How a four-dimensional de Sitter solution remains outside the swampland

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