Compiling under XCode 8.3.3 for iOS 10+
I created a universal binary as outlined using the following script:
libtool -static arm64/libchilkatIos.a armv7/libchilkatIos.a armv7s/libchilkatIos.a -o libchilkatIos.a
It builds a resulting .a file. I then add that .a file to my project and an archive for submission using "Generic iOS Device".
When I perform the archive build I get the following error: ld: warning: ignoring file /Users/blah/directory/ChilKat/lib/arm64/libchilkatIos.a, file was built for archive which is not the architecture being linked (armv7): /Users/blah/directory/ChilKat/lib/arm64/libchilkatIos.a
