Tauri iOS Simulator Crash on Launch — Works on macOS and Dev Server

Hi all,
I'm having trouble deploying my Tauri app to the iOS simulator. The app builds successfully, but crashes immediately upon opening in the simulator.

This crash does not occur when:

• Running the dev server (tauri dev)
• Running the app as a native macOS build

Additionally, SpringBoard crashes on simulator startup, which may or may not be related.

What I’ve tried:

• Verified the app runs fine on macOS
• Cleaned and rebuilt the project
• Tested on multiple simulators (e.g., iPhone 15, iOS 17.x)

Environment:

• macOS 14.6
• Xcode 16.0
• Tauri CLI 10.9.2
• Cargo 1.86.0
• VS Code

Console output:

    com.farmhand-scouter.app: 34707
    Info Watching ~/src-tauri for changes...
    getpwuid_r did not find a match for uid 501
