Simulated depth confidence: 94% at 12m. Generating synthetic bokeh with 6 layers.
Open Xcode and go to Settings (or press Cmd + , ).
If your app tries to allocate more than 9.5GB, the simulator doesn’t crash—it triggers a simulated and kills background tasks with a new log message: xcode iphone 17 simulator

If the iPhone 17 has just been announced, you likely need the latest Xcode beta or the latest public release. Simulated depth confidence: 94% at 12m
If the runtime isn't already included in your Xcode download, you can add it manually:
To get the running in Xcode , you'll need a version of Xcode that supports iOS 19 (the likely operating system for that model). Since iPhone 17 and iOS 19 are upcoming releases, you will generally find these in Xcode beta versions released during Apple's summer developer cycle. How to Install the Simulator If your app tries to allocate more than 9
Running the iPhone 17 simulator (even the fictional one) makes one thing painfully clear: we are no longer simulating phones. We are simulating .
The iPhone 17’s big leap isn’t a foldable screen or under-display Face ID. It’s —the idea that the phone is always recording spatial context, always running a lightweight LLM, always adjusting the radios. The simulator reflects that by being impossible to truly “quit.” Even after you stop a debug session, the simulated iOS kernel idles in the background, using 2% of your Mac’s CPU to maintain a fake Bluetooth state.
When enabled, the simulator runs your app perfectly for 90 seconds. Then, it starts dropping frames, dimming the simulated display, and slowing Metal shaders to 30% speed. A toast appears: “Simulated thermal peak reached. Your app would be throttled on-device.”
