RemoteImage

by Jack Palevich

Yet another remote image package for SwiftUI.

This one's better than most other RemoteImage implementations because:

• It takes an optional maximum size parameter, and scales down large images to fit the given maximum size.
  • by default images will be clamped to be no larger than full screen size.
• It pre-rasterizes the image off the main thread, which greatly reduces "jank" when the image is first show.

Example

import RemoteImage
import SwiftUI

struct ContentView: View {
  
    var body: some View {
      GeometryReader{proxy in
        RemoteImage(loader:ImageLoader(
          url:URL(string:"https://example.com/myimage.jpg")!,
          targetSize: proxy.size))
    }
  }
}

Thanks to all the RemoteImage tutorials on the web, especially:

• Hacking With Swift
• Christian Elies
• MovieSwiftUI
• SwiftUI-lab for GeometryReader insights.
• Apple Example code for limiting the decoded size and pre-rasterization.

And probably other tutorials that I've accidentally omitted.
