Hello everyone,
I recently contacted Apple Developer Support regarding access to an older iOS beta build (specifically iOS 26.0 Developer Beta 1, build 23A5260u for iPhone 15 Pro). Developer Support confirmed that they can’t provide access to previous betas and advised me to bring the question here.
My question: Is there any official or supported method for developers to reinstall or access older, unsigned beta builds for the purpose of testing compatibility or debugging legacy features?
I’m aware that Apple stops signing older versions once newer builds are released, but I’m wondering whether programs like AppleSeed, enterprise testing frameworks, or specific partner channels provide legitimate access to prior betas for regression or compatibility testing.
Any insights or referrals to Apple contacts, teams, or individuals who may be able to advise on this topic would be greatly appreciated.
Best regards, Xavo Nizer
