ion-select component of Ionic 3 not working in IOS 9

We have developed one application using Ionic 3. We have used ion-select component at multiple places. In android & IOS version > 10, everything is working fine as expected.

But In IOS 9, ion-select component breaks. It shows blank options when tapping on ion-select.

<ion-item>
   <ion-label>Gender</ion-label>
   <ion-select>
     <ion-option value="f">Female</ion-option>
     <ion-option value="m">Male</ion-option>
   </ion-select>
</ion-item>

Solution

I was able to resolve the issue by downgrading the app-scripts version to 2.1.4 from 3.0.1.

I also had to add dev dependency tsc-wrapped to resolve some ts lint issues.

"devDependencies": {
    "@angular/tsc-wrapped": "^4.4.6",
    "@ionic/app-scripts": "2.1.4",
    "typescript": "2.3.4"
},

After changing my configuration to above, the webpack process duration came down to 3-4 minutes from 35 minutes.
