How do I prove I own/am the developer of an iOS app? I am currently in the process of trying to secure a visa for overseas work. I recently developed an iOS app and need to provide proof or ownership or that I developed it. Is there a way to go about this? Can Apple provide a certificate or something? Any advice on this would be really appreciated. Thanks!
Is you app available in App Store? Is your name officially mentioned there as the author. If yes, then I would consider this as a proof.

Are you talking about being iOS developer in general or developer of particular iOS app? If first case is true then maybe your certificates of employment could solve the problem?
