Description

Description

After upgrading to Xcode 26.4.1, a NativeScript Angular app crashes during startup on a physical iPhone when launched from Xcode.

The crash happens as soon as the app is launched and appears to come from NativeScript core/iOS runtime startup as per the error.

Environment

  • NativeScript CLI: 9.0.6

  • @nativescript/core: 9.0.0 // tried with 8.9.9 as well

  • @nativescript/ios: 9.0.3 // tried multiple versions like 8.9.5, 9.0.0, 9.0.1, 9.0.3, 9.0.4-next.2026-04-14-24422917278

  • @nativescript/angular: 17.1.1

  • Node: v24.7.0

  • ng: v20.3.1

  • npm: 11.5.1

  • Xcode: 26.4.1

  • Device: iPhone 15

  • Device iOS: 26.4.2 // also tried on 18.3.2

  • ns doctor Summary:

Error Information

NativeScript encountered a fatal error:
Error calling module function
Error calling module function
ReferenceError: UIContentSizeCategoryExtraSmall is not defined

Additional Investigation

I tried to implement the steps provided in the Issue #11135. I patched @nativescript/core/accessibility/font-scale.ios.js and vendor.js locally to remove direct UIContentSizeCategoryExtraSmall references and then the error falled back to UIContentSizeCategorySmall reference. I removed all UIContentSizeCategory... references and another error was thrown
Original error: Error calling module function ReferenceError: UIApplicationDidFinishLaunchingNotification is not defined Original stack trace: ReferenceError: UIApplicationDidFinishLaunchingNotification is not defined at new iOSApplication at app/vendor.js

After this I tried to run a basic template app created by running ns create my-app --template @nativescript/template-tab-navigation-ng to check if basic apps runs without an error but no luck, got the same errors and I am stuck.

Reproduction steps
  • Create a new basic template project
  • Open App in Xcode 26.4.1
  • Run the App
  • App crashes at runtime

Research direction

Start with @nativescript/core/accessibility/font-scale.ios.js and the startup path shown in the stack trace, then reproduce the crash with a basic template app in Xcode 26.4.1. Check whether the same missing runtime symbols occur without the reported application dependencies; done means the template app launches without the reported ReferenceErrors.
