How to use callkit-voip on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add callkit-voip

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/dpearson2699/swift-ios-skills --skill callkit-voip

Fetches callkit-voip from dpearson2699/swift-ios-skills and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ────────────────

│ · Cline · Codex · Goose · Windsurf

│ ●Cursor(selected)

│ · Cursor · Aider · Continue

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/callkit-voip

Restart Cursor to activate callkit-voip. Access via /callkit-voip in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

✓

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

✓

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

Setup

Project Configuration

Enable the Voice over IP background mode in Signing & Capabilities

Add the Push Notifications capability

For call directory extensions, add a Call Directory Extension target

Key Types

Type

Role

CXProvider

Reports calls to the system, receives call actions

CXCallController

Requests call actions (start, end, hold, mute)

CXCallUpdate

Describes call metadata (caller name, video, handle)

CXProviderDelegate

Handles system call actions and audio session events

PKPushRegistry

Registers for and receives VoIP push notifications

Provider Configuration

Create a single CXProvider at app launch and keep it alive for the app lifetime. Configure it with a CXProviderConfiguration that describes your calling capabilities.

import CallKit /// CXProvider dispatches all delegate calls to the queue passed to `setDelegate(_:queue:)`. /// The `let` properties are initialized once and never mutated, making this type /// safe to share across concurrency domains despite @unchecked Sendable. final class CallManager: NSObject, @unchecked Sendable { static let shared = CallManager() let provider: CXProvider let callController = CXCallController() private override init() { let config = CXProviderConfiguration() config.localizedName = "My VoIP App" config.supportsVideo = true config.maximumCallsPerCallGroup = 1 config.maximumCallGroups = 2 config.supportedHandleTypes = [.phoneNumber, .emailAddress] config.includesCallsInRecents = true provider = CXProvider(configuration: config) super.init() provider.setDelegate(self, queue: nil) } }

Incoming Call Flow

When a VoIP push arrives, report the incoming call to CallKit immediately. The system displays the native call UI. You must report the call before the PushKit completion handler returns -- failure to do so causes the system to terminate your app.

func reportIncomingCall( uuid: UUID, handle: String, hasVideo: Bool ) async throws { let update = CXCallUpdate() update.remoteHandle = CXHandle(type: .phoneNumber, value: handle) update.hasVideo = hasVideo update.localizedCallerName = "Jane Doe" try await withCheckedThrowingContinuation { (continuation: CheckedContinuation<Void, Error>) in provider.reportNewIncomingCall( with: uuid, update: update ) { error in if let error { continuation.resume(throwing: error) } else { continuation.resume() } } } }

Handling the Answer Action

Implement CXProviderDelegate to respond when the user answers:

extension CallManager: CXProviderDelegate { func providerDidReset(_ provider: CXProvider) { // End all calls, reset audio } func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) { // Configure audio, connect to call server configureAudioSession() connectToCallServer(callUUID: action.callUUID) action.fulfill() } func provider(_ provider: CXProvider, perform action: CXEndCallAction) { disconnectFromCallServer(callUUID: action.callUUID) action.fulfill() } }

Outgoing Call Flow

Use CXCallController to request an outgoing call. The system routes the request through your CXProviderDelegate.

func startOutgoingCall(handle: String, hasVideo: Bool) { let uuid = UUID() let handle = CXHandle(type: .phoneNumber, value: handle) let startAction = CXStartCallAction(call: uuid, handle: handle) startAction.isVideo = hasVideo let transaction = CXTransaction(action: startAction) callController.request(transaction) { error in if let error { print("Failed to start call: \(error)") } } }

Delegate Methods for Outgoing Calls

extension CallManager { func provider(_ provider: CXProvider, perform action: CXStartCallAction) { configureAudioSession() // Begin connecting to server provider.reportOutgoingCall( with: action.callUUID, startedConnectingAt: Date() ) connectToServer(callUUID: action.callUUID) { provider.reportOutgoingCall( with: action.callUUID, connectedAt: Date() ) } action.fulfill() } }
