The effective field theory of cosmic inflation has been highly constrained by the swampland conditions recently. In brane inflation the Friedmann equation is modified to include an additional parameter λ called brane tension that modifies the slow-roll parameters such that the restrictive swampland conditions can be naturally evaded. We discuss superconformal α-attractor E-models that are consistent with distance conjecture and the further refined de Sitter conjecture. We derive an analytic formulae for n_s and r that approximates the accurate results very well. This class of models satisfies various consistency requirements and is also consistent with the Planck 2018 and BICEP2 observational constraints on n_s and r.
