在Swift5中創建和撰寫子目錄時出現問題-有解無憂

我在嘗試將文本檔案寫入我的 Documents 檔案夾的子目錄時遇到問題。

我的代碼如下：

 @objc func makeFileButtonTapped() {
        print(#function)
        
        let tempName = "test"
        
    var tempRecurrance: String = ""
          
          switch recurrentInt {
          case 0:
              tempRecurrance = "Never"
              
          case 1:
              tempRecurrance = "Sometimes"
              
          case 2:
              tempRecurrance = "Often"
              
          default:
               tempRecurrance = "Unknown"
          }
          
          
          fileName = tempName   ".txt"
          
          let tempTitle: String = "\n\Title: "   titleString   "\n\n"
          let tempDate: String = "Date: "   dateString   "\n\n"
          let tempRecurring: String = "Recurs: "   tempRecurrance   "\n\n\n\n"
        
          
          myDocument = ""
          myDocument.append(tempTitle)
          myDocument.append(tempDate)
          myDocument.append(tempRecurring)
        
    
        saveToDirectory()
    }



func saveToDirectory(){
     print(#function)
        
        let fileManager = FileManager.default
       
        //  Create subdirectory
        do {
            
        let directoryURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first!
         let myAppDirectoryURL = directoryURL.appendingPathComponent("MySubDirectory")
        
        
        if !fileManager.fileExists(atPath: myAppDirectoryURL.path) {
            try fileManager.createDirectory(at: myAppDirectoryURL, withIntermediateDirectories: true, attributes: nil)
            print("New directory created.")
        
            //print("dictionary already exists.")
    }
        //  Create document
         let documentURL = myAppDirectoryURL.appendingPathComponent (fileName)
            
            try myDocument.write(to: documentURL, atomically: false, encoding: .utf8)

            print("documentURL =", documentURL.path)
        } catch {
            print(error)
        }
        
    }

我收到一條控制臺訊息，該目錄{Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}.

uj5u.com熱心網友回復：

取消檢查檔案是否已經存在，if !fileManager.fileExists(atPath: myAppDirectoryURL.path)因為createDirectory如果在您withIntermediateDirectories設定為真時目錄已經存在，呼叫將不會產生錯誤。

您使用了一些不屬于問題的屬性，因此為了完整性，這是我對您的函式的測驗版本

func saveToDirectory(_ fileName: String, text: String) {
    let fileManager = FileManager.default

    do {
        let directoryURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first!
        let myAppDirectoryURL = directoryURL.appendingPathComponent("MySubDirectory")
        try fileManager.createDirectory(at: myAppDirectoryURL, withIntermediateDirectories: true, attributes: nil)

        let documentURL = myAppDirectoryURL.appendingPathComponent (fileName)
        try text.write(to: documentURL, atomically: true, encoding: .utf8)
    } catch {
        print(error)
    }
}
