iOS Integration

import SwiftUI
import FlagsGG

@main
struct MyApp: App {
    let flags: Flags

    init() {
        flags = try! Flags.builder()
            .withAuth(Auth(
                projectId: "your-project-id",
                agentId: "your-agent-id",
                environmentId: "your-environment-id"
            ))
            .build()
    }

    var body: some Scene {
        WindowGroup {
            ContentView(flags: flags)
        }
    }
}

struct ContentView: View {
    let flags: Flags
    @State private var showBeta = false

    var body: some View {
        VStack {
            if showBeta {
                Text("Beta feature!")
            }
        }
        .task {
            showBeta = await flags.is("beta-ui").enabled()
        }
    }
}

macOS / Server-Side Swift

For server-side Swift (e.g., Vapor), initialize the client once and share it across request handlers:

import Vapor
import FlagsGG

func configure(_ app: Application) throws {
    let flags = try Flags.builder()
        .withAuth(Auth(
            projectId: "your-project-id",
            agentId: "your-agent-id",
            environmentId: "your-environment-id"
        ))
        .build()

    app.storage[FlagsKey.self] = flags
}

Rust API Compatibility

The Swift SDK maintains API compatibility with the Rust SDK:

Rust	Swift
client.is("name").enabled().await	await client.is("name").enabled()
client.list().await?	try await client.list()
client.get_multiple(&[...]).await	await client.getMultiple([...])
client.all_enabled(&[...]).await	await client.allEnabled([...])
client.any_enabled(&[...]).await	await client.anyEnabled([...])
