This week are joined by Greg Heo as we wade into RxSwift. We follow up on upgrading to 64-bit apps. We discuss the possibility of an OLED screen coming to the 8th iPhone model. Greg brings up the preferred software languages of weekend developers. We discuss where to define a notification? We watch Greg dance around as we quiz him on RxSwift*.
