Maui-IOS with Net9 and Xcode16 Debugger does not hit breakpoint

[MatEngelhardt]

Hi,

After installing the .NET 9 SDK and upgrading to Xcode 16, I'm facing an issue debugging an iOS MAUI app on a physical device. The app starts, but breakpoints are not hit, and it seems like the symbols are not loading. Debugging works perfectly on the simulator and even on an Android physical device.

Steps To Reporduce:

1. Upgrade NET9 , install MAUI workloads for NET9
2. Add Debug config for MAUI
3. Start debugging

Environment:

• MacOS: Sequoia 15.2
• IPhone: 14, iOS 18.2
• XCODE: 16.1
• VSCode: 1.96.1
• ms-dotnettools.dotnet-maui Version 1.6.16

I’m unsure how to resolve this issue. Any help or guidance would be appreciated.

Thanks and regards,
Matthias
