ios – XCFramework with SPM dependencies doesn’t expose them to undertaking it is utilized in

I’ve library that may be a SPM package deal. It has one dependency.

// swift-tools-version: 5.9
// The swift-tools-version declares the minimal model of Swift required to construct this package deal.

import PackageDescription

let package deal = Package deal(
    title: "ExampleLibrary",
    platforms: [
            .macOS(.v10_15), .iOS(.v13), .tvOS(.v13)
        ],
    merchandise: [
        // Products define the executables and libraries a package produces, making them visible to other packages.
        .library(
            name: "ExampleLibrary",
            type: .dynamic,
            targets: ["ExampleLibrary"]),
    ],
    dependencies: [
        .package(url: "https://github.com/krzyzanowskim/CryptoSwift.git", .upToNextMajor(from: "1.8.1")),
    ],
    targets: [
        // Targets are the basic building blocks of a package, defining a module or a test suite.
        // Targets can depend on other targets in this package and products from dependencies.
        .target(
            name: "ExampleLibrary",
            dependencies: ["CryptoSwift"]),
        .testTarget(
            title: "ExampleLibraryTests",
            dependencies: ["ExampleLibrary"]),
    ]
)

This library is then construct an exported to binary XCFramework and distributed as one other SPM package deal

// swift-tools-version: 5.9

import PackageDescription

let package deal = Package deal(
    title: "ExampleMobileSDK",
    platforms: [
        .iOS(.v13),
        .macOS(.v10_15),
    ],
    merchandise: [
        .library(
            name: "ExampleMobileSDK",
            targets: ["ExampleLibraryFramework", "ExampleMobileSDK"]),
    ],
    targets: [
        .binaryTarget(name: "ExampleLibraryFramework", path: "ExampleLibrary.xcframework")
    ]
)

after I import this package deal to an app for utilization and use

import ExampleLibrary

I’ve on this line error Lacking required module 'CryptoSwift'

Once I import CryptoSwift within the app as one other package deal dependency I’ve an error:

objc[5702]: Class _TtC11CryptoSwift15XChaCha20Worker is applied in each [...]/ExampleLibrary (0x1016edcf0) and [...]/instance.app/instance (0x100611908). One of many two might be used. Which one is undefined.

Additionally after I add to my XCFramework Package deal CryptoSwift dependency it additionally stops exhibiting the error however the duplicate import is similar.

// swift-tools-version: 5.9

import PackageDescription

let package deal = Package deal(
    title: "ExampleMobileSDK",
    platforms: [
        .iOS(.v13),
        .macOS(.v10_15),
    ],
    merchandise: [
        .library(
            name: "ExampleMobileSDK",
            targets: ["ExampleLibraryFramework", "ExampleMobileSDK"]),
    ],
    dependencies: [
        .package(url: "https://github.com/krzyzanowskim/CryptoSwift.git", .upToNextMajor(from: "1.8.1")),
    ],
    targets: [
        .target(name: "ExampleMobileSDK", dependencies: ["CryptoSwift"]),
        .binaryTarget(title: "ExampleLibraryFramework", path: "ExampleLibrary.xcframework")
    ]
)

1. How can I disable exposing CryptoSwift from my library so it may be imported within the app with out duplicates? I’ve tried utilizing @_implementationOnly import CryptoSwift inside my library but it surely didn’t stopped exposing it after I import one other CryptoSwift in app.
2. Methods to make the app undertaking see that this dependency is embedded contained in the XCFramework. That is how XCFramework appears to be like like inside:
