I have swift based app with NewRelicAgent.framework integration...
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Register the analytics app
NewRelicAgent.startWithApplicationToken("AA****************************6");
The app crashes on LoginViewController, first view controller on launch, with following log -

LoginViewController is subclass of common ZViewController....
class ZViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
}
class LoginViewController: ZViewController {
...
...
}
I don't have any other code related to NewRelicAgent in any of my view controller or in project (except the RunScript in project target).
Any idea to resolve it?
EDIT: With FIX :)
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Register the analytics app
NewRelicAgent.enableFeatures(NRMAFeatureFlags.NRFeatureFlag_SwiftInteractionTracing);
NewRelicAgent.startWithApplicationToken("AA****************************6");
// Your app specific code.......
}
// Add 'dynamic' before viewDidLoad method and probably any other view life cycle method or method to be traced for analytics
class ZViewController: UIViewController {
override dynamic func viewDidLoad() {
super.viewDidLoad()
// Your implementation...
}
}
Swift apps require some additional configuration in New Relic:
Have you added the dynamic declaration modifier to your methods and enabled Swift Interaction traces using the feature flag?
