Hi I'm Newbie I'm trying to make openstreetmap's tile on my iOS app(swift). but when I try to do , like "http://tile.openstreetmap.org/7/63/42.png" first one is zoom, second tileX, third tileY. and I want to convert my latitude and longitude to tileX, tileY. Surely I find https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames#X_and_Y this page trying to convert but i'm newbie in iOS(swift) so I can't do that. So conclude, I want to know how to my latitude and longitude to tileX, tileY in "http://tile.openstreetmap.org/7/tileX/tileY.png" if this method is wrong then what can i do for it? thank you for reading my question. |

"...but i'm newbie in iOS(swift) so I can't do that." Why not? The article you linked to provides step-by-step calculations you can use to convert from latitude and longitude to the corresponding X and Y. I'm not familiar with Swift. Is it not capable of performing trigonometric operations like tan()?
