libcmark_gfm
Swift compatible framework for cmark-gfm. Works with CocoaPods, Carthage, and the Swift Package Manager.
You can use libcmark_gfm directly, or consider using Maaku.
Maaku provides a Swift wrapper around libcmark_gfm with the addition of a Swift friendly representation of the AST. gfm extensions for tables, strikethrough, autolinks, and tag filters are supported.
TexturedMaaku builds on top of Maaku together with Texture to provide a native iOS CommonMark rendering framework in Swift.
