I submitted a similar question in 2021 for Xamarin.iOS: "Xamarin.iOS: Where do I find the namespace containing wrapper for function os_proc_available_memory() in Apple's "OS" framework?"
The answer at that time was that particular API is not exposed in Xamarin.iOS.
Today's question is for .NET Maui, and I added "or equivalent" to the question in case there is some other API for iOS to accomplish the same thing. The documentation for os_proc_available_memory() says: "Call this function to determine the amount of memory available to your app."
Thank you.

There isn't a direct equivalent of the os_proc_available_memory() function from the Unix/Linux os module available on iOS. iOS development usually involves using the Objective-C runtime and the iOS SDK.
To monitor memory usage and availability on iOS, you would typically use a combination of APIs provided by Apple's frameworks. You might be interested in checking out the mach_task_basic_info API or the task_info API from the mach and mach/task_info.h headers, respectively.
Thank you for the information. How do I access those APIs (mach_task_basic_info API or the task_info API) from within .NET Maui?

You need a binding project. Maui uses the mono binding tools.

currently Maui can only call objective-c apis.

note: iOS uses the Mach kernel.
Thank you for the answer! I have not reviewed yet, but I assume this will be what I need.
