I am facing this issue only in iOS real device iOS 17.2. Simulator iOS 17.2 works fine. Here is the link to repository OkioReproduce.

This issue can be reproduced using 3.6.0 Okio version and also with latest 3.9.0 version. I hope you can solve this as soon as possible. I have tried my best to help you with reproducing. Here is line that causes this bug FILESYSTEM.openReadWrite(tempPath, mustCreate = false, mustExist = false).

@swankjesse I have created new issue for that bug

[saparbekuly]

I am also facing this problem @swankjesse. Can you help us with this?

[Stevespear426]

I'm seeing it as well. Simulator works fine, crashes with iPhone 12 on iOS 17.5.1. I'm getting it through Jetpack Datastore though.

Same here with Compose Multiplatform and Datastore. Any updates?

[Stevespear426]

I was able to fix by switching from NSDocumentDirectory -> NSCachesDirectory When creating the DataStore object on iOS.

actual fun getDataStore(name: String): DataStore<Preferences> {
    return PreferenceDataStoreFactory
        .createWithPath(
            scope = CoroutineScope(Job() + Dispatchers.IO),
            produceFile = {
                val documentDirectory: NSURL? = NSFileManager.defaultManager.URLForDirectory(
                    directory = NSCachesDirectory,
                    inDomain = NSUserDomainMask,
                    appropriateForURL = null,
                    create = false,
                    error = null,
                )
                (requireNotNull(documentDirectory).path + name + ".preferences_pb").toPath()
            }
        )
}

[swankjesse]

Unclear what action to take here. Can you reproduce this exception consistently? Or perhaps only when the device is locked?

[Stevespear426]

It was 100% reproducible at the time with NSDocumentDirectory since switching to NSCachesDirectory I haven't had any issues. I suppose the action here would be to fix using NSDocumentDirectory? Or perhaps documenting that it is not supported?
