Simple example of using onDrop(of:delegate:)

DropAcceptingView.swift

import SwiftUI

struct DropAcceptingView: View {
    @State private var selectedImage: Image?

    var body: some View {
        ZStack {
            Rectangle()
                .fill(.secondary)

            Text("You can drop an image here")

            selectedImage?
                .resizable()
                .scaledToFit()
        }
        .aspectRatio(1, contentMode: .fit)
        .onDrop(of: [.image], delegate: self)
    }
}

extension DropAcceptingView: DropDelegate {
    func performDrop(info: DropInfo) -> Bool {
        guard info.hasItemsConforming(to: [.image]) else { return false }

        var result = false

        if let itemProvider = info.itemProviders(for: [.image]).first {
            if itemProvider.canLoadObject(ofClass: UIImage.self) {
                result = true

                _ = itemProvider.loadObject(ofClass: UIImage.self) { reading, error in
                    if let error = error {
                        print("Error: Image drop failed - \(error)")
                    } else {
                        if let image = reading as? UIImage {
                            selectedImage = Image(uiImage: image)
                        }
                    }
                }
            }
        }

        return result
    }
}
