Logs

Stream a running device's system logs without reopening Metro.

simgrid logs              # one session → straight to it; several → picker
simgrid logs "iPhone SE" # match a device by name (or id)

Run it from the project directory — simgrid looks at that project's running sessions.

What it runs

PlatformUnder the hood
iOS simulatorxcrun simctl spawn <udid> log stream --level=debug --style=compact (filtered to the app when its name is known)
Android emulator / deviceadb -s <serial> logcat
Physical iOS devicenot supported yet — see below

Ctrl+C stops the stream; your app keeps running.

caution

Streaming the system log from a physical iPhone/iPad over USB isn't wired up yet — simgrid logs covers iOS simulators and Android emulators/devices.
