Camera View – SwiftUI – Combine

Creating Camera View based on Combine & SwiftUI

Presenting the camera view and accessing each frame have never been so much easier rather than this.


How it works

SwiftUI is a declarative program, which means that it creates its views each time something changes in the data that it should be presented.

So with the help of AvFoundation and accessing the camera as an input device for AVSession, we can have each frame as a CVImageBuffer as an output.

So then with the help of Combine we can publish each frame and present it. The huge benefit of that you can manipulate and add filters or even change one frame :).

Best Use cases:

  • Creating a filter app
  • Computer vision
  • Image processing
