Before you can publish your iOS app, you’ll need an Apple Developer Account.
Check if you already have one
Go to the Apple Developer Program enrollment page.
Sign in with your Apple ID.
If you can see a message saying you are already enrolled, or if you can access the Apple Developer Account dashboard with membership details, then you already have a Developer Account.
If you are prompted to enroll and pay the $99/year membership fee, it means you don’t have one yet.
