Img does not load dynamically ios

Ionic Framework ionic-v3
1

Hello,

on IOS I have the problem that the images will not be shown, but on the web browser it works.
The list items are loaded from backend…
The getImg function returns a svg.

  <ion-list [virtualScroll]="cars">
    <ion-item *virtualItem="let car">
      <ion-img item-left [src]="getImg(car)"></ion-img>
      <h2><strong>{{ car.name}} </strong></h2>
      <i> {{ 'TYPE' | translate }}: </i> {{ car.type}}<br>
      <i> {{ 'COLOR' | translate }}: </i> {{ car.color}}<br>
    </ion-item>
  </ion-list>
