Why not ask your question on the new OpenStreetMap Community Forum?

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()?
