Description

After updating my macOS to Tahoe 26.0 and consequently Xcode to 26.0, my iOS builds started crashing when using the native iOS back swipe gesture.

When I navigate between pages in my NativeScript app and go back using the system gesture (swipe from the left edge), the app crashes after a few quick back-and-forth navigations.

The crash seems to happen more consistently if I swipe quickly between pages multiple times (e.g. go A → B → A → B → A → C using the native back gesture).

Environment

• macOS: 26.0 (Tahoe)
• Xcode: 26.0
• NativeScript CLI: 8.8.3
• Runtime: @nativescript/ios 8.9.4
• Runtime: @nativescript/core 8.9.9
• Framework: Angular 18.0.3

Steps to reproduce

1. Run the app on iOS (device or simulator).
2. Navigate through a few pages (A → B → C, etc.).
3. Swipe back using the native iOS back gesture several times quickly.
4. After 2-3 rapid gestures, the app crashes.

Expected behavior

The app should handle native back navigation gracefully without crashing.

Actual behavior

After a few rapid back gestures, the app crashes with Cannot read properties of null (reading 'view').

Notes

• This issue only appeared after updating to macOS Tahoe 26.0 / Xcode 26.0.
• The same app worked fine on the previous macOS/Xcode combination.
