What is JSON and how do you parse JSON in Swift? This video will show you!
JSON stands for JavaScript Object Notation and it's a way to represent data in a standard way. It helps organize that data in a way that machines can "read".
Think about how a dictionary is organized alphabetically and each entry has a word followed by a definition. There's a well defined standard which makes it easy to process the info.
The JSON data format is often used in a data feed or in the returned data from an API call.
Because the data is in a standard data format, our app can "parse" out the information from the data feed or API response.
To understand how JSON is organizes data, you need these 3 concepts:
Key-Value pairs: The key is a label and the value is the actual data. Together, a key-value pair represents one piece of information.
JSON Object: This is a collection of key-value pairs together. Often the key-value pairs are related together so that the collection (JSON object) represents a bigger piece of data. For example, the JSON Object could represent a person and the collection of key-value pairs represents the attributes of the person.
Array: An array in JSON represents a list of JSON objects or other values.
For an example of JSON data, check out the video tutorial! In the video, I also show how to parse JSON in Swift using the Codable protocol.
We take the response JSON data from a real API call and then parse it in Swift!

@gauntletwielder6306 4 года назад

I had to come back and watch this again. Why? Because people who watched this came to me for help. *This is a great instructional video* However, it is only one side of the same coin. The other side of the coin... doing something practical with the JSON data outside the scope of the completion handler. Maybe presenting the data in a tableView and *not* on a background thread. And having that data available when a user selects a tableViewCell. So many people have come to me because they do not know how to continue where this video leaves off. People are looking forward to seeing Part 2 of this. Thank you.

Hello, maybe this other video will help on how to present JSON data ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Yzx7ihtCGBs.html - Francis

@gauntletwielder6306 4 года назад

CodeWithChris - Thank you Francis. However, that specific video mostly describes what an API is. Great for anyone wanting only to know what an API is. Unfortunately, that video *is not* the equivalent to a Part 2 of this video. This video needs a genuine follow up to show how to retain and use the collected JSON data *outside the scope of the completion handler* Getting the data is half the objective, processing and presenting it, is the remaining half. How many apps in the App Store use print(“...”) to display data to the user? Hint: the answer rhymes with Nero. A genuine Part 2 to this video, would be welcomed by many people.

@michaelpowers7164 4 года назад

How would you go about parsing date ranges? For example, the data goes back to 1914, but I only want to extract data from 2020. What woud be the best way to do it? example- To filter the dataset to only return records containing a specified value for incident_datetime simply add a URL parameter to your URL with incident_datetime as the key and your specified value.

@CodeWithChris 4 года назад

Hello, as long as the records are in the same format then it then be fine, you might need to ""recalculate"" or cast your date records into Date format so it will be easier to handle, i suggest searching around on google there are plenty of articles that cover ordering/filtering by date - Francis

Hey Chris! What do I do if I am working with a api that has a dictionary inside a dictionary, inside an array, etc. I know we can use the structure code, but how do we do this if it is all nested?

@CodeWithChris 4 года назад

Hello, depends on your structure, so if you have an array inside an array its somthing like a[0][0].. or if theres a dictionary inside the array then maybe a[0]["name"], or something similar, it depends on which one is first and you just add the additional step to be able to access it - Francis

@davidleda2324 3 года назад

Hi Francis! Hi Chris! It would be great if you could make a tutorial explaining how to display JSON data in SwiftUI. There's already several tutorials out there explaining this but they all use the List container to display the data. But Lists require your struct to be Identifiable, otherwise it won't work: ``` struct Todo: Codable, Identifiable { public var id: Int public var title: String public var completed: Bool } ``` In this example the response object from the API has and "id" key. But what if it didn't have one? Then you cannot make it Identifiable, and therefore you cannot pass the data to a List container. Therefore, my question is: how do you display JSON data in Content View without using the List container? Thank you!

