 고민 하시는 분은 그냥 Xcode 쓰세요.

downdate xcode

navigation controller 검색되는 것이 안에 들어와 있을 때가 더 편했습니다. 분리되니까 산만해집니다.
그리고 업데이트 하다가 설치 안되서 지우고 다시 깔았는데 git 연결 한거 다 날라가고 연결 해도 기존처럼 연결도 안되고 업데이트 하라고 해서 지금 업데이트 중인데 지난번처럼 완료도 안되고 내부에 마이크로소프트 첩자 있나요? 마피아라도 있는건지 업데이트가 아니라 downdate되고 있습니다. 호환성이 점점 안좋아지고 있어요. 발전하는게 아니라 끝을 모를 정도로 접근성 떨어지는 인터페이스에 할말을 잃습니다.
