In this example you can read data from a file in your iOS device
let home = FileManager.default.homeDirectoryForCurrentUser let playgroundPath = "Documents/dev/xcode/DatePicker/c" // Get your playground URL let playgroundURL = home.appendingPathComponent(playgroundPath) let newFile = playgroundURL.appendingPathComponent("test.txt").path let fileHandle: FileHandle? = FileHandle(forReadingAtPath: newFile) if fileHandle != nil { // Read data from the file let data = fileHandle?.readDataToEndOfFile() // Close the file fileHandle?.closeFile() // data to string conversion let text = String(data: data!, encoding: String.Encoding.utf8) as String! print(text ?? "") } else { print("Ooops! Something went wrong!") }
