Hi Stewart, great series, I have a quick question: How can we access data that is in a dictionary that is nested inside a mother dictionary. I know you were able to do that with arrays by using the [name of array structure] syntax, but how can I do that for dictionaries?

[ضدالظلم-دح]

You are fantastic
Thank you so much 😊
I am wondering which video editor you are using and how many hours you spend for preparing your videos
I Know that this videos take allot of time and work 👍

3:52 let person1JSONData = Data(person1JSON.utf) would do the same thing?

[josueog]

Hello Stewart, it's an excellent job, thanks for sharing your knowledge
I've tried to download the files but it's not working, maybe the link is not avaible anymore
if there is other link and you could share it would be great
thanks in advance

good job, but the playground does not want to execute starting from place with personsJSON declaration

[nancyjain]

unable to download the started project

In version 12.4, I am required to unwrap personsJSONData ... let personsArray = try! decoder.decode( [Person].self, from: personsJSONData!) ... in order for the decoding to complete . This makes some sense to me as partner is nil in the second person. Is this due to changes in the version?
