Check iOS deployment target of a static library

Question

I have many static libs like libBlah.a With file tool I can check supported architectures. (arm64 or i386)

Is there tool to check iOS Dep

Answer 1

The target OS version is encoded in the LC_VERSION_MIN_IPHONEOS load command in the MachO header of the static library. You can see it via:

otool -l mylib.a | grep -A 3 LC_VERSION

Example output:

      cmd LC_VERSION_MIN_IPHONEOS
  cmdsize 16
  version 9.0
      sdk n/a
