Fixed build phases order

See [Xcode 10's known issues](https://developer.apple.com/documentation/xcode-release-notes/build-system-release-notes-for-xcode-10) in the release notes:

> Targets with Copy Headers build phases ordered after Compile Sources build phases may fail to build and emit a diagnostic regarding build cycles. (39880168)
>*Workaround*: Arrange any Copy Headers build phases before Compile Sources build phases.

This has been an issue for nearly 4 years, and now with Xcode 13.3 it leads to `XCBBuildService` to crash consistently.
