Description

VideoCacheManager is a lightweight Swift utility for caching videos locally in an iOS application. It helps efficiently store and retrieve downloaded video files, reducing redundant network requests and improving performance.

🚀 Features

• ✅ Singleton instance for easy access
• ✅ Stores cached videos in the app's cache directory
• ✅ Retrieves cached videos using a unique key
• ✅ Downloads and caches videos asynchronously
• ✅ Handles errors gracefully

📌 Usage

🔍 Retrieve Cached Video

if let cachedURL = VideoCacheManager.shared.getCachedVideoURL(for: "videoKey") {
    // Use the cached video
}

let videoURL = URL(string: "https://example.com/video.mp4")!
VideoCacheManager.shared.cacheVideo(from: videoURL, key: "videoKey") { cachedURL in
    if let cachedURL = cachedURL {
        print("Video cached at:", cachedURL)
    } else {
        print("Failed to cache video")
    }
}

⚙️ How It Works

• Uses FileManager to create a VideoCache directory inside the app’s cache folder.
• Checks if a video is already cached before downloading.
• Downloads the video asynchronously using URLSession.downloadTask.
• Moves the downloaded file to the cache directory for persistent storage.
