Axel Le PennecWell, too good to be true... 😢<a href="https://iosdev.space/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> inheritance is only available for iOS 26, as specified in the <a href="https://iosdev.space/tags/WWDC25" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WWDC25</a> session and the new article "Adopting inheritance in SwiftData".Article: <a href="https://developer.apple.com/documentation/swiftdata/adopting-inheritance-in-swiftdata" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://developer.apple.com/documentation/swiftdata/adopting-inheritance-in-swiftdata</a>

Axel Le PennecOh! <a href="https://iosdev.space/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> inheritance seems to be available on iOS 17+!Documentation: <a href="https://developer.apple.com/documentation/swiftdata/schema/entity/superentity" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://developer.apple.com/documentation/swiftdata/schema/entity/superentity</a><a href="https://iosdev.space/tags/WWDC25" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WWDC25</a>

Aleksander StojanowskiI prepared a great surprise for myself… I was sure the <a href="https://iosdev.space/tags/WWDC25" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WWDC25</a> starts tomorrow. 🙈 I wasn’t even hyped yet, but I’m now, since this morning. 😁 I don’t have any expectations, but everything related to <a href="https://iosdev.space/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> & <a href="https://iosdev.space/tags/SwiftUI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftUI</a> will be great. 😁

Helge HeßIf you want to toy around with <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a>, but need some sample data, I have that <a href="https://mastodon.social/tags/Northwind" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Northwind</a> import. Which took a loooong time, but once it is in, it's ok 🙂 <a href="https://github.com/Northwind-swift/NorthwindSwiftData" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/Northwind-swift/NorthwindSwiftData</a>

Deirdre Saoirse MoenAdventures in mystery: if you use @Attribute(.externalStorage) in your <a href="https://hachyderm.io/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> app, how can you determine whether or not your data is stored in your db or externally?Where's it stored in a Document-based app on macOS?Fun times from exploring an (unrelated) db migration issue.<a href="https://deirdre.dev/posts/swift-data-images/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://deirdre.dev/posts/swift-data-images/</a><a href="https://hachyderm.io/tags/swift" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#swift</a>

Patrick McConnellI restored my <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> backing store via Time Machine today. Sometimes this stuff still works.I keep corrupting the store by double clicking documents that open an older schema version from the trash. sigh.<a href="https://mastodon.social/tags/macOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#macOSDev</a>

FlorianGot it fixed thanks to <a href="https://hachyderm.io/@freiwald" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@freiwald</a> Store the entries in an array and write this array to the parent using append(contentsOf:) at once. Also very important: neither define inverse relations in the child model nor use them for insertion! I am now able to write 200k entries in 37s. <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a>

FlorianAm I missing something, or are relationships in <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> incredibly expensive? Inserting just 2,409 entries with a relationship takes 21s, compared to 0.5s without. Autosave is off, and I'm manually saving every 1,000 entries. What am I doing wrong?<a href="https://mastodon.social/tags/iOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#iOSDev</a> <a href="https://mastodon.social/tags/Swift" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Swift</a>

Michael RoweMy new jobby, job requires that I keep track of project time (It has been YEARS since I’ve had to do that). So I spent today doing a bit of coding and am ready to test out my time tracker this week. <a href="https://mstdn.social/tags/apple" class="mention hashtag" rel="tag">#apple</a> <a href="https://mstdn.social/tags/developer" class="mention hashtag" rel="tag">#developer</a> <a href="https://mstdn.social/tags/swift" class="mention hashtag" rel="tag">#swift</a> <a href="https://mstdn.social/tags/swiftui" class="mention hashtag" rel="tag">#swiftui</a> <a href="https://mstdn.social/tags/swiftData" class="mention hashtag" rel="tag">#swiftData</a>

sandorOkay, so my crossposting app for Mastodon and Bluesky is taking shape now. ViewModel needs some cleanup with optionals (a side effect of making the <a href="https://social.appbakery.ee/tags/swiftdata" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> <a href="https://social.appbakery.ee/tags/cloudkit" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CloudKit</a> compatible) <a href="https://social.appbakery.ee/tags/bluesky" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#bluesky</a> <a href="https://social.appbakery.ee/tags/mastodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mastodon</a> <a href="https://social.appbakery.ee/tags/ios" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ios</a> <a href="https://social.appbakery.ee/tags/swift" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#swift</a>

Patrick McConnellFigured out why my <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> store was getting corrupted when no testers have seen this issue or even had a crash yet.If I double clicked a file to be opened in my app Finder was digging out some old build from the trash with an old schema. Inverse of works on my machine. Can only fail on my machine. Not helpful.<a href="https://mastodon.social/tags/macOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#macOSDev</a>

Patrick McConnell<a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> <a href="https://mastodon.social/tags/macOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#macOSDev</a> <a href="https://mastodon.social/tags/iOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#iOSDev</a>do this instead:var myContainer = myModelContainer()WindowGroup { MyView() } .modelContainer(myContainer())

Patrick McConnellUsing <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> and you're instantiating your container inline with the Window creation something like this:WindowGroup { MyView() } .modelContainer(myModelContainer())Will work fine on a Mac. The same thing on iOS will fail if you rotate the device or otherwise cause the Window to be recreated. The model context will be reset/recreated throwing an error.Instantiate the container in your structure and pass that instead and all is good.Ask me how I know?<a href="https://mastodon.social/tags/macOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#macOSDev</a> <a href="https://mastodon.social/tags/iOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#iOSDev</a>

Malcolm HallFound another bug in <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> and submitted Feedback this time with a Swift Testing suite to see if that helps get it fixed faster:FB17593538: Inserted child model loses its relation to parent upon save if a fetch for the parent is done using includePendingChanges false in between insert and save<a href="https://github.com/feedback-assistant/reports/issues/658" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/feedback-assistant/reports/issues/658</a>Note: Core Data can do this without issue.

Patrick McConnellApparently since I launched my TestFlight beta for Cartographer something has broken with <a href="https://mastodon.social/tags/SwiftData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SwiftData</a> and now the app crashes at launch. Unclear if it's just my machine as I don't see any tester crashes reported.Happy Monday everyone!<a href="https://mastodon.social/tags/macOSDev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#macOSDev</a>
