**********************************

In this SwiftData tutorial, we're going to look at how we can improve our apps performance by using SwiftData Background Tasks. We'll look at how we can use background threads in SwiftData to help us handle saving large amounts of data without affecting our apps performance.

We'll also look at how we can use Xcode Instruments to validate and make sure that the data that we've saving is being done on a thread that isn't the Main Thread to avoid performance issues.

Nice video as always and yes... tutorial about Profile in Instruments!

[SkoroVideo]

Awesome video, thanks! YES! I'd really love to see a tutorial about instruments

[chezchezchezchez]

Yes! A video 2:50 with that tool with be great.

[keegan]

Thank you 🙌 do you have any videos on how to query it not on the main thread like you mentioned at the end?

[chezchezchezchez]

Can you expand on the "Write a predicate to fetch data" (to avoid the @Query on the main thread)
My app uses a LOT of @Querys and the main thread is bogged down!
I need more speed.
Thanks!

Excellent video on ModelActor macro. It was very helpful.

[jayelevy]

great video, as always. +1 on a video on instruments!! I have a swift data project that is really bogging down when initiating a view that includes a dynamic filter predicate. I have no idea how to troubleshoot. thanks for what you do

[AdelUI]

Thanx for amazing video, but is it working also when i want to update data ?

[ammarahmad]

When you set "Strict Concurrency Check" to "Complete", you will get a warning the message "Non-sendable type returned by call to actor-isolated function cannot cross actor boundary", How can void this.

Why create an actor who you just reap everything into Task{let modelContext = ModelContext(container) ...} ?
