Couldn't use options property of ion-slides

I have created a new app using Ionic v4 and tried adding slides to my app but I get an error stating

Can't bind to 'options' since it isn't a known property of 'ion-slides'

The html is

<ion-content padding>
   <ion-slides [options]="slideOpts">
      <ion-slide>
         <h1>Slide 1</h1>
      </ion-slide>
      <ion-slide>
         <h1>Slide 2</h1>
      </ion-slide>
      <ion-slide>
         <h1>Slide 3</h1>
      </ion-slide>
   </ion-slides>
</ion-content>

My Ts is

import { Component,ViewChild } from '@angular/core';
import { NavController } from 'ionic-angular';
@Component({
   selector: 'page-home',
   templateUrl: 'home.html'
})
export class HomePage {

   slideOpts = {
      initialSlide: 1,
      speed: 400
   };

   constructor(public navCtrl: NavController) {
   }
}

However the same worked for me in Ionic v3. Could anyone please help me out?

Try this.. its working fine ionic 4.0.0

 import { IonSlides } from '@ionic/angular';

    @Component({
      selector: 'page-home',
      templateUrl: 'home.html'
    })
    export class HomePage {
    @ViewChild(IonSlides) slides: IonSlides;
      slideOpts = {
        initialSlide: 1,
        speed: 400
      };

      constructor(public navCtrl: NavController) {
      }
     ngOnInit() {  this.slideOpts = {
        initialSlide: 1,
        speed: 400
      };
    }
    }
