Doesn't really work when you're developing locally, tho. Can you imagine loading binaries from the cloud into your phone every single time?

I wirelessly deploy from Xcode regularly. It’s slower than cable-based deploys, but not much, and the convenience is worth it for me.

(Apple’s wireless deploys replace the cable, but I assume they do not happen over the cloud — both devices are on the same local network. I haven’t checked the network traffic, but I’d be surprised if the broader internet is involved.)

It is already works like this and works just fine.

At that point you drill out the sealed cover to the JTAG pins, a-la debugging the Apple Watch ;)
