Programmatically retrieve memory usage on iPhone

Question

I\'m trying to retrieve the amount of memory my iPhone app is using at anytime, programmatically. Yes I\'m aware about ObjectAlloc/Leaks. I\'m not interested in those, only

Swift solution of Jason Coco's answer:

func reportMemory() {
    let name = mach_task_self_
    let flavor = task_flavor_t(TASK_BASIC_INFO)
    let basicInfo = task_basic_info()
    var size: mach_msg_type_number_t = mach_msg_type_number_t(sizeofValue(basicInfo))
    let pointerOfBasicInfo = UnsafeMutablePointer.alloc(1)

    let kerr: kern_return_t = task_info(name, flavor, UnsafeMutablePointer(pointerOfBasicInfo), &size)
    let info = pointerOfBasicInfo.move()
    pointerOfBasicInfo.dealloc(1)

    if kerr == KERN_SUCCESS {
        print("Memory in use (in bytes): \(info.resident_size)")
    } else {
        print("error with task info(): \(mach_error_string(kerr))")
    }
}
