I am building an app that will allow users to share their views. In the view there is a list which contains the information. To share the view, I convert the view into a shareable PDF file with ImageRenderer. But when the file is shared, the list with the information is gone. How can I fix this to show the list inside the PDF file?

I am developing a messaging app. Currently when the sender sends a message the senders phone receives notification of the message that was sent. Obviously it should be the receiver who receives this notification. Not sure what I'm doing wrong - can anyone help with this problem?

Is there any way for part of the app to always run in the background so when the user opens the app it will be updated.

I am trying background fetch so my app will update every once in a while so the user will get updated information. How will I be able to do this.

Is there any way that I can run my app in the background so when the user opens the app they will be able to see the messages straight away instead of waiting seconds for it to load.

While I am on the app I can receive local notifications once a new message is posted. But when I am off the app and in the background and there is a new message I do not receive any notifications. How can I run my application in the background so I always will be able to receive messages to send notifications while not being on the app.
