Dependencies could not be resolved because root depends on 'SwiftSemantics' 0.3.2..<1.0.0.
'SwiftSemantics' >= 0.3.2 cannot be used because no versions of 'SwiftSemantics' match the requirement 0.3.3..<1.0.0 and package 'swiftsemantics' is required using a stable-version but 'swiftsemantics' depends on an unstable-version package 'swift-syntax'.

Has anyone encountered this problem ?
Thanks
