ios - Did UICollectionView change protocol along with Xcode 7, swift 2.0? -

this question has answer here:

• redundant conformance error message swift 2 2 answers

mycollectionviewcontroller subclasses uicollectionviewcontroller, uicollectionviewdelegate , uicollectionviewdatasource. worked fine before switched swift 2.0. following error: "redundant conformance of mycollectionviewcontroller protocol uicollectionviewdatasource".

i checked official uicollectionview class reference still states have use both delegate , data source. if don't subclass delegate , data source seems app works. there in particular should note? or maybe updated official documentation?

uicollectionviewcontroller defines conforming uicollectionviewdelegate , datasource.

by declaring conformance again making redundant declaration.

if read error message it's telling you.

just delete delegate , datasource conformance subclass.
