Update!
I can still not send push notifications to iOS, sadly.
I have tried to create 2 apps in Xcode, one uses APNs to send local push notifications with the same certificate that I use in AwareIM, which works without any issues and the second app uses Firebase to send notifications to iOS, which I personally like more. Furthermore, I would like to have the choice to use Firebase for both iOS and Android, to be able to send mass notifications to every user trough Firebase is very useful, and to only use one notification hub makes it all much neater and simpler.
Because it works in Xcode with the same certificate (p.12) it has to be in AwareIM that I am doing something wrong or maybe there is a bug.
To create notifications, I have followed both the AwareIM video guide (https://www.yo ut ube.com/watch?v=VwQyZ2oCvC0) and the how-to written guide multiple times without any improvements.
If it helps, I am using Monaca to publish the apps I have created.
I have tried with and without sandbox mode on in AwareIM, I have also tried debug builds and have published the app to TestFlight trough Monaca.
I have tried to use Ionic but have not even been able to load the AwareIM mobile files into Ionic without errors, so Monaca seems to be the easiest to just upload and publish from in my experience.
Also, in AwareIM you aren't able to do nearly as much with notifications as you are able to with "normal" programming. Title, Body, Sound, IOSbadge are the only things you can change in AwareIM, which is enough, but still disappointing. Maybe the Body function can send pictures, if not that is something I would like to be able to send in the future.
I am linking to a very simple test BSV if anyone wants to check it out.
