The specific format for status bar overrides changes every so often, and Apple decided to shift the layout over by one byte in the 16.1 runtime. Normally, these updates are handled transparently by CoreSimulatorBridge, which converts things under the hood for you.

They did so this time as well. There’s a class to handle the new format, “CSBStatusBarOverrides_iOS_Current”, and one that handles the older one, “CSBStatusBarOverrides_iOS_16”. The one that gets picked depends on the runtime your simulator is using, or SIMULATOR_RUNTIME_VERSION.

Unfortunately, the corresponding changes in UIKitCore to read the new layout aren’t in the simulator runtimes. CoreSimulatorBridge forwards the overrides over in 16.1+ format, but the simulator sees it as the old 16.0 format, and generally fails to set the status bar correctly.
