SpriteKit supports tile maps as of iOS 10 and has a pretty powerful engine. Only, I am having trouble discovering if it is possible, and how to natively create, tile sets directly from a tileset image.
For example, it seems that many other tile map programs (such as Tiled) support uploading a single tileset image with a few inputs (16x16 tiles at 64px for each tile, for example) to create an array of tile textures. The only way that I've found to integrate this with Xcode's new SKTileSet feature is to manually crop each tile into it's own image, upload that image into a separate texture, and access them via name.
Is there a better way to upload a tile map image and access its tiles using Apple's SKTileMapNode engine?
