companion/project.yml disables code signing for the simulator build, so
the device build inherited it and produced an unsigned runner that the
device rejected at install (0xe8008018). build-for-testing now forces
CODE_SIGNING_ALLOWED/REQUIRED=YES so automatic provisioning signs it.
xcodebuild's -authenticationKeyPath requires an absolute path, but .env
files commonly carry a repo-relative one. Resolve it against the working
directory before the stat so a relative ASC_API_KEY_PATH still signs.
iosDeviceChecks now verifies devicectl, iproxy on PATH, a connected+paired
device (via ios.ConnectedDevices), and App Store Connect signing creds (via
ioscompanion.VerifyDeviceSigning). The retired JVM sidecar checks stay only
under android.
NewDevice reuses Driver with d.companion set to the runner dialed over an
iproxy usbmux tunnel, hybrid=false, runnerClient=nil. The existing accessor
seams then route launch/snapshot/text/gesture to the runner with no new
DeviceDriver methods. Device seams swap clear-state to a devicectl
reinstall, container reset to a warn-once no-op, and paste grant to a no-op.
realSpawnDeviceRunner builds and signs the runner at run time via the App
Store Connect API key (no Xcode UI), caching on a source hash.
