iOS SDK

ResolveKit iOS SDK embeds agent chat and native tool execution inside iOS/macOS apps.

Requirements

• Swift tools: 5.9+
• Xcode: 15+
• Platforms: iOS 16+, macOS 12+
• Backend: running ResolveKit agent runtime with valid API key

Installation (SPM)

In Xcode: File → Add Package Dependencies with:

https://github.com/resolve-kit/resolvekit-ios-sdk

Or in Package.swift:

dependencies: [
    .package(url: "https://github.com/resolve-kit/resolvekit-ios-sdk", from: "1.4.2")
],
targets: [
    .target(
        name: "YourApp",
        dependencies: [
            .product(name: "ResolveKitUI", package: "resolvekit-ios-sdk")
        ]
    )
]

Module Layout

• ResolveKitCore: JSON/value types, function protocol, registry, schemas
• ResolveKitAuthoring: @ResolveKit macro and authoring protocol
• ResolveKitNetworking: REST + SSE clients
• ResolveKitUI: runtime + SwiftUI chat view + UIKit/AppKit controllers

Minimum Integration

1. Define a function

import ResolveKitAuthoring

@ResolveKit(name: "get_local_time", description: "Returns current local time", requiresApproval: false)
struct GetLocalTime: ResolveKitFunction {
    func perform() async throws -> String {
        let formatter = ISO8601DateFormatter()
        formatter.timeZone = .current
        return formatter.string(from: Date())
    }
}

2. Create runtime

import ResolveKitUI

let runtime = ResolveKitRuntime(configuration: ResolveKitConfiguration(
    baseURL: URL(string: "http://localhost:8000")!,
    apiKeyProvider: { "iaa_your_api_key" },
    functions: [GetLocalTime.self]
))

3. Show chat UI (SwiftUI)

import SwiftUI
import ResolveKitUI

struct ContentView: View {
    @StateObject private var runtime = ResolveKitRuntime(configuration: ResolveKitConfiguration(
        baseURL: URL(string: "http://localhost:8000")!,
        apiKeyProvider: { "iaa_your_api_key" },
        functions: [GetLocalTime.self]
    ))

    var body: some View {
        ResolveKitChatView(runtime: runtime)
    }
}
