Apple's App Store Connect will finally see proper crash symbolication for .NET iOS apps after macios shipped a fix that embeds symbol files directly in the .ipa.

In brief

dotnet/macios now embeds app symbols in .ipa files via IpaIncludeSymbols. Crash logs become readable. Only took forever to make this straightforward.
Macios linker can trim ProtocolMember attributes when trimmable-static mode's on. Smaller binaries, same behavior. PrepareAssemblies handles the prep work.
MSBuild synced Arcade dependencies. Mostly infrastructure, but keeps the build toolchain in sync with dotnet platform updates.
ASP.NET Core hardens wildcard route matching for empty segments. Edge case that probably bit someone in prod before the fix landed.

The macios team landed a critical improvement [1] that addresses a years-old pain point: uploaded apps now include the `Symbols` directory Apple's tools expect, meaning crash reports will actually symbolicate instead of showing as missing symbols. This ships alongside a linker optimization [2] that trims ProtocolMember attributes when using the trimmable static registrar, letting the trimmer remove types only referenced in optional protocol members. Documentation improvements [3] for AppKit's DoubleClick events and NSEdgeInsets landed from Copilot. On the msbuild side, the main branch pulled the latest arcade dependencies [4] and nuget.client updates [5], with GitHub Actions setup tools bumped to v0.82.13 [6] [7]. ASP.NET Core hardened wildcard matching to handle empty segments safely [8]. The skills team cut a nightly build of SkillValidator from main [9]. Msbuild also expanded -mt VMR validation to run three times weekly [10] to catch source-build issues earlier.
