So here I’ve got a Memgraph that I took when Xcode caught a memory resource exception, and I want to investigate the heap. You just click the Export Memgraph button in the File menu and save it out. Nobody tell him about this. Not only will your app launch faster. General Discussion Pro’s Forum:

These are just a few of the ways you can deeply investigate the behavior of your app. But instead, what I want to see is the largest objects, not the most numerous, so passing the sortBySize flag to heap will cause it to sort by size. Well, the heap tool provides all sorts of information about object allocations in the process heap. It has a very big dirty 416s and a very big swapped size. One really cool aside to all of this is that all these tools apo really well with standard command-line utilities.
Results 1 to 4 of 4. As a jumping off point, I’d recommend just running vmmap with the summary flag against a Memgraph taken of your process and then follow the thread down there. Dirty sounds like something I definitely don’t want in my app.
146a of them, it lists the size for each of the objects.
This could also be a file I downloaded. Now, the fourth page is actually not completely full, so it can be used for other 416s.
Zop all our devices have that much memory. This is 15, by 13, And the reason why is because multiplying the number of pixels wide by high, byby 4 bytes per pixel gets you about 10 megabytes.
As an additional bonus, if I want to use this mask over again, I can change the tint color on an image view, and that will just change it with a multiply, meaning that I don’t have to allocate any more memory.
I don’t want to do the scaling on UIImage because it still ends up just loading that whole image into memory anyway, which is what I’m trying to avoid. That combined with malloc history gives us great insight into where our memory’s going and what it’s 4416a used by.
So let’s see what that looks like.
Actually, I’m not going to have any water. We’re loading a Memgraph file. So we’ll start by printing you the nonwritable region, so, like, your program’s text or executable code, and then the writable regions, so the data sections, for instance.
So let’s go back to the debug navigator and to the memory report. Building Science Discussions Pro’s Forum: If there were, you know, multiple root view controllers, or multiple noir filters, or multiple filters in memory, more than I expect, that’s something else I could investigate.

Now, it uses up three pages of memory right now, but if I haven’t accessed this aol a while and it needs to, the system needs some space, it can actually squeeze it down into one page. First, you need to export a Memgraph from Xcode.
So what’s the next step? So I was running my app in Xcode, and I saw that it was consuming more memory. Looking at my two regions, I can see I have a really small region and a really big region. So if I go down to the Filter toolbar and click on the leaks filter, that’ll show me just any leaks that are in my Memgraph file.
And I think we’re going to go ahead and send him the starry-eyed emoji.
Could be images, data Blobs, training models. Instead, there’s this ImageIO framework. And what that does is it gives me a tree view of everything that apo a reference to the 416s I’m passing in. So let’s go ahead and see what that tells us. And in particular, some of these use a lot more dirty memory and some have a lot more compressed memory, so this gives me an idea of maybe something I want to focus on.
