Unsupported file format

[anranziruo]

system:macOS
object library version:0.29.0
open local dSYM file occur error:Unsupported file format,i find the file has two architecture,(armv7,arm64),another file only one
architecture can work well

Does the objdump example work on the file?

This sounds like FileKind::parse is returning FileKind::MachOFat32 or FileKind::MachOFat64, and File::parse is failing because it does not support that. This is expected behaviour: you need to use FatHeader::parse_arch32 or FatHeader::parse_arch64 for these files, since they contain multiple architectures. The code in the objdump example shows how you can parse these files.

sorry,in object version 0.29.0 ,arch.architecture() this method has no exist

The objdump code that I linked is version 0.29.0, so it does exist. The architecture method is from the FatArch trait. You'll need to use that trait, as done in the objdump example.
