### Describe your issue

Hello,
I attempted to build CopilotForXcode locally, but received the following error:
```
Call to method 'rebuildService' in closure requires explicit use of 'self' to make capture semantics explicit
```

My development environment is:
```
admin@Mac-mini ~ % xcodebuild -version
Xcode 14.1
Build version 14B47b

admin@Mac-mini ~ % swift --version
swift-driver version: 1.62.15 Apple Swift version 5.7.1 (swiftlang-5.7.1.135.3 clang-1400.0.29.51)
Target: arm64-apple-macosx12.0
```
The code version I am trying to build is tag 0.18.0.

Could you please provide any guidance on how to address this error?

Thank you in advance for your help.

Best regards,
