Apple’s iOS 15 And iPadOS 15 Will Let Apps Ask For More Than The Standard Amount Of RAM

When Apple releases iOS 15 and iPadOS 15 to the world later this fall it will give developers the opportunity to have their apps request more RAM than would previously be available.

Today, apps are only able to access a limited amount, but that’s all going to change.

Currently, apps are limited to only being able to access 5GB of RAM at any one time. With the new M1 iPad Pro coming with 16GB of RAM on board, that is now being extended.

Add this entitlement to your app to inform the system that some of your app’s core features may perform better by exceeding the default app memory limit on supported devices. If you use this entitlement, make sure your app still behaves correctly if additional memory isn’t available. An increased memory limit is only available on some device models. Call the os_proc_available_memory function to determine the amount of memory available. Higher memory use can affect system performance

It seems likely that Apple will still limit the amount of RAM used per app, but that the limit will change depending on the device in question. Those with more RAM will be allowed to allocate more to individual apps, for example.

Apple is currently testing iOS 15 and iPadOS 15 as part of a developer beta. It’ll be made available to everyone this fall and that’s when we’ll be able to see these changes in action.
