This is now listed here, but I wanted to give it a signal boost. As part of a larger project, I’m adding support for authenticating a Solid Pod user in a native iOS app: SolidAuthSwift. As the name implies, this is written in Swift. It is provided as a Swift package. It heavily is based on @wrmack’s earlier work with Get-tokens. I don’t yet have it in a production app, but plan to so in the next weeks/months.
Happy to have questions on it, and PR’s.
