when modally presenting, or pushing, interface controller can specify context parameter pass data new controller follows. // push [self pushcontrollerwithname:@"mycontroller" context:[nsdictionary dictionarywithobjectsandkeys:someobject, @"somekey", ..., nil]]; // modal [self presentcontrollerwithname:@"mycontroller" context:[nsdictionary dictionarywithobjectsandkeys:someobject, @"somekey", ..., nil]]; my question is, how can reverse? say present controller modally user pick item list , return main controller, how can item has been picked? i wrote full example uses delegation in watchkit, passing delegate instance in context, , calling delegate function modal : here full project example on github here principale classes of example : interfacecontroller.swift this main controller, there label , button on view. when press button, presentitemchooser called , present modalview (modalinterfacecontroller). pass instance of
