Usage

To use the Zoomable modifier in your SwiftUI view:

        Image("your-image-name")
            .zoomable()
    }
}

Requirements

  • iOS 16.0 or later
  • SwiftUI

Caveats

  • iOS 16: Due to limitations with MagnificationGesture, during pinch-in actions, the zoom location is fixed to the top-left corner.
  • iOS 17 and later: This issue has been addressed and improved with the introduction of MagnifyGesture.
