For reading and writing you should use a location that is writeable, for example documents directory. The following code shows how to read and write a simple string. You can test it on a playground.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | let file = "file.txt" //this is the file. we will write to and read from it let text = "some text" //just a text if let dir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first { let fileURL = dir.appendingPathComponent(file) //writing do { try text.write(to: fileURL, atomically: false, encoding: .utf8) } catch {/* error handling here */} //reading do { let text2 = try String(contentsOf: fileURL, encoding: .utf8) } catch {/* error handling here */} } |
