Answer 1

Finally solved after about 1.5 day, the TicketViewController.m file was added twice (duplicate) in the project Build phases >> Compile Sources, just removed one of them and the error is gone now, thank you very much @MQLN for your support

Answer 2

Your error means that for some reason or another, your pod is getting copied twice.

I'm assuming you've read the docs for how to add a bridging header, if you are still using libraries written in Obj-c.

If you didn't do anything wrong in your code (like accidentally copy files from a pod over manually, and then try and use a pod! I've messed this up before, it happens.) this error most often goes away by cleaning your project and then deleting derived data.
