When executing Chapter 2 on swift playground with xcode, I get the following error message
Cannot find type 'PriorityQueue' in scope
on line (according to chapter 2.2.5 A* search)
var frontier: PriorityQueue<Node<StateType>> = PriorityQueue<Node<StateType>>(ascending: true, startingValues: [Node(state: initialState, parent: nil, cost: 0, heuristic: heuristicFn(initialState))])
Swift 5.7 and Xcode Version 13.4.1 (13F100)

Sorry. I opened the playground in a wrong way. The PriorityQueue is in the Sources when cloning the GitHub and opening the playground file.
