How to convert a FetchRequest to an array within a View init() method? Thanks for help.

You can try and map it:

var myArray: [ObjectType] = []

init(...) {
    fetchRequest = FetchRequest<MyObject>(
        entity: MyObject.entity(),
        sortDescriptors: [NSSortDescriptor(key: "order", ascending: true)],
        predicate: NSPredicate(format: "%K == %@", "someObject.id",  myPassedObject.id.uuidString)
    )
    myArray = myObject.map { $0 }
}

.. I've only done it like this before, though, when I am creating the fetchRequest within the init itself (i.e. not the @FetchRequest property wrapper), as shown. I've found it easier to extend the CoreData object itself and add a computed property.

This is taken from Donny Wals - Practical Core Data

Set up a file with

class StorageProvider {
    let persistentContainer: NSPersistentContainer

    init() {
        persistentContainer = NSPersistentContainer(name: "HelloCoreData")

        persistentContainer.loadPersistentStores { (description, error) in
            if let error = error {
                fatalError("Core Data store failed to load with error: \(error.localizedDescription)")
            }
        }
    }
}

Then you can add

func getAllMovies() -> [Movie] {
    let fetchRequest: NSFetchRequest<Movie> = Movie.fetchRequest()

    do {
        return try persistentContainer.viewContext.fetch(fetchRequest)
    } catch {
        print("Failed to fetch movies: \(error)")
        return []
    }
}

and at call site add

let storageProvider: StorageProvider
@State private var movies: [Movie] = []

then in the action movies = storageProvider.getAllMovies() eg a button

or

let storageProvider = StorageProvider()
let movies: [Movie]
init() {
    movies = storageProvider.fetchRecords()
}
