dsc_extractor can't extract symbol files from iOS 15.0

[envestcc]

i have downloaded iOS 15.0 fireware.
i followed the steps. when i run dsc_extractor , the result is as bellows:

dyld_shared_cache_extract_dylibs_progress() => 0

it seems to be not found any symbol files.

information of my mac
os version: 11.0.1
xcode: Xcode 12.5.1 Build version 12E507

yeah same issue for me. Also, if we open the dmg file now (Step 6) it leads to these 3 files which are now different from older ios versions
dyld_shared_cache_arm64e
dyld_shared_cache_arm64e.1
dyld_shared_cache_arm64e.symbols

and accordingly I guess the parsing needs to change

I tried both with Xcode 12, 13 for ios 15 symbol files but failed.

I update Xcode to Xcode 13 and i extract it successfully. Seems that it need a new bundle file in Xcode 13:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/usr/lib/dsc_extractor.bundle

you can use this tool

it can simply extract symbol files by this command

ipsw dyld split [cache_file]

ipsw dyld extract [cache_file]

Hey thanks for the help.
But I couldn't find the where those symbol files extracted even though I gave output folder path.

ipsw dyld extract ~/Desktop/Symbolfiles/15.1(19B74)/iPhone14,2_15.1_19B74_Restore.ipsw ./output

Please let me know if tried previously.

1. you need to extract the cache_file first

ipsw extract -d /Desktop/stack/15.0.2（19A404）/iPhone14,5_15.0.2_19A404_Restore.ipsw

2. then you will get some cache files, and you can extract symbol file from cache file

ipsw dyld split /Desktop/stack/15.0.2（19A404）/19A404__iPhone14,5/dyld_shared_cache_arm64e

sorry for telling u wrong command just now
