I’m not even sure a grant is necessary. As the author, you can relicense your work whenever you want. That includes relicensing for a certain platform. So, release your GPLv3 source code, but release the “proprietary” version on the App Store.

If you're the sole author yes. If you took any contributions then no unless you got all the contributors to accept your proprietary license for their contribution.
