Ah, sorry, that’s for ionic wkwebview plugin, in Apache wkwebview plugin the preference is <preference name="Allow3DTouchLinkPreview" value="true" />, but true is the default value.

If you are using a different wkwebview plugin or UIWebView might be a different preference or not configurable.

According to the link it’s been fixed by Apple already, but not released yet, not sure in which iOS version will be included.

Thanks and that’s the case! I’m using Apache wkwebview plugin, developers who encountered this problem, set two preferences in Cordova config.xml, and disable ‘dragstart’ event on elements in javascript, text selection works fine and 3D touch gesture is disabled as usual in iOS 13.4 (along with iPadOS 13.4):

config.xml :

<preference name="Suppresses3DTouchGesture" value="true" />
<preference name="Allow3DTouchLinkPreview" value="true" />

your app.js :

$$('body').on('dragstart', 'a', function (e) {
  e.preventDefault();
});
