# Build a native-sdk mobile embed static library for the iOS simulator,
|
|
# link it into the minimal ObjC presentation shim (main.m), assemble an
|
|
# .app bundle without an .xcodeproj, then install + launch it on a booted
|
|
# simulator and verify a non-blank screenshot.
|
|
#
|
|
# Usage:
|
|
# ./run.sh # mobile-canvas on "iPhone 15"
|
|
# ./run.sh --example-dir ../../ui-inbox --build-arg -Dmobile=true
|
|
# ./run.sh --device "iPhone 15 Pro" --shutdown
|
|
# ./run.sh --build-only # stop after the .app bundle
|
|
# ./run.sh --estimator-text-metrics # estimator instead of CoreText
