It seems that our CI jobs are using XCode 16.4 and the latest version of XCode, 26.4, bumped clang to version 21 which adds some new warnings (`-Wimplicit-int-enum-cast` and `-Wimplicit-void-ptr-cast`). These warnings are picked locally as build errors. This fixes the local build. Build command used locally: ``` ./build.sh -arch arm64 -os iossimulator -s clr+clr.runtime+libs+packs+libs.tests -c Release /p:UseMonoRuntime=false /p:UseNativeAOTRuntime=false /p:EnableAdditionalTimezoneChecks=true /p:EnableAggressiveTrimming=true ```
