Swampland conjecture has been recently proposed to connect early time
cosmological models with the string landscape, and then to understand if
related scalar fields and potentials can come from some fundamental theory in
the high energy regime. In this paper, we discuss swampland criteria for $f(R)$
gravity considering models where duality symmetry is present. In this
perspective, specific $f(R)$ models can naturally belong to the string
landscape. In particular, it is possible to show that duality is a Noether
symmetry emerging from dynamics. The selected $f(R)$ models, satisfying the
swampland conjecture, are consistent, in principle, with both early and
late-time cosmological behaviors.
