Peregrine

Peregrine for iOS is written in 100% Swift. Use Codable interfaces for type-safe serialization and de­serialization.

struct LocationResponse: Encodable {
    let lat: Double
    let lng: Double
}

func getLocation(call: Call) {
    ⋯
    let response = LocationResponse(
        lat: location.coordinate.latitude,
        lng: location.coordinate.longitude
    )

    try! call.respond(with: response)
}

const { lat, lng } = await client.getLocation()

console.log(`You are at Latitude: ${lat}, Longitude: ${lng}`)

Use Apple’s Combine framework to build reactive data pipelines that send asynchronous events to the web layer.

struct KeyboardEvent: Codable {
    let state: String
    let height: Double
}

class Keyboard {
    @Published var keyboard: Event?
    ⋯
    init() {
        ⋯
        Publishers
            .MergeMany(willHidePublisher, didHidePublisher, willShowPublisher, didShowPublisher)
            .assign(to: &$keyboard)
    }
}

const { Keyboard } = client

for await (const { state, height } of Keyboard.keyboard$) {
  console.log(`Keyboard is ${state}, height: ${height}`)
}
