Xcode ios memory monitor4/13/2023 ![]() The nice thing is that the UMA RAM is quite fast, although in my hands it is not as fast as Apple claims, but that's probably just my bad coding skills at work and not Apple's UMA. But at the same time, the same UMA RAM is employed for the CPUs, GPUs, and NEs, so if your application requires a huge amount of array space, then you have to take that into consideration as your UMA RAM is used for all three types of processors in addition to your array requirements. Also realize that the RAM on Apple Silicon is unified, the UMA is for the CPUs, GPUs, and NEs - thus minimizing the need for transferring/copying data among these engines. And realize that the SSD on the M1 Max is roughly twice as fast as the SSDs on most any other fast machine (7500MB/s versus <5000MB/s), thus swapping to SSD may perhaps be less noticeable to the user, although I suspect that any SSD makes swapping less noticeable to the user for most tasks. It will be not be my main priority for a while, but I really want to learn how to build an app to build one myself one day, so the machine I have should be able to do that.Ĭlick to expand.And I agree with wilberforce, only purchase what you require. I could afford the higher specced model, but I would prefer to save the money, since it would be almost 1.5x the price of the base model.Īnyway, since I am not experienced and just getting into software development, I would be very grateful if some of you with more experience in the field could give me a recommendation. I usually like to buy base models, just so I can upgrade a bit more often, and also because in my mind, they tend to have better value. I was initially hesitant to make that upgrade, since that would mean I would also want 1TB to really be able to keep the machine for a while, and also add the 10-Core M1Pro instead of the base 8-Core. Monitor your applications for memory leaks, which can cause unexpected results. You can also create your own Instruments using DTrace and the Instruments custom builder. The text is a little small in the screenshot, but it says the app is using 9. ![]() Since I am still in the return period with the MacBook, I was wondering if that meant I should go for 32GB of Unified Memory. Instruments The Xcode instruments allow you to dynamically trace and profile the performance of your Mac OSX, iPhone, and iPad applications. To determine how much memory your app is currently using, look at the Persistent Bytes column for the category All Heap Allocations. ![]() I have noticed though, that whenever I am coding in Xcode, my memory pressure is constantly yellow and I have swap usage of roughly 2-7GB. I have recently started learning SwiftUI on my 14 inch MBP base model.
