Yeah, it was obvious that writeRowsWith: would soon be deprecated. After going
through the documentation a bit, I did it via:
func tableView(_ tableView: NSTableView, draggingSession session:
NSDraggingSession, willBeginAt screenPoint: NSPoint, forRowIndexes rowIndexes:
IndexSet) {
session.enumerateDraggingItems(options: .concurrent,
for:
nil,
classes: [NSPasteboardItem.self],
searchOptions: [:],
using: { (draggingItem, index, stop) in
// Generate Image
let canvas = NSImage.init(size: canvasSize)
draggingItem.setDraggingFrame(NSMakeRect(session.draggingLocation.x,
session.draggingLocation.y, canvas.size.width, canvas.size.height), contents:
canvas)
})
}
