A valid provisioning profile for this executable was not found… (again)

Question

I know this has been asked and answered multiple times but I\'m tearing my hair out as none of the proposed solutions appears to work.

Answer 1

I have spent about a week solving this problem. Most of the answers are sort of magic (no logical purposes for these algorithms) and they were not useful for me. I found this error in Xcode console:

ERROR ITMS-90174: "Missing Provisioning Profile - iOS Apps must contain a provisioning profile in a file named embedded.mobileprovision."

And found this answer solving this issue. The case is to switch Xcode Build system to the Legacy one.

I was deploying my Ionic app.
