Overview
This lecture covers the steps to download, install, and set up Xcode for iOS app development, including creating your first project.
Downloading and Installing Xcode
- Visit developer.apple.com/xcode/ to access the official Xcode webpage.
- You need an Apple Developer account to download Xcode from the website.
- Alternatively, Xcode can be downloaded from the Mac App Store using an Apple ID.
- The downloads page offers various tools, but only Xcode is relevant here.
- Choose the latest stable version of Xcode (recommended), not the Beta version.
- Download the Xcode.xip file and extract it after completion.
- Move the extracted Xcode app to your Applications folder.
- Open Xcode from the Applications folder and follow any installation prompts.
Creating a New Xcode Project
- Open Xcode and choose "Create a new Xcode project" on the welcome page.
- Select the "App" template for iOS development and click Next.
- Enter a product name (e.g., hello_world) and set team options to add collaborators if needed.
- Fill in organization and bundle identifiers to uniquely identify your app.
- Choose the interface method: select Storyboard for this tutorial.
- Choose Swift as the programming language for your project.
- Uncheck the "Source Control" option as it's not required at the beginner stage.
- Choose a location to save your project and click Create.
Exploring the Xcode Environment
- The project pane on the left gives access to all project files.
- The top bar has a play button to run the app in a simulator.
- The simulator allows you to test your app without a physical device.
- More detailed simulator usage will be covered in later lessons.
