SwiftData CloudKit Sync - The Complete Guide

In this video, Mohammad Azam will demonstrate how to integrate SwiftData with CloudKit. Azam will discuss in detail all the required steps you need to setup CloudKit syncing for SwiftData application.
Azam will also cover how you should use built-in @.Query macros to enable tracking and live syncing on multiple devices.
CORRECTION: If you are looking at CloudKit console dashboard, you will be able to find the records under the zone labels as such "com.apple.com.coredata.cloudkit.zone". I believe in the video, I mentioned _defaultZone, which is incorrect. Just use the dropdown to select the correct zone.

This guy is an excellent teacher and I find his teaching technique really helps my learning. Undoubtably one of the best instructional courses on iOS dev I have come across. Thank you

[@mohammadazam3177]

Thank you so much!

Thanks for the video! It would be really useful if you added sections, especially in such a long video!

Great examples, which has many excellent tips and tricks I wasn’t aware of. Thank you so much for the great work.

[@FuzeGamer11]

Really helpful video, thanks!

[@gccount]

very detailed, very practical

[@vince-the-prince]

Super helpful!

[@hurolinci5986]

Very helpful. who would´ve tot that getting rid of all the yellow messages would solve all the problems.

[@NiceLasers]

Great video!

[@kiransankarpati]

Can it work if we deploy the app through ad hoc mode, Sir?

[@w0mblemania]

Firstly, thank you very much for this. It was excellent, and a lot of help. Secondly... SwiftData and CloudKit support... it seems very janky right now. Also, do we have any idea how SwiftData migrations work with CloudKit? i.e. do the migrations also update the CloudKit records and do all the required magic?

[@azamsharp]

SwiftData and CloudKit works fine for me when using the @Query macro since Query macro enables tracking. I have not done migrations with CloudKit but I assume if you add any new properties then those should be optionals or must have a default value.

[@jamesmartin46]

Very good I learned a lot, but it was a bit too high level for me. He assumed you had a level of understanding about SwiftData/Coredata, which I don't and he didn't explain some of the basics of what he was doing., Also, he kept using keyboard shortcuts to do things that did not show on the video so I could not replicate what he did. I also did not understand why he spent so much time on getting the Preview to work and the complications that arose from that got me lost and confused so I gave up after 38 minutes.

[@azamsharp]

I recommend watching introduction to SwiftData videos first before diving into advanced stuff.

[@ryantcb]

just excellent

[@keegan8176]

Love your youtube videos and watching all of them. Just wondering, would this work the same way with syncing data between the watch app and phone app?

[@azamsharp]

I have never tried it on the watch app but I am assuming that it should be the same.

[@davemckee5252]

Thanks!

[@uguraltnsy]

It works fine for the IOS platform, but I want to use it for VisionOS, I did everything the same way, but I get the error "CloudKit Invalid bundle ID for container"

[@nroose]

Seems bad that when we get an error, we can't use the huge amount of text in the error to help us find the problem, we just have to know or guess what the problem is.

[@whatwhatmeno]

For this to work the users need to have space in their Icloud ? also can I read the users notes or not

[@rafaelplinio6527]

If my app supports CloudKit, what happens if I have a ToDo app with items saved, delete the app and local data? Will the data be back when I install again because of iCloud or will it be gone?

[@lucaknaup]

Is it possible to share data between different iCloud users with SwiftData?

[@azamsharp]

From what I have read I believe SwiftData currently only works with user's private database.

[@financelician3564]

Any idea on when that will be available? @@azamsharp

[@azamsharp]

@@financelician3564 No idea.

[@allenwixted1992]

@@azamsharpI think you can declare a public database

[@azamsharp]

Hi Allen, Any resources for public databases?

[@rwilson1125]

Pita here: I am stuck at the List( vegetable.notes ?? [] step. Xcode is telling me that "Initializer 'init_:rowContent' requires '[Note]?' conform to "RandomAccessCollection". Does not @Model do this for us? I am Xcode 15.0. Are you on a beta ahead?

[@azamsharp]

Yes. Once you conform the Note model to Model macro it should work. Move forward in the video little bit more as we end up not using vegetable.notes.

[@rwilson1125]

@@azamsharp yes, progessed to end of the video, now it compiles, but adding a note in the simulator crashes.
