When running top-level async code in Swift Playgrounds, the LLDB RPC server crashes. For example, when running the following code from Concurrency section of The Swift Programming Language book: func fetchUserID(from server: String) async -> Int { if server == primary { return 97 } return 501 } let userIDs = await withTaskGroup(of: Int.self) { group in for server in [primary, secondary, development] { group.addTask { return await fetchUserID(from: server) } } var results: [Int] = [] for await result in group { results.append(result) } return results } print(userIDs) Xcode reports that the LLDB RPC server has crashed. The Swift Playground app reports “There was a problem running this playground.” However, in the case of the Swift Playground app, results are populated as expected. For example, the console shows “[97, 501, 501]”. Xcode does not print any results in the console. Tested with Xcode 26.4 (17E192) and Swift Playground Version 4.7 (2088). Wrapping the as
