  We argue that, in the presence of time-dependent fluxes and quantum
corrections, four-dimensional de Sitter solutions should appear in the type IIB
string landscape and not in the swampland. Our construction considers generic
choices of local and non-local quantum terms and satisfies the no-go and the
swampland criteria, the latter being recently upgraded using the
trans-Planckian cosmic censorship. Interestingly, both time-independent Newton
constant and moduli stabilization may be achieved in such backgrounds even in
the presence of time-dependent fluxes and internal spaces. However, once the
time-dependence is switched off, any four-dimensional solution with de Sitter
isometries appears to have no simple effective field theory descriptions and is
back in the swampland.
