splitPane unknown

I am trying to use the new component splitPane. I follow this steps from this link

> https://chrisgriffith.wordpress.com/2017/02/25/ionic-split-panel-component/

but i got some issues with that
when i add the tag, i get this error:
" ion-split-panel is not a known element."

I’am adding already this line to tell angular bring me up the ionic elements

imports: [

to my NgModule but this not remedy my problem
what do you suggest ?

There was a slight name change to the component from the beta to final release. The correct name is <ion-split-pane> not <ion-split-panel>
