  We study the interplay of the trans-Planckian censorship conjecture (TCC) and
the swampland distance conjecture (SDC) in the context of multifield dark
energy in a curved field space. In this scenario, the phase of accelerated
expansion is realized as non-geodesic motion in a highly-curved field space,
reminiscent of models developed in the context of inflation. The model features
a stable attractor solution with near constant equation of state $w\simeq -1$,
and predicts that the current era of accelerated expansion is eternal. The
latter implies an eventual conflict with the TCC, which holds that the duration
of any epoch of cosmic acceleration is bounded by the requirement that the
large-scale observable universe is blind to Planck-scale early universe
physics. This tension can be resolved by an interplay with the distance
conjecture: for suitable parameter values, the apparent violation of the TCC
occurs well after the fields have traversed a Planckian distance. The SDC then
predicts a breakdown of the effective field theory (EFT) before the TCC can be
violated. We derive the constraints on the model arising from the SDC+TCC and
the de Sitter conjecture. We demonstrate that the model can be consistent with
both swampland conjectures and observational data from Planck 2018 and the Dark
Energy Spectroscopic Instrument.
