我使用 SPM 将包添加到我的项目/应用程序中。在包文件中，我想将目标设置为依赖项。每当应用程序尝试构建时，我都会收到此错误。

// swift-tools-version:5.5
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription

let package = Package(
    name: "Sycra",
    products: [
      
        .library(
            name: "Sycra",
            targets: ["Sycra"]),
    ],
    dependencies: [
        .package(url: "https://github.com/NordicSemiconductor/IOS-nRF-Mesh-Library", .upToNextMinor(from: "3.2.0"))
        
    ],
    targets: [
         define a module or a test suite.
         
        .target(
            name: "Sycra",
            dependencies: ["NordicMesh"]),
        .testTarget(
            name: "SycraTests",
            dependencies: ["Sycra"]),
    ]
)

文件结构

错误

dependency 'NordicMesh' in target 'Sycra' requires explicit declaration; reference the package in the target dependency …

我想使用 new 从照片中选择图像，PHPickerViewController并且想PHPicker在加载控制器时直接打开。

像这样

import UIKit
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
         // Do any additional setup after loading the view.
         // TODO: - Here I want PhotoPicker
       }
    }
