This is the repo for shared Rust code to be used in Swisstronik Swift & Kotlin.

Usage:

Swift using swift build

Add it to your dependencies in Package.swift:

dependencies: [
    .package(url: "https://github.com/SigmaGmbH/swisstronik-rust-swift-kotlin", from: "1.0.0"),
],

Then add the library to target's dependencies:

.product(name: "SwisstronikSwift", package: "SwisstronikSwift"),

or, add it using XCode:

Swift using Xcode

If you are using Xcode, then you should:

• Add this SwiftPM package https://github.com/SigmaGmbH/swisstronik-rust-swift-kotlin as dependency of your xcode project: Apple Docs

Kotlin

The package is hosted on Github Packages. In order to use it, you need to authenticate on Github using your token.

        url = uri("https://maven.pkg.github.com/SigmaGmbH/swisstronik-rust-swift-kotlin")
        credentials {
            username = project.findProperty("gpr.user") ?: System.getenv("USERNAME")
            password = project.findProperty("gpr.key") ?: System.getenv("TOKEN")
        }
   }
