Tuist 4中如何通过SPM为第三方依赖指定构建设置？

在Tuist 4的新机制下，要为SPM引入的第三方依赖（比如示例中的CrashReporter）配置额外构建设置，无需手动修改Xcode，可通过Project.swift中的dependencySettings参数实现自动配置，具体操作如下：

步骤1：确保SPM依赖已正确引入 #

先在项目根目录的Package.swift中完成CrashReporter的依赖声明：

let package = Package(
    name: "YourProject",
    dependencies: [
        .package(url: "https://github.com/xxx/CrashReporter.git", from: "1.0.0")
    ],
    targets: [
        .target(
            name: "YourTarget",
            dependencies: [
                .product(name: "CrashReporter", package: "CrashReporter")
            ]
        )
    ]
)

步骤2：在Project.swift中配置依赖的构建设置 #

在项目的Project.swift文件里，通过Project初始化器的dependencySettings字段，为指定SPM依赖设置目标构建设置：

import TuistCore
import TuistGraph

let project = Project(
    name: "YourProject",
    settings: .settings(),
    targets: [
        Target(
            name: "YourTarget",
            platform: .iOS,
            product: .app,
            bundleId: "com.yourcompany.YourProject",
            infoPlist: .default,
            sources: ["Sources/**"],
            dependencies: [
                .package(product: "CrashReporter", package: "CrashReporter")
            ]
        )
    ],
    dependencySettings: [
        .package(product: "CrashReporter", package: "CrashReporter"): [
            "USE_HEADERMAP": "YES"
        ]
    ]
)

针对不同构建配置的扩展配置 #

如果需要为Debug/Release环境设置不同的构建设置，可以使用带条件的配置方式：

dependencySettings: [
    .package(product: "CrashReporter", package: "CrashReporter"): .settings(
        base: ["USE_HEADERMAP": "YES"],
        debug: ["EXTRA_SETTING": "DEBUG_VALUE"],
        release: ["EXTRA_SETTING": "RELEASE_VALUE"]
    )
]

执行tuist generate命令后，生成的Xcode项目中CrashReporter目标会自动应用上述构建设置，与之前在Dependencies.swift中通过targetSettings配置的效果完全一致。
