Great tutorial. I like that you demonstrated encapsulation of the network request.

[@rasty_habibi]

This is such an excellent tutorial. Great job explaining the awesome tools + methods built into Swift. Thank you Brian.

[@traviss7740]

This was incredibly useful. I'll be watching these from now on for learning. Quick and to the point.

[@Patrick462]

Great tutorial, very helpful! I appreciate how you focused on the topic and did not ramble off on tangential issues (as many tutorials do).

[@michaelt9241]

Thanks for this video! I had been searching how to parse JSON successfully from a GET request for a while.

[@swaimcs9827]

Knowledge full video

[@mohammedsulaiman5126]

Hey Brain Thank u so much It helps!!! Make tutorials more on this topic Thanks in advance!

[@elenekotu]

Bad idea to show your app key with all these trolls on internet 😂 nice video!

[@prosyarceno6607]

Is it that dangerous considering it's only a tutorial with some sample data readily available on the net?

[@elenekotu]

I know guys, it was just a joke comment

[@shabba194]

I enjoy you content. Straight to the point and easy to follow

[@dk-sky3820]

This is a great tutorial. Thank you. I wish more tutors would stop using storyboards though 😑

[@peronawu9265]

Just wanna say thank you, Brian, this tutorial helps me a lot.

[@josiahrininger]

Very clean way of handling your API request!🙌🏻

[@lycansre]

your tutorial is amazing. Good job and a nice effort.

[@iOSTechie]

Thank you so much Brian for such a great video. 😊👍 Can you please make a video where you can show us how to do API calls like get post delete upload in iOS. Love your channel

[@rukimakino2533]

Oh this helps a lot !!! Thanks !!!

[@thorstengonschior5603]

Hey Brian, thx a lot! Adapted the request method it into my own project and it worked right away :)

[@1358raha]

great point . thanks a lot ... you save my days bro ... I'm new in swift codes and I want to scrap data from a website that I have not json data in my result . how I can get api-key of this website ? is another way to get API s a websites we need their data ?

[@yrist12]

You can use Postman to make requests with any type of parameters and get cool printed JSON in response. Also use QuickType to convert JSON text to swift codable model

[@agustino.4325]

Thanks a lot for the QuickType discovery, hadn't heard of it, but I can see myself using a lot from now on!!

[@AshlandTrades]

Hi Brian, Do you have the source code for this project? I cant seem to figure out what I'm getting wrong

[@linusb212]

This is a great tutorial! I am struggling to understand the escaping completion handler of the request function. Can you offer any feedback to explain the high level logic of that code?

[@JohnKitching1963]

Great work Brian. Can you talk us through the steps to get to your starting point please? I've tried a few ways but never get a tableviewcontroller in the swift file. I'm using Xcode 11

[@ZAP1able]

We are waiting for Post method 🙏🏻

[@konig231]

amazing tut bro!

[@exalandconcept]

Very great Tutorial , clear and very well explained

[@andronisaev]

Thank you very much for a great video! So useful and easy to understand! Could you please explain why you did not use [weak self] when updating tableView in didSet?

[@priyankamistry2168]

Nice tutorial. How can we store this json data directly to core data using codable and access it?

[@oisbelsimpsonverdecia9458]

Hello. Can you do a video about GET or POST request to an API that the server require Basic Auth in Swift 5. There is some info about a delegate implement authentication challenge but is not clear. Thank you in advance.

[@edmfestivals6066]

goddamn swift makes you do alot just to send a request

[@alcprado]

Awesome tutorial, Brian!

[@Borelzin_]

Thanks man, helped me a lot!!

[@truthbetold5460]

Well explained

[@faustogomez7731]

Good video, it helped me a lot.

[@Ivan_Maslov]

Hello! Could you tell me why did you update holidays list on main thread? As far as I know, the property is already located on the main thread, since it initializes after applicationDidFinishLaunch

[@yrist12]

You should to cancel dataTask before make new one. Because new task can be responded faster than old one and you will see old results

[@GG-hk5iz]

SWEET AND SIMPLE

[@glennmiller394]

I couldn't find the rested app. Is it still available?

[@Andy-vc8ir]

If I want to request json from multiple different URL's using the same API key, do I need to implement a separate request per URL?

[@hansholzbein1]

thanks bro

[@princemoronfolu]

Hey Brian, i don't think the searchBarButtonClicked is firing.

[@HarvMasterJay]

Hey Bolaji, did you find a fix for this? I think I'm having the same issue as you

[@princemoronfolu]

@@HarvMasterJay i used func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) { it fires every time text changes but at least it works.

[@HarvMasterJay]

Awesome man and thanks! Take care!

[@bruhrnav]

Why is there a 'women' search on your Rested?

[@joshkinney5091]

can you explain the [weak self] @ 27:00 ?

[@FilipKrzyz]

I also don't understand necessity for it here

[@GeraldBrigen]

Is used to prevent retain cycles, check this article it explains it in greater details www.avanderlee.com/swift/weak-self/.

I did exactly what you did, but I got a "canNotProcessData" error......

[@GeraldBrigen]

I was experiencing the same error, the issue might be your model keys are not matching those from the API, I created a gist you can compare to see where you went wrong gist.github.com/gbrigens/71e29f2a40178870188500dc3d023c7d.

[@saunderstech7430]

how can I get the files

[@9988khan]

plz give Link of project source

[@joshkinney5091]

not exactly the same code. the look is a bit different and some names have been changed. but overall its the same code and it is working. github.com/jbird84/HolidaysUsingAPIs

[@rajatkotian8887]

Does this mapping technique work with any api's we work with?? Anyone can ans please..

[@BrianAdvent]

Sure, but you will have to adapt the data model to the api you are using

[@rajatkotian8887]

@@BrianAdvent Okay thanks Brian... Great content!

[@platin2148]

749ms off response time man thats pretty bad wouldn't use such a slow service.

I don't fully understand all the code produced, but I found this to be very helpful in trying to create proper structs for JSON output: app.quicktype.io/

You are being lazy. Make complete tutorials not partial.