After watching the video (numerous times) I built an Xcode project to mimic what you did in the video. I got it all working and then made a change were retrieving the JSON feed is being handled in a method within ViewController.swift. So now the only additional line in the viewDidLoad() method is this: getJSONFeed(). The method (getJSONFeed) is working fine and I'm able to put in a break and make sure that I did, indeed, retrieve the JSON data feed but I'm having trouble trying to figure out HOW to pass that data back from the method getJSONFeed() to viewDidLoad(). I think I have two problems that I need help with: 1. I have created a class property as an optional NewsFeed type: var thisNewsFeed:NewsFeed? I'm not sure if this is correct. 2. I am then trying to set this variable within the getJSONFeed() method by adding self.thisNewsFeed = newsFeed. I then placed a print(self.thisNewsFeed) in the code and it properly displays the JSON data that was retrieved. However when trying to access the thisNewsFeed back in viewDidLoad(), after the call to getJSONFeed() it's NIL. I think my problem is this: how to pass data from a closure. here is the ViewController.swift code: import UIKit class ViewController: UIViewController { // Class properties var thisNewsFeed:NewsFeed? override func viewDidLoad() { super.viewDidLoad() getJsonFeed() // peek at value of class property after the call to getJsonFeed() if thisNewsFeed != nil { print(thisNewsFeed!) } } func getJsonFeed() { // Hit the API endpoint let urlString = "newsapi.org/v2/everything?q=bitcoin&from=2020-02-12&sortBy=publishedAt&apiKey=hiding_my_api_key_for_this_posting" let url = URL(string: urlString) let session = URLSession.shared let dataTask = session.dataTask(with: url!){ ( data, response, error) in // check for errors if error == nil && data != nil { do { // Parse JSON let decoder = JSONDecoder() let newsFeed = try decoder.decode(NewsFeed.self, from: data!) // now set the class property thisNewsFeed self.thisNewsFeed = newsFeed // and display it to insure it actually contains the JSON data print(self.thisNewsFeed!) } catch { print("error in JSON Parsing") } } } // Make the API Call dataTask.resume() } } Any help would be appreciated!!!

@@CodeWithChris my question was if you have any tuts or paid courses that goes in details on UI testing, and Unit testing for UIKit ? It's so hard scavenging the web for these two topics, not enough in-depth resources. If you have any resource that can help a beginner get competent in unit or UI testing please share it with me

Hi Chris! When printing the newsFeed it just says newsFeed() in the console. Do you know what the problem could be and why it doesnt print the contents of stockData?

Hi Chris! How can I send a request or change a value in the JSON file with an action in my App?

I wrote an app that stores JSON data into UserDefaults. I wanted to add a new property to the struct. When I ran the app, the decode failed. I assume it was because I attempted to read a property that wasn't defined in the JSON. Is there an easy way to get around this? Is there a specific error code I can check for?

@CodeWithChris 3 года назад

"Hello, i don't think you can store JSON property in UserDefaults, you can probably save it as converted value (the class you made) instead, or save a local copy of the JSON file to your directory instead - Francis"

@stuartthompson1943 4 года назад

A few people have asked this perhaps you know what to do? The problem is: THEN what? I have data in a URLSession response but that's asynchronous, so my app has moved on and my data is sitting somewhere I can't access. I have a bunch of data but how do I get it back to the parent? (In Javascript I'd nest the function or use await, for example.)

@stuartthompson1943 4 года назад

Hello, you can try to make an external swift file, lets say ""globalData.swift"" and declare the variables you want to use there, you can then set the values of the variables and you will be able to access those anyway in your app - Francis

can you show how to implement basic user/password authentication against an API? I got an API that does not require an API key but the credentials of my user on the platform

@CodeWithChris 3 года назад

Hello, most apps probably also has user and password functions but it may also return an API key that you can use instead for fast log-in, think of it as a UserID (primary key) of some sorts. i think its as simple as using network connections if its an API you can try our alamofire tutorial maybe it can help codewithchris.com/alamofire/ check out swiftyjson as well codewithchris.com/swiftyjson/ - Francis

Stupid question, but what do we do if the json starts out as an array? For instance the reddit api for comments begins with something like 1.data.children[0].replies.body I understand how to decode everything but the array (or dictionary?) in the beginning... I try decoding it as [ObjectThatContainsData] and that doesn't work either. On stack I've seen people mention ways to work with this using serialization, but as far as I know it's always better to use decoding right?

Nice video. The Facebook API would be nice. Thanks. 👍🏻😀 I have to admit, I have my own selfish motivation for that suggestion. Lol. There are billions of active FB users who use the wealth of features and services offered by FB. However, there is a glaring omission in the world of FB. It is a feature I have wanted for years... I cannot be the only one who wants it. Lol. Oh yeah... FB no longer supports their own Objective-C SDK. Thank you FB. Now I have to venture into Swift. I almost forgot... the feature I want to implement, uses a new dynamic approach to security by retrieving bare minimal information... only when it is needed. The code I have in mind will *NOT enumerate* through all friends and collect their info. *Bare minimum info only when needed.* I want to make and sell an app that works as advertised, not take advantage of people after they buy the app.
