access Additional data in func didReceive(_ notification: UNNotification) {

[appcelerate]

How can I access in
func didReceive(_ notification: UNNotification) {
the additional data from the payload?

@appcelerate You should setup a OSHandleNotificationActionBlock block which will give you a Object where this has been parsed for you. See initWithLaunchOptions for an example of setting one up.

@appcelerate if you still need it:

guard let customData = notification.request.content.userInfo["custom"] as? Dictionary<String,Any> else { return }
guard let oneSignalAdditionalData = customData["a"]  as? Dictionary<String,String> else { return }

Remember! Additional data is always [String: String]
