Read File Content Example in Swift

In this short code example we will learn how to:

  • Find a Documents directory on device in Swift
  • Read file content
  

        let fileName = "myFileName.txt"
        var filePath = ""
        
        // Fine documents directory on device
        let dirs : [String] = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.allDomainsMask, true)
       
        if dirs.count > 0 {
            let dir = dirs[0] //documents directory
            filePath = dir.appending("/" + fileName)
            print("Local path = \(filePath)")
        } else {
            print("Could not find local directory to store file")
            return
        }
        
        // Read file content. Example in Swift
        do {
            // Read file content
            let contentFromFile = try NSString(contentsOfFile: filePath, encoding: String.Encoding.utf8.rawValue)
            print(contentFromFile)
        }
        catch let error as NSError {
            print("An error took place: \(error)")
        }

You can also store string values into NSUserDefaults. Have a look at this code example to learn how to write and read values of different data types from NSUserDefaults:
