Assuming you mean Xcode, you can run Xcode on a Mac but not on an iPhone. There is no Xcode app for iPhone. You can develop apps inside Xcode and deploy them to an iPhone.
I made Xcode Xcord due to my mistake.
I'm sorry.
Thank you very much for your answer.
From Submitting apps to the App Store:
Xcode provides an integrated workflow for Apple Developer Program members to prepare and submit apps to the App Store. To submit your apps, use the latest version of Xcode available on the Mac App Store or, when available, the latest Release Candidate from the Downloads page.
