App error when accessing with iPhone 11 but not iPhone 15

Anvil Q&A
1

Hey all,

I’ve had errors lately when trying to access my app via webkit browsers on certain iPhones (duckduckgo browser and Safari both had the issue). Oddly, an iPhone 15 with the exact same Safari version and OS version does not throw an error. I also don’t see any issues in the Anvil errors logs. However on iPhone 11 the app does not load.

Both are on iOS 17.3.1, JavaScript and cookies enabled, WebKit 605.1.15 (KHTML, like Gecko) Version/17.3.1 Mobile/15E148 Safari/604.1

you have some incorrect syntax in your native libraries

export defatult ...
isn’t valid javascript in the browser unless it’s inside a javascript module

Changing that might be enough to fix the issue
if that doesn’t work, then it would probably be worth creating a clone link that demonstrates the issue.

Thanks

Removing the “Export default…” did not fix it. I will try to create a clone link shortly

It seems the app is working fine in iPhone 11 and DuckDuckGo browser / Safari.

Any updates what the issue was?

We haven’t done any investigation beyond the post above as we were waiting to see a clone link.
