DatadogNet.Profiling.Mac 3.14.0.1

DatadogNet.Mac

.NET for Mac Catalyst bindings for the native Datadog iOS SDK (dd-sdk-ios) - RUM, Logs, Trace, crash reporting and feature flags for the Mac Catalyst head of a .NET MAUI (or plain .NET for Mac Catalyst) app.

This is the Mac Catalyst sibling of DatadogNet.iOS and DatadogNet.Android, and slots under the DatadogNet cross-platform façade. The API is identical to DatadogNet.iOS - same types, same namespaces (DatadogCore, DatadogRUM, DatadogLogs, ...) - because the binding definitions are verbatim copies of that repository's and Catalyst is the same UIKit platform underneath. Code written against the iOS packages compiles against these unchanged; only the package ids differ.

Support status. Datadog lists macOS (Catalyst) 12+ as partial support: the SDK compiles and its features work, but Catalyst is not a first-class tested platform upstream. Session Replay is iOS/iPadOS-only and records nothing on Catalyst (the package still ships so shared code links). Cellular/battery-derived RUM vitals are no-ops on a Mac. Test your telemetry end-to-end before relying on it.

Packages

Versioned <dd-sdk-ios version>.<binding revision>, exactly like DatadogNet.iOS: 3.14.0.1 wraps dd-sdk-ios 3.14.0, and the fourth component advances when the bindings or packaging change while the native version stays put. The iOS and Mac revisions advance independently - match on the first three components, not all four.

There is no DatadogNet.Objc.Mac: that id exists on iOS only as a compatibility meta-package for apps upgrading from the 2.x bindings, and no Mac Catalyst 2.x ever existed.

Every package targets net8.0-maccatalyst18.0, net9.0-maccatalyst18.0 and net10.0-maccatalyst26.0, with SupportedOSPlatformVersion 15.0 (macOS 12) - the floor both the .NET 9 maccatalyst workload and Datadog's own Catalyst support statement impose.

Installing

dotnet add package DatadogNet.Core.Mac
dotnet add package DatadogNet.RUM.Mac      # and the other features you use

In a multi-headed MAUI app, guard the references by platform so each head restores its own bindings:

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'maccatalyst'">
  <PackageReference Include="DatadogNet.Core.Mac" Version="3.14.0.1" />
  <PackageReference Include="DatadogNet.RUM.Mac" Version="3.14.0.1" />
</ItemGroup>

Or skip the per-platform wiring entirely and use the DatadogNet façade, which fronts the iOS, Android and Mac Catalyst bindings behind one cross-platform API.

Usage

Identical to DatadogNet.iOS - same types, same namespaces, same convenience layer - so that README is the reference. The short version:

using DatadogCore;
using DatadogInternal;
using DatadogRUM;

var configuration = new DDConfiguration(clientToken: "<CLIENT_TOKEN>", env: "prod")
{
    Site = DDSite.Us1(),
};
DDDatadog.InitializeWithConfiguration(configuration, DDTrackingConsent.Granted());

DDRUM.EnableWith(new DDRUMConfiguration(applicationID: "<RUM_APPLICATION_ID>")
{
    UiKitViewsPredicate = new DDDefaultUIKitRUMViewsPredicate(),
    UiKitActionsPredicate = new DDDefaultUIKitRUMActionsPredicate(),
});

samples/DatadogNet.Mac.Example is a runnable MAUI Catalyst app showing RUM, Logs, Trace and crash reporting - the honest Catalyst feature set.

How this repository works

The one structural difference from DatadogNet.iOS: the native frameworks are built here, not downloaded. Datadog publishes no Mac Catalyst binaries - Datadog.xcframework.zip carries iOS device and simulator slices only, and the prebuilt OpenTelemetryApi covers every Apple platform except Catalyst - so build/BuildXcFrameworks.sh compiles dd-sdk-ios at the pinned tag for platform=macOS,variant=Mac Catalyst and assembles single-slice (ios-arm64_x86_64-maccatalyst) xcframeworks into libs/. Two project-file patches make that possible; the script documents both.

The binding definitions (ApiDefinitions.cs, StructsAndEnums.cs, Additions/) are verbatim copies from DatadogNet.iOS, refreshed by build/SyncBindingsFromiOS.sh. Do not edit them here: fix them in the iOS repository and re-sync, so the two platforms cannot drift.

Layout

build/    BuildXcFrameworks.sh (native build), BuildNugets.sh (pack), SyncBindingsFromiOS.sh,
          merge-packages.py (grafts the net10 pass into the net9-band packages)
libs/     the Catalyst xcframeworks (built, not committed) + BUILD-INFO.txt
src/      one binding project per package + Datadog.Binding.props (everything they share)
tests/    package layout tests, run against the packed .nupkg files
samples/  MAUI Mac Catalyst example app, built against the packed packages

Building locally

./build/BuildXcFrameworks.sh   # needs Xcode; ~15 minutes, cached by DATADOG_BUILD_DIR
./build/BuildNugets.sh         # packs all eleven packages into ./artifacts
dotnet test tests/DatadogNet.Mac.PackageTests
dotnet build samples/DatadogNet.Mac.Example/DatadogNetExample.csproj -p:RuntimeIdentifier=maccatalyst-arm64

Needs the .NET 9 and .NET 10 SDKs with the maccatalyst workload in each (BuildNugets.sh packs twice and merges - no single SDK can build all three target frameworks), plus maui-maccatalyst for the sample.

Upgrading the Datadog SDK

1. Bump DatadogNativeVersion in Directory.Build.props, reset DatadogBindingRevision to 1.
2. Update DatadogOtelVersion to whatever the new tag's Cartfile.resolved pins.
3. Wait for (or produce) the matching DatadogNet.iOS release, then run ./build/SyncBindingsFromiOS.sh against it and review the diff.
4. ./build/BuildXcFrameworks.sh && ./build/BuildNugets.sh && dotnet test tests/DatadogNet.Mac.PackageTests
5. Update the README table and docs/release-notes/.

Releasing

Push a tag v<version>, e.g. v3.14.0.1. The release workflow builds the xcframeworks, packs, validates, publishes to nuget.org via trusted publishing, and creates a GitHub release; a curated docs/release-notes/<version>.md replaces the generated commit list when present. Pull requests publish -beta.<pr>.<run> prereleases the same way.

Licence

The binding code in this repository is MIT. The native binaries the packages embed are built from Datadog's Apache-2.0 sources (dd-sdk-ios, KSCrash, opentelemetry-swift); every package carries both texts under licenses/. Not an official Datadog product.
