Will be exploring Apple’s cktool for #cloudkit setup, which hopefully will let me populate data that will let me test sync

Roughed in a little prototype - UI mostly done, some test classes to create Tunes and TuneSets. Tomorrow rough in Collections. Nice that UIKit now lets us add UISplitViewControllers as tabs on UITabControllers.

So the next question is - create a purpose-built prototype to experiment with attributed relationships or bang away at a disposable branch of my main project? I know what I _should_ do... And it will make things easier to share here without distractions. So a new project using Storyboard (i.e. UIKit) template with CoreData. Minimum deployment will be iOS 17. No CloudKit as yet, I want to be able to test migration from ordered many:many .

Enough for tonight. Tomorrow I'll start prototyping the migration from explicitly ordered many:many to implicitly ordered via intermediate attributed relationship objects.

#iosdev #buildInPublic #coredata #cloudKit I also have make sure I'm selecting the Private database and the com.apple.coredata.cloudkit'recordName' is not marked queryable

https://lyons.app/2021/07/05/how-to-fix-field-recordname-is-not-marked-queryable-in-cloudkit/

gave me the answer: I have to modify the schema by adding a queryable index called recordName to the recordName metadata field for each record type so I can view the records. I also have make sure I'm selecting the Private database and the com.apple.coredata.cloudkit zone.

Got the demo working after some annoying debug sessions. Seems like it has not been revisited since 2022, and iOS 18 changed the behaviour of collectionView.dequeueReusableCell - as of iOS 18 it asserts if you call it outside of cellForItemAt indexpath. it was being called in awakeFromNib to set a font.

You would think that a company with the resources of Apple would at a minimum task interns to COMPILE AND RUN demos called out in the docs 11/n

There is some Apple demo code from WWDC 2022 that gives an example of deduplication on CloudKit sync. It's a simplified demo but it does give an example of a many:many (unordered) relationship. Let's see if we can get it running.

As an aside - I've learned a lot about CoreData and CloudKit from @fatbobman's blog.
