Apple is making 64-bit support mandatory for all software uploaded to the App Store from February, according to Digital Spy.
The Cupertino firm entered the 64-bit smartphone game last year with the release of the iPhone 5S, but many software developers remain in 32-bit territory.
Under the new terms and conditions, all new apps and updates to existing software must be created using the iOS 8 SDK.
Although the move may irk some software developers, the move to an all-64-bit system will yield benefits for users, who are likely to see faster and smoother apps hitting their devices.
Apps will continue to support 32-bit hardware from February, but will be rejected unless 64-bit optimisation is also in place.
Apple will release new tablet hardware this week in the shape of the iPad Air 2 and the iPad Mini 3.
