when i update my ios to 13, i can not import babylon.js,but it can work in Andriod.  
The UI framework that i used is MUI. i use “script src=”…/libs/babylon/babylon.js"\>\</script"  
“script src=”…/libs/babylon/babylon.max.js"\</script" to import babylon use “canvas id=“babylon\_canvas”\>\</canvas” in html.when i in Browser ,it shows “canvas id=“babylon\_canvas” height=“929” width=“1428” touch-action=“none” style=“touch-action: none;”\>\</canvas”  
I don’t konw where bugs happended,but it work well in Andriod.

Hello and welcome!

We are going to need more info 🙂 It works on my ios13 for all [babylonjs.com](http://babylonjs.com) demo or any playground so we will need a repro or at least the error you get on the console (you will need to debug using safari from a mac)

Hum this does not help a lot ☹  
can you repro your scene on the playground?

hello Deltakosh:  
Thanks your help! I have found the cause of the babylon 3D can’t work in IOS13.  
The cause was:IOS has two webviews: UIWebview and WKWebview. Starting with IOS 13, apple listed UIWebview as an out of date API.  
We can work well with UIWebview , but the issue came out with WKWebview, as I had posted :[Can not use babylon.js in IOS13!](https://forum.babylonjs.com/t/can-not-use-babylon-js-in-ios13/6377/5)  
It would be great help for developers who are using the babylon.js with this issue fixed!
