Cross-Origin requests not working on iOS 15 beta with WKURLSchemeHandler

Summary Cross-Origin requests not working on iOS 15 beta with WKURLSchemeHandler

Created attachment 430841 [details] 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.

Looks like the latest Developer Beta 2 (19A5281j) brought this issue back. I got CORS issues again.
