Since we're in a "bash patterns" thread anyway... the script it's running can do whatever, so let's extend it so it works in your case too, by asking you if it's good or not, so you can still do manual app interaction with "bisect run":

   #!/bin/bash

   if ! pod install; then
       exit 125
   fi

   Q=
   while [[ "$Q" != 'y' && "$Q" != 'n' ]]; do
       read -p 'Is this revision good? [y/n] ' Q
   done

   [[ "$Q" == 'y' ]]
