  The trans-Planckian censorship conjecture implies that single-field models of
inflation require an extreme fine-tuning of the initial conditions due to the
very low-scale of inflation. In this work, we show how a quantum cosmological
proposal -- namely the tunneling wavefunction -- naturally provides the
necessary initial conditions without requiring such fine-tunings. More
generally, we show how the tunneling wavefunction can provide suitable initial
conditions for hilltop inflation models, the latter being typically preferred
by the swampland constraints.
