I implemented a function to open an AlertView when I receive a remote notification like this:

func application(application: UIApplication, didReceiveRemoteNo

Method (Swift 4):

func extractUserInfo(userInfo: [AnyHashable : Any]) -> (title: String, body: String) {
    var info = (title: "", body: "")
    guard let aps = userInfo["aps"] as? [String: Any] else { return info }
    guard let alert = aps["alert"] as? [String: Any] else { return info }
    let title = alert["title"] as? String ?? ""
    let body = alert["body"] as? String ?? ""
    info = (title: title, body: body)
    return info
}

Usage:

let info = self.extractUserInfo(userInfo: userInfo)
print(info.title)
print(info.body)
