I'm not sure that's the same issue, we need to know what the actual errors are. AFAIK current Safari should support WebGL 2.

Webpage exported keep reloading, and safari reported a loading error.

Can you post the text of the errors you receive?

Safari try to load the page, and the loading progress bar seems to be loading normally, but finally the page is forced reloaded and display an error, said:

Could you get logs from Safari's Web Inspector? Not familiar with it myself but it seems it needs to be set up on a Mac to debug the iOS Safari from macOS Safari: https://appletoolbox.com/use-web-inspector-debug-mobile-safari/

Hi i exported with debug mode, the errors in console can be found:

It seems that the game script was loaded, because i can see my debug output is printed in console.

You seem to be using the JavaScript<->Godot interface, and there seem to be errors in your code:

ERROR: No interface 'game' registered
ERROR: No interface 'eventFn' registered

Those errors happen when JavaScript::get_inferface function cannot find the JavaScript object which you are requesting it to get.

• Does the project work on desktop browsers?
• Can you provide a minimal reproduction project?
• If not, can you at least provide a link where we can check the exported game?

There isn't much more we can do otherwise with the current information as this seem to be a problem with your JavaScript code but we have no way to verify it.

Hi, the project worked fine on desktop browsers, iOS 14/15 browsers and Android browsers. Just Not good on iOS 16 safari.
Even I create a fresh new project , it is the same issue.

Could you get logs from Safari's Web Inspector of the fresh new project?

Hi, there is no special error log for the fresh new project, but it crashed always:

And this is the simple demo project (create a fresh new project, add a simple button control , then export to html5):

According to this tweet, this might be due to a regression in iOS 16 beta 3 which has been fixed in beta 4: https://bugs.webkit.org/show_bug.cgi?id=242294

It seems like it was just released, please upgrade and let us know if that solves the crash.

[michaldev]

Problem solved. I've tested on iOS 16 beta 4.

[nne998]

Yeah！It's fixed!!
