SWR aka Standing Wave Ratio is calculated for the reflection due to an impedance mismatch along the transmission-line. This is more relevant to Tx because of the power levels involved.

Ergo, SWR calculation will only be applicable to a receiver insofar as a 1:1 (or as close as may be achieved!) indicates the signal incident on the receiver is not reflected back from the receiver.

The resonant frequency/band of the antenna is the ease with which that antenna will intercept signals for that frequency/band from the air.

Best scenario is when the SWR is 1:1, and the receiver is tuned to the resonant frequency of the antenna itself.
