[ Swift for Mac OS ] Load video meta data from URL – duration, natural size and creation date (and more) in Swift. This looks expensive so make sure you store results somewhere for re-use. Bonus: get image pixel dimensions from (local image file) URL!

ImagePixelDimensions.swift

// For images...

import AppKit

extension URL {   

  func getImageSize() -> CGSize? {
        guard let src = CGImageSourceCreateWithURL(self as CFURL, nil) else {
            return nil
        }
        
        guard let props = CGImageSourceCopyPropertiesAtIndex(src, 0, nil),
                let properties = props as? [String: AnyObject]  else {
            return nil
        }
        
        guard let w = properties["PixelWidth"], let h = properties["PixelHeight"] else {
            return nil
        }
        
        let size = CGSize(
            width: w.intValue as Int,
            height: h.intValue as Int)
        
        return size
    }
}

VideoMetaData.swift

// For video...

import AVKit

struct VideoInfo {
    let isPlayable: Bool
    let duration: Double
    let creationDate: Date?
    let size: CGSize?
}

extension URL {
  func getVideoInfo() async -> VideoInfo? {
        let asset = AVURLAsset(url: self)
        do {
            let (isPlayable, duration, tracks, creationDate) = try await asset.load(.isPlayable, .duration, .tracks, .creationDate)
            let (naturalSize) = try await tracks.first?.load(.naturalSize)
            let (date) = try await creationDate?.load(.dateValue)
            
            return VideoInfo(
                isPlayable: isPlayable,
                duration: duration.seconds,
                creationDate: date,
                size: naturalSize
            )
        } catch {
            return nil
        }
  }
}
