  This paper presents a conditional convergence result of solutions to the
Allen--Cahn equation with arbitrary potentials to a De Giorgi type $
\mathrm{BV} $-solution to multiphase mean curvature flow. Moreover we show that
De Giorgi type $\mathrm{BV} $-solutions are De Giorgi type varifold solutions,
and thus our solution is unique in a weak-strong sense.
