Just a quick announcement that I've released a new Tiled parser for Swift/SpriteKit. This began life as an XML parser for a game I worked on, and I've been steadily updating it whenever I've had down cycles. I've decided to clean it up and open-source the project:
The repository has branches for Swift 2.3 & 3 and the included demo project compiles in Xcode 8 with a sample scenes to mess around with. It includes both iOS & macOS versions, reads embedded & external tilesets and all map types (orthogonal, isometric, hexagonal and staggered).
Please feel free to contact me here or on github with questions/comments.
