Every now and then I dust off Xcode to try and build myself some (pretty simple) native macOS app – just for funsies.

For reference I am a backend dev at a SaaS company dealing primarily in Python & Go, doing HTTP/gRPC services and talking to databases.

Last night I attempted to make a program that would display an image and allow the user to click the image and then display the hex value of the colour under the cursor.

I wanted my application to use a crosshair cursor and after an hour of looking at the docs for NSCursor[1] and stackoverflow I just gave up.

I don't know how someone gets started in this ecosystem but I am sure once you know it this stuff is easy.
