hello i have created an osx app containing one image well and one grid. i the plan is that i can drag an image filename from finder and drop them in the image well or grid. if i drop it in the image well, the image file will be displayed in the well. if i drip it in the table the filename will appear there. how do i do this in c# synced with swift? i have looked up for some but not found an example that works in this environment. thank you
