What happens if I do not renew my membership?
If your iOS Developer Program membership expires, your apps will no longer be available on the App Store and you will not be able to submit new apps or updates. You will lose access to pre-release software, the Apple Developer Forums, Certificates, Identifiers & Profiles, and Technical Support Incidents. However, you will still have access to iTunes Connect and free development resources.
