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
You can use otool to inspect the library file. With some experimentation I found that the flags -lv gave me useful output. Open up a terminal window and switch to the directory your library is in:
cd /path/to/parent/directory
(Hint: you can drag the icon from the title bar of a finder window into the terminal and it will enter the path for you). Then type the following command:
otool -lv myStaticLibrary.a | less
In less, type / (search) and then LC_VERSION_MIN_IPHONEOS. You should see something like this:
Load command 1
cmd LC_VERSION_MIN_IPHONEOS
cmdsize 16
version 7.0
sdk n/a
The deployment target should be the value next to version.
