Pushes compiled BEAM files from _build/dev/lib/*/ebin/ to connected devices.

Does NOT rebuild APKs or recompile native code — that's deploy.sh (first-time setup). Use this for day-to-day code iteration: edit Elixir → mix dala.deploy → code running.

Transport selection

Erlang dist (preferred): when a device node is already reachable via Erlang distribution, BEAMs are hot-loaded via RPC. No restart needed — modules are loaded in place exactly like nl/1 in IEx.

adb push / cp (fallback): when no dist connection exists (first deploy, app not running), falls back to the traditional push-then-restart path.

Platform behaviour

Android: pushes via adb push (requires adb root, i.e. emulator or debug build), or falls back to adb push → /data/local/tmp/ → run-as tar xf for real devices.

iOS simulator: copies files locally into /tmp/otp-ios-sim/beamhello/ (no network hop — the simulator shares the Mac filesystem).
