I have a small, simple iOS project that doesn't use a lot of memory or libraries or anything.
If I open my iOS project in XCode and run it on the iPhone 17 simulator, my memory consumption (as seen in Activity Monitor) goes into the yellow zone.
Granted, I have some other apps open (Safari, Mail, Messages, the usual stuff that people run) but nothing especially demanding. Without XCode and the Simulator running, my memory consumption is only around 25% on the Activity Monitor graph.
Is this expected behavior with Tahoe and iOS 26?
I was able to work on my project without running out of RAM on this same computer for the past 4 years no problem. Now it seems I have a problem.
