Border-radius not working on IOS

Ionic Framework Ionic Angular

Hi. I’m doing an app in IOS and Android.
For some reason when I’m using border-radius it’s working in the android, but not in the IOS.
Can someone help me out?

This is the html:

<ion-list style="border-radius: 15px; margin-bottom: 10px">
        <ion-item>
          <ion-label fixed color="primary">Label 1</ion-label>
          <ion-input
            type="text"
            [(ngModel)]="labelOne"
            required
          ></ion-input>
        </ion-item>

        <ion-item>
          <ion-label color="primary" fixed>Label2</ion-label>
          <ion-input
            type="text"
            [(ngModel)]="labelTwo"
            required
          ></ion-input>
        </ion-item>


        <ion-item>
          <ion-label color="primary" fixed>Label3</ion-label>
          <ion-input
            type="text"
            [(ngModel)]="labelThree"
            required
          ></ion-input>
        </ion-item>
      </ion-list>

Thanks in advance
