Trying to run my existing app on iOS (and iPadOS) 26 b6 shows only the splash screen after which app will not run. App runs as normal when loaded from Xcode-beta 26. Anyone else seeing this issue or have an idea how to load the app normally?
No advice, but only to say my app is working on the latest Beta.
Use safari preview and inspect the app. make sure you have proper CSP (Content Security Policy) in your index.html. in config, update allow-intent, allow-navigation properly. check for associated domains in the Xcode. one of these fix will help you to get your app work properly.
I’ve seen a few reports of this happening since the iOS 26 update. It looks like there might be a slight change in how WebKit handles the safe-area-inset or a new CSP restriction. One thing that helped me with a similar white-screen issue was making sure the viewport-fit=cover meta tag was correctly set and double-checking that the Cordova/Capacitor iOS engine is fully up to date for the new SDK.
