Lipo command merges the static library of the emulator and the real machine

iOS development, static libraries often need to use two sets of the simulator, one set is the iOS real machine, these two sets of architectures are not the same. Plus Debug and release, then the 2*2=4 set.

But we can use Lipo to merge static libraries, such as

Lipo-create release-iphoneos/lib123.a debug-iphonesimulator/lib123-output lib123.a

Then use Lipo-info to see that this is a FAT file and contains all the required schemas. The library is automatically selected when Xcode is compiled
