Mac Catalyst Release publish fails with ArcGIS Maps SDK for .NET MAUI 200.8.1 (Info.plist merge error)

Question

Hi,

I can reproduce a Mac Catalyst Release publish failure in a clean .NET MAUI project when adding Esri.ArcGISRuntime.Maui 200.8.1.

A standard MAUI template publishes successfully for Mac Catalyst. However, after adding the ArcGIS package and initializing it with .UseArcGISRuntime(), the architecture-specific builds succeed but the final universal app merge fails.

Environment

* ArcGIS Maps SDK for .NET MAUI: 200.8.1

* Target: net10.0-maccatalyst

* Machine: Apple Silicon MacBook Pro

* Build command:

dotnet publish -f net10.0-maccatalyst -c Release

Steps to reproduce

Create a new MAUI project

dotnet new maui -n MauiApp1
cd MauiApp1

Publish Mac Catalyst Release

dotnet publish -f net10.0-maccatalyst -c Release

This succeeds.

Add ArcGIS NuGet package

Initialize ArcGIS in MauiProgram.cs

builder.UseArcGISRuntime();

Publish again

dotnet publish -f net10.0-maccatalyst -c Release

Result

Both architecture builds succeed:

* maccatalyst-x64

* maccatalyst-arm64

But the final universal bundle merge fails with:

Unable to merge the file
Contents/Frameworks/RuntimeCoreNet.framework/Versions/A/Resources/Info.plist
it's different between the input app bundles.

Investigation

Comparing the generated files shows different CFBundleIdentifier values inside RuntimeCoreNet.framework:

arm64

com.esri.ArcGISXamarinArm64

x64

com.esri.ArcGISXamarinSimx64

This difference appears to cause the universal Mac Catalyst bundle merge to fail.

Workaround

Publishing a single architecture works:

dotnet publish -f net10.0-maccatalyst -c Release -p:RuntimeIdentifier=maccatalyst-arm64

Question

Is this a known issue with the ArcGIS Maps SDK for .NET MAUI 200.8.1 packaging for Mac Catalyst?

Thanks.

The Mac Catalyst universal publish issue has been resolved. If you upgrade the package reference to ArcGIS Maps SDK for .NET MAUI 300.0, the workaround is no longer needed. You should be able to publish without restricting to a single architecture:

dotnet publish -f net10.0-maccatalyst -c Release

This is by design and not specific to 200.8.1 . It applies all versions of the ArcGIS Maps SDK for .NET MAUI on Mac Catalyst. You will need to specify a single architecture at publish time, as you already found.
