FYI, latest version of Stack Wallet on TestFlight has added coin control in addition to BIP47 PayNyms a few releases prior:
Discussion
This is the first wallet to support PayNyms on iOS.
Waiting for a non-shitcoin wallet to offer paynyms.
BlueWallet is coming out with it soonish supposedly.
I find it hilarious that a shitcoin wallet beat BlueWallet to the punch. Especially since BW have talked about integrating it since a few years back, and Stack Wallet started developing it for their wallet it only a few months ago.
I've been liking Stack Wallet so far. The devs are receptive to feedback and actually ship code.
Cool. I actually downloaded it, but never tried yet
