I don't want to start a new post unnecessarily, so I try here first.As you saw I have been using SwiftyJSON because they did it in the course. Also, it should be easier, but I'm not sure.Trying to follow your example, I tried this:for item in json["Trip"][0]["LegList"]["Leg"][0]["Product"].arrayValue { print(item["operator"].stringValue) }Here I try to print the value, but what I really want to do is sort out some values.So if operator is "SJ" then it should not show, but "Öresundståg" should.I don't get any errors, but nothing shows.I've read something about encodeble that's is built in. So even though you aren't use to SwiftyJSON, do you have any suggestion?It doesn't have to be SwiftyJSON.Or is there a better way to sort out values in JSON?

Ok, I'll check it out, thanks!

That seemed to work, thanks!

No, I don’t have people or firstname. That’s in the example JSON-string. So by translate I mean how to go through my JSON response in similar way.So what I want to do is parse through my response. It’s train-travels.I would like to say pick out say three trips with start and endpoint. Exactly how to do this I can figure out but would like to see how to pick out something like every station in a trip.

It worked!Thank you both!I'm sorry that I couldn't mark both as correct answers.Clearly I have to learn more about the basics.One question: Could I have made this connection completely in code?Question two: I want to display two values in one cell. The staition from the API on the left and the time on the right.Without explaining everything, could you give me a hint to the right solution?

Not sure. I connected the outlet to source and delegate.If this was working I'm not sure.How can I check this?

Yes, it is at the linetableView.delegate = self That the error fist occurs. But I can show a value set in func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { But not the value from the model.So I can docell.textLabel?.text = "test" But notcell.textLabel?.text = self.weatherDataModel.city But I know that the value is set in functionupdateWeatherData

So this is what I get after trying the suggestions from OOPer.Thread 1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional valueI think I somewhat understand Optionals but not entirely.It does suggest I guess that the object in tableView is empty. I don't understand why since.it's set in updateWeatherData.I have already connected to delegate and source in storyboard if that matters.

Thanks! I will try your suggestions when I am at my computer again. I am kind of a beginner and haven’t fully graspt everything. My approach is to make my own app while learning.

Hi! I really appreciate your help.I am trying to post in one file but keep getting the message "being moderated"Thinking that the links are the problem I removed som of the link for weather_URL and TRAIN_URL.Weather_URL are from the course I'm following and TRAIN_URL are my own testing.If the file is approved I have tried to anwer your question.The removal of the links didn't seem to help, and you need the links anyway. Adding space didn't seem to help-If you doesn't have a solution I just have to wait until it is approved.

Well, I had trouble to post. I'll try again.1. I think you missed some which is easy because of the way I posted. I probably missed the end of class.2. The const I left out are the URL for the JSON-call. I try to leave the in using your proposed method. I leave some out that I only used for testing.3. Yes, I'm sure I get there. In updateUIWithWeatherData() print out the value in a label, and that works.4. I think I had that but as I said easy to miss. Placed the two functions needed for TableView last in the file.Thank you for showing a way to easier show the code.<//// ViewController.swift// WeatherApp//// Created by Angela Yu on 23/08/2015.// Copyright (c) 2015 London App Brewery.
