Xcode swift-复制捆绑包后AVAudio Player无法工作

Question

[我正在使用AVAudio播放器，目前正在收到以下错误-致命错误：展开一个可选值时意外发现nil：文件

我查看了各种解决方案，问题是所需的文件不在副本分发包资源区域中。但是文件已添加到所需的目标位置，因此不确定解决方案。

import Foundation
import Capacitor

@objc(Buckfast)
public class Buckfast: CAPPlugin {

@objc func echo(_ call: CAPPluginCall) {
    let value = call.getString("value") ?? ""
    call.success([
        "value": value
    ])

    var bombSoundEffect: AVAudioPlayer?

if let path = Bundle.main.path(forResource: "1", ofType: "wav") {
   let url = URL(fileURLWithPath: path)

   do {
       bombSoundEffect = try AVAudioPlayer(contentsOf: url)
       bombSoundEffect?.play()
   } catch {
       // couldn't load file :(
   }
}

}

}

您可以尝试像if let一样使用[]来解开包装>

if let path = Bundle.main.path(forResource: "1", ofType: "wav") { 
}
