Does the default assets folder has target name twice
'<(PRODUCT_DIR)/<(_target_name)/<(_target_name)/assets'?

Done.

Nice, does this mean now it is possible to have different manifests for
different channels, rather than a custom on the fly script that does a git reset
--hard :).

Yes, I believe so.
