WebGL builds crash issue on IOS browsers - Unity3D

Hello,

Hope you're all doing good. There is a persistance issue I am facing and I have tried every possible solution but still i can't get rid of the issue even on an empty project.

Bug Explanation:

• An error is shown at the top of the browser stating "This browser was reloaded because of a problem occurred"
  
• This is happening only in all IOS browsers (safari and chrome majorly)
• The error is inconsistent. Steps to produce are explained in the following heading. It seems if the HTML is heavy and involves more processing, its easier to produce the issue.
  
  Check following screenshot.
  
  

Steps to re-produced:

1. Open Safari in any IOS device
2. Go to any website (like www.google.com)
3. Navigate to my game link (http://34.236.28.152/n2y/EmptyDemoV1/)
4. Once the unity scene has fully loaded(even its just a text, it takes time to load the scene), press browser back button
5. Repeat step 3-5 remaining in the same browser session, will reproduce the bug sometimes on 5th try, sometimes on 3rd and sometimes on 7th (inconsistently occur)

Things that I have already tried:

• Optimize WebGL build as much as possible from Unity's side (compression on texture, brotli and gz compression (enabling and disabling), memory size, etc)
• Disabling cookies from html file (deleting cookies through JS)
• The only way it seems to be not producing the bug is by disabling the cookies from Safari browser settings in Iphone settings. But that is not the solution because it creates a lot other problems in general session handling on other websites.
• We have also tried stripping different code sections from the final HTML produced by Unity. Interestingly once it doesn't have the Unity scene div in it and unity related javascript, the problem doesn't occur. Has to do something with Unity webGL?

Following is the link to a sample Unity WebGL build:
http://34.236.28.152/n2y/EmptyDemoV1/

• Once Unity scene is loaded, it has nothing but a dummy screen having a single text "Hello World".

Looking forward to positive response in getting this issue fixed.

 

Schubkraft thanks a lot for the quick reply,
I'm aware of WASM export but as I was working in unity 5.5, so never got to try this feature but I will definitely try this now at this point and will also use the tool you mentioned but as I have mentioned, this is specifically an issue with iphone browsers as same game works completely fine on other platforms, I was hoping you could help me out on that specific issue If you can, not as general.
I'm ready to explore any possibility you throw at me to resolve this issue.
Thanks.

 

thank you for all your help, ill work on your advice and see if I can come up with a solution.
Thanks for your help, really appreciate it.

 

Hi It has been another 18 months, has there been any further movement to support WebGL on mobile. In particular iOS?

 

Yes currently Safari keeps compiled wasm code in memory; so reloading the page over and over again will cause a crash regardless of how "simple" your 3D scene is (at the moment Safari does not garbage collect code fast enough). However opening up the page in a new tab will give you a "fresh start" so to speak.

 

Hello,

How about now? Hows the WebGL support coming alonng?

Thanks,

Hey,

is there any way to make a stable WebGL build for Safari? Mine is crashing sometimes even during the loading process at the beginning with the same error message. My client requires a web version that is playable on mobile devices and I really need a solution for this.

Any help would be highly appreciated!

 

well, this problem still exists

 

The problem is still there

 

We can run most games on iOS safari, except for very heavy content games such as mmo, which are limited to memory

 

I am using 2021.3 LTS. I am working on a WebAR project with unity. The project works well on windows and android. But when it runs in ios safari/chrome, the browser crashes randomly. The crash happens more likely when more resources are used. For example, when I turn off the camera, the app works well. When I turn on the camera, and the output resolution is 600 x 800, the crash percentage is less than 10%. When I increase the output resolution to 900x1600, the crash percentage is about 50%. If i increase the output resolution to 1080x1920, the crash percentage is 100%. I guess it's caused by the memory limitation of ios? or a bug of ios?
