I am trying to write data that is inputted by a user via UITextField
to a text file. I am successfully able to do this by the code I have written below. However, when I tried to save more data it will replace the existing data in the textfile with the new data that is being saved. for example, if I save the string 'hello world' and then save another string saying 'bye'. I will only see the string 'bye' in the textfile. Is there a way I can modify my code so I can see 'hello world' on one line of the textile and 'bye' on another.
@IBAction func btnclicked(_ sender: Any) {
self.savedata(value: answer.text!)
}
func savedata (value: String){
let fileName = "Test"
let DocumentDirURL = try! FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
let fileURL = DocumentDirURL.appendingPathComponent(fileName).appendingPathExtension("txt")
print("FilePath: \(fileURL.path)")
let writeString = NSString(string: answer.text!)
do {
// Write to the file
try writeString.write(to: fileURL, atomically: true, encoding: String.Encoding.utf8.rawValue)
} catch let error as NSError {
print("Failed writing to URL: \(fileURL), Error: " + error.localizedDescription)
}
}
