# By default, iOS executables are fat binaries that contain armv7 and arm64
# build artifacts. This is suitable for release builds and for testing on
# older devices. However, generating fat binaries takes a very long time, and,
# depending on the application type, may be unnecessary. If the type of
# architecture is known beforehand, setting that as the active arch will
# greatly reduce build times and reduce binary sizes.
