Connection is established using: let connection = NWConnection(to: .unix(path: "/var/run/usbmuxd"), using: NWParameters.applicationService) connection.stateUpdateHandler = { [weak self] in self?.onConnectionState($0) } connection.start(queue: Self.dispatchQueue) Where Self.dispatchQueue is a serial DispatchQueue with maximum 1 thread, .background QOS

For me it's the restorecount.plist error only. 100% SwiftUI app.
