Hello @imadaboulhouda, Please refer to these links, I am sure they’ll help you:

You use WIndows or Mac?

I use windows and mac

With Apple you need an Apple Developer account - and you need to create certificates, create mobile provisions etc…

Have you been through that process?

Hello @imadaboulhouda, follow official link to deploy app to iOS:
