How do I turn the fracture into real separate objects?
Apply the layer from the modifier stack, then in Edit Mode select all and use Mesh ▸ Separate ▸ By Loose Parts. Tested on a 7-island fracture: applying keeps the island attribute on the real mesh, and separating produces exactly 7 objects.
Can I use it for a rigid body simulation?
Not directly — a simulation needs real objects, so apply and separate first as above. Everything before that step stays editable.
