Q:
I need to verify that the latest version of the iOS PDFNet SDK supports 64-bit architectures. How can I do so?
A:
The easiest way is with xcrun:
$ unzip PDFNet_iOS-6.2.1.zip >/dev/null
$ cd PDFNet_iOS/Lib/PDFNet.framework/
$ xcrun -sdk iphoneos lipo -info PDFNet
Architectures in the fat file: PDFNet are: armv7 armv7s i386 x86_64 arm64
