Nice way you showed us to add default data at app launch. Thank you.

[chezchezchezchez]

You are a lifesaver dude!
This solved my whole problem!

[tech_ch]

Here we have some really helpful stuff, appreciated Tunds 🙆🏻‍♀

[corey]

Nice set of videos, thanks. Is it possible to pre-load data with a relationship? In your example can you import a to do that already has a category assigned?

[dmitrygolovin]

Great stuff! Would be cool to see repeatable daily, weekly, monthly, yearly tasks.

[Ride]

Great work tunds! My question is how would you do this to have some preloaded toDos? Would you have to create the extension on the toDoItem and then init each one?

[NICKLIFE]

Is there a reason you used actor ItemContainer but in the preview lesson you just used a struct?

[PaulSmithGainesville]

This video let me to you and I’m subscribed and plan to watch several. Great job on these!! I am new to SwiftData and this video helped me realize that I can create a class and initiate in App and inject it into the views. But I cannot figure out how to create a reference to the ItemsContainer outside a View. In my app, I need to call an API and pass JSON, but can’t get to the SwiftData model to create it within my class that calls the API. Have you covered this in any of your videos?

[milanlabus]

What if you had a model thats unrelated to the other models how would you specify that modelContainer

[lfan_tv]

Hi Sir, what if i use this method to store the data, for the next version of my app, i want to add more preload category, how can I do it?

[DefeatOG]

Great video! I have a question. My data preloads correctly, however now when I go to make a new "category" it does not save. If I delete a default category it will update and remove it but it seems like anything outside of the default data now does not get saved. It did before this, and if I don't use the ItemsContainer and just do it like before then everything works fine. Any idea?

[holycrosscv]

This is really well done! Thanks so much for this great instruction.
I am stuck trying to safely unwrap the container. Is there a way to return a default ModelContainer?
Thanks!

[Alan-ucpf]

yours videos are awesome, with good examples😂

[NormNorris]

Very good series of videos. Pre-filling a small amount of data works great. What about when you have a large json file of data you would like to pre-fill to SwiftData. Obviously this works but the app sits with a blank screen while this happens. Thoughts on how to show some sort of progress view? Challenging because you don't use .onAppear or .task in the ContentView where one could display a progress view.

[cloftis]

As always nice work. I wonder if you could set this up based on a query instead of a boolean. If the query/fetch returned empty, you could then prepopulate with categories. Thanks for the great video and education.

[grin_phi]

Great video Tunds. Really helped me. I'm now working on making the once only set up (i.e. create categories) work across multiple devices. Thinking of turning the @appstorage firstRun property into a ubiquitous key value pair. Any tips?

[finchicoph]

How about pre-populating SwiftData with a huge data from an sql file? Checking on the docs I don't think SwiftData can do it out-of-the-box. How would you suggest to do it? Use Core Data?

[AliouSARR]

Great video.
I have a question can we use switData in a UIKit project ?
Thanks

[holycrosscv]

Beta 8 errors when it tires to create the ModelContainer. "Cannot convert value of type 'ModelConfiguration' to expected argument type 'any PersistentModel.Type'" Same error for schema. Any clue what is going on?
Thanks!
