Hey, I am trying to run Swift 3 HelloWorld app ( HelloWorldSwift <https://github.com/aerogear/aerogear-ios-cookbook/tree/master/UnifiedPush... ) but I have a problem with the self-signed certificate. Looking at the documentation ( ios troubleshooting <https://aerogear.org/docs/unifiedpush/aerogear-push-ios/guides/#troublesh... ) and changing it a little bit for Swift 3 , I added in my DeviceRegistration.swift file the method: But it still doesn't work. The method is not invoked at all. Do I miss something? Any help will be appreciated.
