Overview
This lecture covers how to add a video file to an Xcode project and use Bundle.main.path in Swift to access the file within your app.
Adding a Video File to Xcode Project
- Drag and drop the video file (e.g., test.mp4) into the Video Player Project folder in Xcode.
- When prompted, select the existing project folder (e.g., Video_Player) as the target.
- Click "Finish" to add the file to the project directory.
Ensuring File is Bundled with App
- Select the main Xcode project/root folder (video_player).
- In the Targets pane, choose the video player target and expand the Copy Bundle Resources tab.
- Confirm that test.mp4 appears in the resources list; add it manually if missing.
Accessing Video File in Swift Code
- Open the ViewController file to add logic for accessing the video.
- Define a new private Swift function such as
private func findVideo() { ... }.
- Use
guard let with Bundle.main.path to safely find the video's path and handle errors if not found.
- Update the resource name in the code to match the added file (e.g., "test" for test.mp4).
Common Coding Practices & Troubleshooting
- Use the
guard statement to handle optional path values safely and prevent runtime errors.
- A warning appears if the path variable is declared but not used yet; this is normal during stepwise development.
Key Terms & Definitions
- Bundle.main.path — Function used to locate a file by name and type within the app's main bundle.
- Copy Bundle Resources — Xcode setting that determines which files are included with the app during build.
- guard — Swift keyword to check conditions and exit early if they're not met.
Action Items / Next Steps
- Practice adding a video file to an Xcode project and confirming it’s in Copy Bundle Resources.
- Write Swift code using
Bundle.main.path to access the new video file.
- Prepare for upcoming lessons on building the full video player application.
