Every bridge function you write MUST follow this exact pattern:
import Foundation
enum {Namespace}Functions {
/// Brief description of what this function does.
///
/// - Parameters:
/// - paramName: Description of parameter
///
/// - Returns: Dictionary containing:
/// - resultKey: Description of return value
class FunctionName: BridgeFunction {
func execute(parameters: [String: Any]) throws -> [String: Any] {
// 1. Extract and validate parameters
guard let param1 = parameters["param1"] as? String else {
return BridgeResponse.error(code: "INVALID_PARAMETERS", message: "param1 is required")
}
// 2. Perform the native operation
do {
let result = try performOperation(param1)
// 3. Return success response
return BridgeResponse.success(data: [
"result": result
])
} catch {
return BridgeResponse.error(code: "OPERATION_FAILED", message: error.localizedDescription)
}
}
}
}
BridgeResponse is a real helper object built into NativePHP's iOS bridge.
ALWAYS use:
return BridgeResponse.success(data: ["key": "value"])
return BridgeResponse.error(code: "ERROR_CODE", message: "Error message")
IMPORTANT: iOS BridgeResponse.error ALWAYS requires both code and message parameters.
NEVER return plain [String: Any] directly. The official NativePHP plugin stubs use BridgeResponse. This is the correct pattern.

Plugins that need to respond to iOS AppDelegate lifecycle events should subscribe to NativePHP's NotificationCenter events:
import Foundation
import UIKit
/// Singleton delegate that subscribes to AppDelegate lifecycle events
class MyPluginDelegate: NSObject {
static let shared = MyPluginDelegate()
private override init() {
super.init()
setupNotificationObservers()
}
private func setupNotificationObservers() {
// Subscribe to APNS token registration
NotificationCenter.default.addObserver(
self,
selector: #selector(handleDidRegisterForRemoteNotifications(_:)),
name: Notification.Name("NativePHP.didRegisterForRemoteNotifications"),
object: nil
)
NotificationCenter.default.addObserver(
self,
selector: #selector(handleDidFailToRegisterForRemoteNotifications(_:)),
name: Notification.Name("NativePHP.didFailToRegisterForRemoteNotifications"),
object: nil
)
}
@objc private func handleDidRegisterForRemoteNotifications(_ notification: Notification) {
guard let deviceToken = notification.userInfo?["deviceToken"] as? Data else { return }
let tokenString = deviceToken.map { String(format: "%02x", $0) }.joined()
UserDefaults.standard.set(tokenString, forKey: "my_plugin_push_token")
LaravelBridge.shared.send?(
"Vendor\\MyPlugin\\Events\\TokenReceived",
["token": tokenString]
)
}
@objc private func handleDidFailToRegisterForRemoteNotifications(_ notification: Notification) {
if let error = notification.userInfo?["error"] as? Error {
print("Failed to register: \(error.localizedDescription)")
}
}
}
Available Notifications:
NativePHP.didRegisterForRemoteNotifications - APNS token received (["deviceToken": Data])NativePHP.didFailToRegisterForRemoteNotifications - Registration failed (["error": Error])NativePHP.didReceiveRemoteNotification - Remote notification receivedNativePHP.didFinishLaunching - App finished launchingNativePHP.didBecomeActive - App became activeNativePHP.didEnterBackground - App entered backgroundThe delegate can also conform to iOS protocols like UNUserNotificationCenterDelegate and MessagingDelegate.
