When zooming, show previous over zoomed tile until tiles load

I've been thinking of the exact same thing!

I gave it a shot, and I'm creating low res files and returning them if the image isn't immediately available and calling result(tempTileData, nil), but when the full res tile is ready, calling result with the full res image seems to be ignored.

Hi @3DTOPO

Some time ago I thought about how this could be implemented, precisely to overcome the challenge that you're facing. At that time I did not know how to replace the temporary tile with the actual one, what I understood is that once you tell the tile layer this is the file it keeps it... so what I thought could be a possibility was to add a new tile layer underneath of the regular one that would hold the temporary zoomed tiles.

In addition there is one parameter that sets transparency of the regular tiles one that is set to non-transparent to prevent Apple Maps to be displayed. You have to change it to be able to see the zoomed tiles.
