But the Ts & Cs of being an Apple registered developer (which you need to be in order to become an iOS app developer state that):
You certify that you are of the legal age of majority in the jurisdiction in which you reside (at least 18 years of age in many countries) and you represent that you are legally permitted to become a Registered Apple Developer.
Unless otherwise agreed or permitted by Apple in writing, you cannot share or transfer any benefits you receive from Apple in connection with being a Registered Apple Developer. The Apple ID and password you use to login as a Registered Apple Developer cannot be shared in any way or with any one. You are responsible for maintaining the confidentiality of your Apple ID and password and for any activity in connection with your account. Notwithstanding the foregoing restrictions in this Section 1, if you are the parent or legal guardian of individuals between the ages of 13 and the legal age of majority in the jurisdiction in which you reside, you may allow such individuals to share your Apple ID and password for their use solely under your supervision and only in accordance with this Agreement. You are responsible for such individuals’ compliance with and violations of this Agreement and any other Apple agreements.
So, in essence, your parents have to be the 'Developer', and you can share their credentials. Your "parents" will need to submit the app to the App Store, etc.
