you need @ whole error message. specific message includes additional information methods missing:
type 'myviewcontroller' not conform protocol 'uitableviewdatasource' protocol requires function 'tableview(_:numberofrowsinsection:)' type '(uitableview, numberofrowsinsection: int) -> int' candidate has non-matching type '(uitableview!, numberofrowsinsection: int) -> int' so... numberofrowsinsection takes optional uitableview, , should take required uitableview (this change made between 6 , 6.1, uitableview delegate , datasource methods take required tableview , indexpath values)
