    ios - Error when performing SwftData insert from share extension - Stack Overflow

    programmeradmin4浏览0评论

    I'm trying to perform a SwiftData insert from my share extension. Both app and extension are in the same App Group. I'm using the same container for both:

    public func ConfigureModelContainer() -> ModelContainer {
    let schema = Schema([Yerl.self, Category.self])
    let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false)
    
    do {
        return try ModelContainer(for: schema, configurations: [modelConfiguration])
    } catch {
        fatalError(error.localizedDescription)
    }
}

    and in the extension I save like this:

    private func saveAction() {
        let container = ConfigureModelContainer()
        let modelContext = ModelContext(container)
        
        if let defaultCategory = getDefaultCategory(container: container) {
            let foo = Foo(name: text, note: "", url: url, category: defaultCategory)

            modelContext.insert(foo)
            
            do {
                try modelContext.save()
            } catch {
                print("Error: can't save model context: \(error.localizedDescription)")
            }
        }
        
        contextpleteRequest(returningItems: [])
    }

    When I execute the line with the insertion the app goes away for about 13 seconds and then

    Thread 1: EXC_BAD_ACCESS (code=2, address=0x16a6bbfd0)

    Am I doing something unsupported? The console is silent. Access to the paramters to Foo are fine, I've tried this with local text and url arguments with the same result.

    Edit: I'm fetching successfully, it's the insert that's not working.

    • try using only one ModelContainer/ModelContext, that you pass around the views and functions, instead of creating new ones every time you call saveAction() – workingdog support Ukraine Commented Feb 17 at 23:04

    I had been following the methodolgy laid out in https://www.merrell.dev/ios-share-extension-with-swiftui-and-swiftdata/ but hadn't followed it exactly. It turns out if I pass the newly constructed container from the ViewController to the SwiftUI view like this:

    let contentView = UIHostingController(rootView: ShareView(context: context).modelContainer(modelContainer))

    then in the SwiftUI view @Environment(.modelContext) private var modelContext

    yields a good ModelContext. I'm scratching my head a little, but it works.
