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.

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
