I am having issues loading my model from a Swift Package with the following structure:
| Package.swift
| Sources
| - | SamplePackage
| - | - Core
| - | - | - SamplePackageDataStack.swift
| - | - | - DataModel.xcdatamodeld
| - | - | - | - Model.xcdatamodel ( <- is this new? )
As mentioned, I am not required to list the xcdatamodeld as a resource in my Package manifest.
When trying to load the model in the main app, I am getting
CoreData: error: Failed to load model named DataModel
Code:
In my swift Package:
public class SamplePackageDataStack: NSObject {
public static let shared = SamplePackageDataStack()
private override init() {}
public lazy var persistentContainer: NSPersistentContainer = {
let container = NSPersistentContainer(name: "DataModel")
container.loadPersistentStores(completionHandler: { (storeDescription, error) in
if let error = error as NSError? {
fatalError("Unresolved error \(error), \(error.userInfo)")
}
})
return container
}()
/// The managed object context associated with the main queue. (read-only)
public var context: NSManagedObjectContext {
return self.persistentContainer.viewContext
}
public func saveContext () {
if context.hasChanges {
do {
try context.save()
} catch {
let nserror = error as NSError
fatalError("Unresolved error \(nserror), \(nserror.userInfo)")
}
}
}
}
Main App:
import SamplePackage
class ViewController: UIViewController {
override func viewDidLoad() {
					super.viewDidLoad()
	var container = SamplePackageDataStack.shared.persistentContainer
print(container)
		}
}

I asked this question here incorrectly:
https://developer.apple.com/forums/thread/651187?page=1#615966022
What I am actually trying to do is use a local .xcFramework as a Resource inside of a Swift Package without having to distribute it with the package..?
Am I supposed to create a binaryTarget as a dependency instead of it being a resource?
Im getting the error: "No such module 'SampleFramework' "
Example:
Say that my SampleFramework has a dependency on sample.xcFramework, how can I add it as a resource to use it in sample.swift
Source
// Sample.swift
// MARK: Import the local xcFramework inside of my package
import SampleFramework
struct Model {
var something: SampleFramework.something
}
Package file
// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "SamplePackage",
platforms: [
.iOS(.v13)
],
products: [
// Products define the executables and libraries produced by a package, and make them visible to other packages.
.library(
name: "SamplePackage",
targets: ["SamplePackage"]),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages which this package depends on.
.target(
name: "SamplePackage",
resources: [
.process("SampleFramework.xcframework")
								// I have also tried .copy()
]),
.testTarget(
name: "SamplePackageTests",
dependencies: ["SamplePackage"])
]
)
Structure:
| SamplePackage
| - | Package.swift
| - | README.swift
| - | Sources
| - | - | SamplePackage
| - | - | - | sample.swift
| - | - | - | SampleFramework.xcframework
| - | - | Tests
| - | - | - | LinuxMain.swift
| - | - | - | SampleTexts
| - | - | - | - | sampleTests.swift
In the talk, it was explained how to use a binaryTarget to add a .xcframework from a url, but what about a local path?
Take the following Package and file structure, is this the correct way to structure and refer to the .xcFramework?
| SamplePackage
| - | Package.swift
| - | README.swift
| - | Sources
| - | - | Sample
| - | - | - | file.swift
| - | - | SampleFramework
| - | - | - | framework.xcframework
| - | - | Tests
| - | - | - | LinuxMain.swift
| - | - | - | SampleTexts
| - | - | - | - | sampleTests.swift
// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "Sample",
platforms: [
.iOS(.v13),
.macOS(.v10_12)
],
products: [
// Products define the executables and libraries produced by a package, and make them visible to other packages.
.library(
name: "Sample",
targets: ["Sample", "SampleFramework"]),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages which this package depends on.
.target( name: "Sample"),
.testTarget(
name: "SampleTests",
dependencies: ["Sample"]),
.binaryTarget(
name: "SampleFramework",
path: "framework.xcframework")
]
)
I am getting the following error(s): invalid custom path 'framework.xcframework' for target 'SampleFramework'
target path '/framework.xcframework' is not supported; it should be relative to package root
