我正在尝试将 Google MLKit Translate 添加到我的 SwiftUI 项目中。我已经通过 SPM 使用 firebase，并且仅在首次启动后才出现此错误：-[FBLPromise HTTPBody]: unrecognized selector sent to instance 0x600001afa700

这是我的代码：

应用程序委托

        FirebaseApp.configure()
        ...
        let spanishRemoteTranslator = TranslateRemoteModel.translateRemoteModel(language: .spanish)
        if ModelManager.modelManager().isModelDownloaded(spanishRemoteTranslator) {
            print("Spanish Translator Downloaded")
        }else {
            print("Downloading Spanish Translator")
            
            ModelManager.modelManager().download(spanishRemoteTranslator, conditions: ModelDownloadConditions(allowsCellularAccess: true, allowsBackgroundDownloading: true))
        }
        return true
}

然后我这样称呼它：

if ModelManager.modelManager().isModelDownloaded(spanishModel) {
    Translator.translator(options: englishSpanishTranslator).translate(buis.name!) { translatedText, error in
        if error == nil {
            if let translatedText = translatedText …
