Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v7.x

Current Behavior

In a blank angular ionic project I tested the ion-picker in modal as described here: https://ionicframework.com/docs/api/picker#picker-in-modal

The ionChange event of the ion-picker-column (see https://ionicframework.com/docs/api/picker-column#events) works fine ONLY on android devices when the value change.
In iOS nothing is fired.

Expected Behavior

Same behavior as Android

Steps to Reproduce

1. create a blank angular ionic project
2. Insert code as the documentation in the home.page.html,home.poge.ts and home.page.scss files: https://ionicframework.com/docs/api/picker#picker-in-modal
3. To check the bug add in home.page.ts one line to the onIonChange function:

  onIonChange(event: CustomEvent) {
    console.log("onIonChange fired!", event.detail.value) // ADD THIS LINE
    this.currentValue = event.detail.value;  
  }

4. Try on an Android device: you see in the console the ionChange event fired when value change
5. Try on an iOS device: nothing is fired when value change

Hello @losciur, I am not able to reproduce.

Please confirm that you have your Safari devtools to show all logs, not just errors:

Hi, thanks for the quick answer.
After new tests I have to specify better.
My issue was generated trying the picker on a phisical iPad (fifth generation - iPadOS 16.7.5).
In that device, while I'm moving along the picker column values, or when I stop on a specific value, the (ionChange) doesn't fire.
But now, I found out that if after moving along the picker column values and stop on a specific value, I CLICK on the specific value, THEN the (ionChange) fires!

Other tests: if I use the simulator with more recent device (iOS 17), the (ionChange) correctly fire when I stop on a specific value (I don't need to click on it).

On Android: the (ionChange) fired when I stop on a specific value (no click needed)

I tested the problem in more recent models, and I found out that the bug is only in that old iPad (fifth generation - iPadOS 16.7.5).
I think it is possible to close the issue.
Thanks
