This is programmer error; code should only request extension points that are defined by itself or its dependencies.
xcodebuild: error: Could not resolve package dependencies:
  Dependencies could not be resolved because root depends on 'rxswift' 6.0.0..<7.0.0 and root depends on 'rxexpect' 2.0.0..<3.0.0.
'rxexpect' >= 2.0.0 practically depends on 'rxswift' 5.0.0..<6.0.0 because no versions of 'rxexpect' match the requirement 2.0.1..<3.0.0 and 'rxexpect' 2.0.0 depends on 'rxswift' 5.0.0..<6.0.0.
