macOS Permissions

Critical Constraints

• ❌ DO NOT assume permissions are granted → ✅ Always check before using protected APIs
• ❌ DO NOT repeatedly prompt after denial → ✅ Guide user to System Settings instead
• ❌ DO NOT block the entire app on missing permission → ✅ Gracefully degrade, offer reduced functionality
• ❌ DO NOT forget PrivacyInfo.xcprivacy → ✅ Required for App Store submission

Permission Types

Accessibility Permission

import ApplicationServices

// Check without prompting
func isAccessibilityGranted() -> Bool {
    AXIsProcessTrusted()
}

// Check and prompt user (shows system dialog)
func requestAccessibilityPermission() -> Bool {
    let options = [kAXTrustedCheckOptionPrompt.takeRetainedValue() as String: true]
    return AXIsProcessTrustedWithOptions(options as CFDictionary)
}

// Open System Settings → Privacy → Accessibility
func openAccessibilitySettings() {
    NSWorkspace.shared.open(URL(string: "x-apple.systempreferences:com.apple.preference.security?Privacy_Accessibility")!)
}

Screen Recording Permission

import CoreGraphics

// Check (macOS 15+)
func isScreenRecordingGranted() -> Bool {
    CGPreflightScreenCaptureAccess()
}

// Request (macOS 15+)
func requestScreenRecording() -> Bool {
    CGRequestScreenCaptureAccess()
}

// Open Settings
func openScreenRecordingSettings() {
    NSWorkspace.shared.open(URL(string: "x-apple.systempreferences:com.apple.preference.security?Privacy_ScreenCapture")!)
}

Camera / Microphone

import AVFoundation

func checkCameraPermission() async -> Bool {
    switch AVCaptureDevice.authorizationStatus(for: .video) {
    case .authorized: return true
    case .notDetermined: return await AVCaptureDevice.requestAccess(for: .video)
    case .denied, .restricted: return false
    @unknown default: return false
    }
}

Graceful Degradation Pattern

struct FeatureAvailability {
    var canInsertText: Bool { AXIsProcessTrusted() }
    var canUseGlobalHotkey: Bool { AXIsProcessTrusted() }
    var canCaptureScreen: Bool { CGPreflightScreenCaptureAccess() }

    var degradedFeatures: [String] {
        var features: [String] = []
        if !canInsertText { features.append("Text insertion into other apps") }
        if !canUseGlobalHotkey { features.append("Global keyboard shortcuts") }
        return features
    }
}

struct PermissionBanner: View {
    let availability: FeatureAvailability

    var body: some View {
        if !availability.degradedFeatures.isEmpty {
            VStack(alignment: .leading, spacing: 8) {
                Label("Some features require permissions", systemImage: "lock.shield")
                    .font(.headline)
                ForEach(availability.degradedFeatures, id: \.self) { feature in
                    Text("• \(feature)")
                        .font(.caption)
                }
                Button("Open System Settings") { openAccessibilitySettings() }
                    .buttonStyle(.borderedProminent)
            }
            .padding()
            .glassEffect(.regular.tint(.orange), in: .rect(cornerRadius: 12))
        }
    }
}

Permission Onboarding Flow

struct OnboardingPermissionView: View {
    @State private var accessibilityGranted = AXIsProcessTrusted()
    let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()

    var body: some View {
        VStack(spacing: 20) {
            Image(systemName: accessibilityGranted ? "checkmark.circle.fill" : "lock.circle")
                .font(.system(size: 48))
                .foregroundStyle(accessibilityGranted ? .green : .orange)

            Text(accessibilityGranted ? "Permission Granted!" : "Accessibility Permission Required")
                .font(.title2)

            if !accessibilityGranted {
                Text("This app needs Accessibility access to insert text into other apps and register global shortcuts.")
                    .multilineTextAlignment(.center)

                Button("Open System Settings") {
                    requestAccessibilityPermission()
                }
                .buttonStyle(.borderedProminent)
            }
        }
        .onReceive(timer) { _ in
            accessibilityGranted = AXIsProcessTrusted()
        }
    }
}
