The Xcode 26.0.1 image is now available to be used in CircleCI pipelines on the M4 Pro resource classes.
Please see the full manifest for information about the software included with this image release.
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 - Device IDs are inconsistently changing across VMs in Xcode 26. This is an OS-level issue that can affect builds relying on consistent device identifiers. We’ve opened a support ticket with Apple and encourage affected users to do the same to help prioritize a fix.
