ios – Stockfish NNUE file not loading in ChessKitEngine

I’m utilizing ChessKitEngine to combine Stockfish into my iOS app. I’ve added the nn-1111cefa1111.nnue file to my challenge’s root folder and included it within the targets. The file was downloaded from the official Stockfish web site, and I’ve not renamed it.

Difficulty

Regardless of how I specify the NNUE file (filename, full path, escaped areas, and so on.), the engine all the time fails to load it and crashes.

My Code

import Basis
import ChessKitEngine

remaining class StockfishEngine {
    static let shared = StockfishEngine()
    personal let engine = Engine(sort: .stockfish)
    personal var isReady = false
    personal var pendingCompletionHandlers: [(String?) -> Void] = []

    init() {
        startEngine()
    }

    func startEngine() {
        print("Beginning engine initialization...")
        engine.loggingEnabled = true
        engine.begin {
            self.engine.ship(command: .uci)
            
            // Trying to set the NNUE file
            self.engine.ship(command: .setoption(id: "EvalFile", worth: "nn-1111cefa1111.nnue"))
            
            let threadCount = min(ProcessInfo.processInfo.processorCount - 1, 7)
            self.engine.ship(command: .setoption(id: "Threads", worth: String(threadCount)))
            self.engine.ship(command: .setoption(id: "Talent Stage", worth: "10"))
            
            self.engine.ship(command: .isready)
            
            self.engine.receiveResponse = { response in
                if "(response)".comprises("readyok") {
                    self.isReady = true
                    print("Stockfish Engine Began!")
                    self.processPendingRequests()
                    self.setupMoveResponseHandler()
                }
            }
        }
    }
}

The UCI possibility EvalFile would possibly have to specify the total path, together with the listing title, to the community file.

  ERROR: The engine can be terminated now.

What I Have Tried

• Specifying simply the filename: "nn-1111cefa1111.nnue"
• Utilizing the total path:

  let path = Bundle.essential.path(forResource: "nn-1111cefa1111", ofType: "nnue")
  self.engine.ship(command: .setoption(id: "EvalFile", worth: path ?? ""))
  

• Escaping areas within the path
• Verifying the file exists within the app bundle

Nonetheless, nothing appears to work. How can I appropriately load the NNUE file for Stockfish utilizing ChessKitEngine?
