[iOS 18] ipsw dyld imports aborts with EOF

[lukbukkit]

I'm using the ispw dyld imports command to search for all imports of a given framework / library. I just noticed that the command does not work with the dyld_shared_cache_arm64e of iOS 18.

# iOS 17.1.1 (21B91__iPhone15,4)
$ ipsw dyld imports dyld_shared_cache_arm64e Accelerate

Accelerate Imported By:
=======================

In DSC (Dylibs)
---------------
[...]

In FileSystem DMG (Apps)
------------------------
[...]

# iOS 18 (22A5282m__iPhone16,2)
$ ipsw dyld imports dyld_shared_cache_arm64e Accelerate

Accelerate Imported By:
=======================
Usage:
  ipsw dyld imports <DSC> <DYLIB> [flags]

Aliases:
  imports, imp

Flags:
  -h, --help          help for imports
  -i, --ipsw string   Path to IPSW to scan for MachO files that import dylib

Global Flags:
      --color           colorize output
      --config string   config file (default is $HOME/.config/ipsw/config.yaml)
      --no-color        disable colorize output
  -V, --verbose         verbose output

   ⨯ failed to get dylibs that import /System/Library/Frameworks/Accelerate.framework/Accelerate: EOF

Am I doing something wrong, or is this a novel issue with the dyld cache of iOS 18? Thanks for building such great iOS tooling :)

Best

looks like a decent amount of changes in iOS 18. made a feat branch feat/prebuilt_iOS18

Just an update, I've merged the branch as a FIX PR for now, so that it properly errors for people and fixes the ipsw dsc imports fall-back to just scanning DSC dylib LCs

@lukbukkit this should be fixed in latest now.
