Out of nowhere I got some red banner on top of my iPhone 13 mini / iOS 17.5. I cannot pin point the root cause of this. What I can say is that it only happens to Simulators of a certain type, e.g. iPhone 12 and 13 mini, but not iPhone 14 for example.

I have installed Xcode 26.1.0 and 26.1.1, out of which 26.1.0 is selected:

$ xcode-select -p
/Applications/Xcode-26.1.0.app/Contents/Developer

And following runtimes:

$ xcrun simctl runtime list
== Disk Images ==
-- iOS --
iOS 17.5 (21F79) - CF933623-A258-44F8-B248-C0F25C0C343B (Ready)
iOS 26.1 (23B80) - D11C3CDC-EE3D-44CC-8B92-9B7D00B54B0B (Ready)

Total Disk Images: 2 (14.6G)

Installing the newer 26.1 23B86 runtime doesn't help either.

January 2026 and this is still happening on 13 mini simulator. Latest xcode version (not beta).

Yesterday, January 14, I installed Xcode 26.2 from XcodeReleases. The issue is still present on iPhone 12 mini and iPhone 13 mini devices.

@hova414 @shamil_a the fix from @enzox fixed it for me. Go to Settings → Developer → Display Zoom (View), set it to Larger Text, and then back to Default.

Reporting this as still an issue as well. The red RDAR bar is still present and the app being tested on the Simulator zooms in incredibly far. No system apps are affected.

The workaround until this is fixed is to change the display zoom in Settings > Developer to Large Text and then revert back to normal. You will need to do this every time you reboot the simulator for iPhone 12+13 Mini on any iOS version.

@Elmar0903 I would recommend you to reinstall the latest Xcode Version to make sure downloads the latest simulators.
