Known Issues:
- iOS 26 simulators sporadically freeze during boot and may fail to start. We recommend pre-booting simulators and, if they don’t start within 60 seconds, terminate them and restart them.
- Metal Toolchain is currently non-functional. A workaround is available by running the following commands before use:
xcodebuild -downloadComponent metalToolchain -exportPath /tmp/MetalExport/ sed -i '' -e 's/17A5295f/17A5241e/g' /tmp/MetalExport/MetalToolchain-17A5295f.exportedBundle/ExportMetadata.plist xcodebuild -importComponent metalToolchain -importPath /tmp/MetalExport/MetalToolchain-17A5295f.exportedBundle
