I believe this is because it's no longer possible to compile without thumb support -- If anyone is interested in rewriting these as THUMB instructions, I'm certainly open to PRs.
It's also possible that you're attempting to compile for ARM64 - this example only works with ARMv7s. You'd have to rewrite most instructions to properly work with ARM64.
A bit late, but seeing this issue as well on macOS 10.13.3, using xCode 9.2.
I'm attempting to compile with ARMv7s, but no luck. Haven't had a chance to play around with it, but will take a look and if I come up with anything new, I'll post here.
