Unable to download the latest iOS 18 beta simulator (cryptexDiskImage)

Hello,

I'm trying to download the latest beta simulators that Apple just released, but it seems something has changed. Below is the error message I'm receiving.

Yeah, unfortunately the changes with new simulators use an internal Apple system framework and the Pallas Apple service to fetch the simulator download. So it may be some time before (or if) the new simulator types can be supported in this tool :/

[timsutton]

Looking into it a bit more, it seems like since ipsw already has all the support for OTA fetching, that adding simulator support to ipsw makes more sense, and to sunset speedwagon.

@timsutton Thank for the detailed information! They also removed the Export Disk Image command in Xcode 16.

UPDATE: Just noticed that there is a simulator runtime export/import feature in Xcode 16.
