iOS 15 RAM administration has improved. Now apps like Procreate can request entry to extra reminiscence on units just like the M1 iPad Professional with 16GB RAM.


  • iOS and iPadOS 15 expose apps to extra reminiscence on sure units
  • At present, apps are restricted to only 5 gigabytes of RAM
  • Apps like Procreate will run higher on iPads sporting further RAM

Procreate will profit from utilizing extra RAM on units just like the M1 iPad Professional

iOS 15 RAM administration lets apps transcend 5GB

Apple’s iOS 15 and iPadOS 15 will carry main efficiency enhancements to sure iPad apps like Procreate by letting builders request entry to extra RAM when the updates drop this fall.

Apple’s cellular working programs don’t use digital reminiscence, limiting apps to 5 gigabytes of reminiscence even when the quantity of bodily reminiscence is larger.

For apps like Procreate, this implies customers don’t get to make use of extra layers when creating illustrations even when they run the app on a tool just like the M1 iPad Professional with 16GB of RAM, the best quantity of RAM to date in an iOS machine.

Fortunately, Apple has determined to do one thing about it.

Within the second betas of iOS and iPadOS 15, Apple added a brand new entitlement to allow builders to request entry to extra reminiscence on “supported units,” in line with developer documentation on the Apple web site.

Apple doesn’t specify supported units, however is secure to imagine that the corporate might be referring to the M1 iPad Professional, which comes with both eight or sixteen gigabytes of reminiscence.

For apps that do want extra RAM, this will lead to higher efficiency.

Add this entitlement to your app to tell the system that a few of your app’s core options might carry out higher by exceeding the default app reminiscence restrict on supported units. Should you use this entitlement, ensure your app nonetheless behaves accurately if extra reminiscence isn’t accessible.

It’s good to see Apple addressing the present restrictions in iPadOS that maintain again the M1 iPad Professional from reaching its true potential when working professional apps.

Does iOS swap reminiscence with the disk?

Reminiscence swapping or paging refers to swapping chunks of the RAM with flash storage when reminiscence runs low. Many working programs use reminiscence swapping to let apps exceed the dimensions of obtainable bodily reminiscence. However iOS and iPadOS don’t assist swapping like macOS does on account of constrained sources (fixed paging consumes energy).

Moderately than implement digital reminiscence through paging, iOS aggressively manages the RAM, purging apps that you just haven’t used shortly. Such limitations have compelled builders of pro-graded iPad apps like Procreate to optimize their code for low reminiscence conditions.

With builders now capable of request entry to extra RAM on sure units just like the M1 iPad Professional, we might lastly see apps like Pixelmator Professional or Ultimate Lower Professional being ported to iPad.
