RealmSwift Problem in Xcode 14 beta. Showstopper

MongoDB Atlas App Services & Realm
1

I’m trying out the new macOS, iOS, and Xcode from WWDC22.

I’m getting the error:

Thread 1: “Keychain returned unexpected status code: -34018”

when I’m creating a RealmSwift.app with:

let ra = RealmSwift.App(id: “foody23realm-jfsbk”)

this line has worked in earlier versions.

I don’t really expect Realm to fully support Apple’s beta software, but I thought you could use a heads up about the error and I could warn other users contemplating testing it at this time.

Stack trace below:

One more note: Package version…

let coreVersionStr = “12.1.0”

let cocoaVersionStr = “10.28.1”

One more note:

This error occurs with iPhone and iPad simulators.
It also occurs with a target of My Mac (Designed for iPad)

However, it does not occur with a target of My Mac.

It’s now working with an iPhone 12 running iOS 16.

However it’s still failing in simulators and in My Mac (Designed for iPad).

5

I’m seeing the same behaviour. Works on device, not on simulators.

I had to add Keychain Sharing capability to the target to make the app works on iPhone simulators (beta 4), not sure why though…

I am having the same issue in beta 4. Adding “Keychain sharing” as a capability in targets fixed the issue for me.

I filed an issue on the GitHub repo for reference: https://github.com/realm/realm-swift/issues/7915
