Inital repro app
We have an app using WKURLSchemeHandler to run a custom scheme and CORS requests seem to be broken in the latest iOS 15 Developer beta.
I have built a small reproduction app using Apache Cordova. Cordova uses WKWebView and WKURLSchemeHandler to open a local HTML file on the origin myscheme://myapp. The test button fires a request that should allow CORS request from all origins. Something like this used to work with iOS 14.
This app can be tested with Cordovas CLI or just start the Xcode project in the platforms folder.
This is just my inital observation. I will investigate further.
Thanks for reporting this.
I verified this was fixed by r278737

This issue has been fixed and release with iOS 15 Developer beta 2.
Thank you very much.
Glad to hear it
Looks like the latest Developer Beta 2 (19A5281j) brought this issue back. I got CORS issues again.
