Binaries compilation with lipo

1. Build the FastPdfKit-iphoneos target for Any iOS Device. Grab the generated libFastPdfKit-iphoneos.a binary or save its path.
2. Build the FastPdfKit-iphonesimulator target for any simulator in the list. Grab the generated libFastPdfKit-iphonesimulator.a binary or save its path.
3. Open the terminal and use the following command:

lipo -create IPHONEOS_PATH SIMULATOR_PATH -output FAT_DEST_PATH

where IPHONEOS_PATH is the binary path obtained at step 1, SIMULATOR_PATH is the path obtained at step 2 and FAT_DEST_PATH is the destination path for the fat library.
