Question: here is what is happening <https://imgur.com/a/fblot>

yes i've read the article about optional 

but that textfield isn't nil or without a value as it does it
when i press enter when theres a value in the text-bar
i also tried ! and ? with same results

i tried many many things and it wont work
always the same crash

can someone explain what is the reason that textfield is hard to access

i tried 

```
var = ViewControler()

```

Answer: 
Try to use the following commands to enlarge the number of handlers that actives the watcher (listener of application changes)

`sudo sysctl fs.inotify.max_user_watches=524288`
`sudo sysctl -p --system`
The issue in port 

```
app.listen(8080);

```

try these code

```
  var http = require('http');
 //create a server object:
  http.createServer(function (req, res) {
 res.write('Hello World!'); //write a response to the client
 res.end(); //end the response
}).listen(8080); //the server object listens on port 8080

```
