I am thinking about building a rocket with deployable wings like Tiling's design, only I want the wings facing forward during powered ascent. I hope to deploy them at apogee. But at wing deployment, I think that I will also need canards in the front like the Edmonds CICI design.
Uh....hmm. If the wings are swept forward for boost, the launch Center of Pressure will be very far ahead of where it will be for glide. If you add so much noseweight that it is stable on boost, then it will be fatally nose-heavy for glide. If you do not add plenty of noseweight in order to keep the glide CG correct, then it will be fatally unstable on boost.
This is the opposite of a normal swing-wing rocket boosted glider, where having the wing back for boost makes the model's CP move a lot behind the CG and so it is extremely stable, then when the wings deploy, the CP moves a lot closer to the CG for proper glide trim (if the CG was set up right to begin with)
Another issue with having the wings swept forward, is that the oncoming airflow is going to pry on the wings and bend the "tip" of the wing (up front on boost) out of parallel with the body/fuselage. An effect of Aeroelastic Divergence -
https://en.wikipedia.org/wiki/Aeroelasticity#Divergence
At the least, that would act like a canard "up elevator" (or down elevator) to pitch it into a loop or half-loop. Or, the wing will bend too far and snap (or flutter/shred). So, you'd need to add some horizontal guides (like dowels) sticking out sideways from the fuselage to trap the wings so the forward tips could not bend like that.
Back to swing-wings, here is a link to a thread I started on TRF long ago, including a lot of photos:

And this is an article I wrote with tips for B sized Rocket Gliders, which includes some info on SwingWing Gliders:

Which includes this:
Here's a photo of a 6.5 foot span swing-wing that I added rudder-only R/C to:
And this video clip, from a old 8mm movie shot in 1976, showing another 6.5 foot swing wing boosting, and deploying. And also later, it's pop-stab DT (rear 2/3 of horizontal tail popped up 90 degrees) activated to make it descend belly-flop style rather than risk gliding away.
