introduce usage of github for adding pacages in xcode project

GitHub is a widely used platform for version control and collaboration in software development. While it is not directly used for adding packages in Xcode projects, it can be leveraged to manage dependencies and integrate third-party libraries into your Xcode project.

Here’s a general overview of how you can use GitHub to add packages to your Xcode project:

1. Identify the package or library you want to add to your Xcode project. Many popular iOS packages and libraries are hosted on GitHub.

2. Visit the GitHub repository for the package and locate the installation instructions or documentation. Most repositories will provide guidelines on how to integrate their package into your project.

3. Typically, packages can be added to your Xcode project using package managers like CocoaPods or Swift Package Manager (SPM). These tools simplify the process of managing dependencies in your project.

– CocoaPods: If the package supports CocoaPods, you’ll need to install CocoaPods on your machine first. Then, create a Podfile in your Xcode project’s root directory and specify the package as a dependency. Finally, run `pod install` in your terminal to install the package and generate an Xcode workspace. Open the workspace in Xcode to start using the package.

– Swift Package Manager (SPM): If the package supports SPM, you can add it directly from Xcode. Open your Xcode project, go to File -> Swift Packages -> Add Package Dependency. Enter the package’s GitHub URL or search for it, and Xcode will fetch and integrate the package into your project.

4. Once the package is added, you can import and start using it in your Xcode project. Refer to the package’s documentation or examples for usage instructions.

Remember to regularly update your packages to benefit from bug fixes and new features. You can use the package manager commands (`pod update` for CocoaPods or `swift package update` for SPM) to update your dependencies.

Using GitHub and package managers allows you to easily add and manage external packages in your Xcode project, making it more efficient and enabling you to leverage a wide range of community-developed libraries and frameworks.
