WebView Loading Issue iOS 18.1

Since iOS 18.1 launched as a beta, we've been getting reports from end users on iPhone 15 Pro and iPhone 15 Pro Max specifically. They're reporting that our WebView is unable to load our local HTML content. I'm curious if anyone else has had their app or users run into this issue?

So far I've tried installing the most recent XCode Beta 16B5014f and installed an 18.1 emulator, but our app worked fine. It's also working fine on all my real devices, but we don't have a 15 Pro to test on. I'm curious if this is related to the processor on these devices and how they are intended to support Apple's new AI coming in 18.1.

We received feedback from one of our affected users that updating from whatever version of the 18.1 Beta they were on to 18.1 Beta 5 fixed the issue for them. So this was definitely something related to the iOS 18.1 beta. But I cannot for the life of me reproduce it or figure out what was negatively affecting WebViews in that version.

How are you leading the content?

I always recommend WKURLSchemeHandler.

This will allow you to load resources with greater control.

Hopefully this helps.
