Question

我正在尝试设置合适的shebang来为iOS执行Swift脚本

#!/usr/bin/env xcrun --sdk iphonesimulator swift -target x86_64-apple-ios12.1-simulator

import Foundation
import UIKit

print("Hello, World!")

但是它不起作用。当我运行脚本时：

./myScript.swift

我在终端机上读到了

<unknown>:0: error: could not load the swift standard library

我一直在尝试不同的shebang设置以使其正常工作 #!/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift -sdk /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk -target x86_64-apple-ios12.1-simulator，但仍然没有成功。

最后但并非最不重要的一点是，运行iOS版本很重要，因为我需要导入UIKit。

感谢

/// myScript fullversion：

#!/usr/bin/swift

import Foundation
import UIKit

public class FileSystem {

    @discardableResult init() {
        let fileManager = FileManager.default

        do {
            let resourceKeys: [URLResourceKey] = [.creationDateKey, .isDirectoryKey]
            let documentsURL = fileManager.currentDirectoryPath
            guard let enumerator = FileManager.default.enumerator(at: URL(fileURLWithPath: documentsURL),
                                                                  includingPropertiesForKeys: resourceKeys,
                                                                  options: [.skipsHiddenFiles], errorHandler: { (url, error) -> Bool in
                                                                    print("directoryEnumerator error at \(url): ", error)
                                                                    exit(1)
            }) else {
                print("error, can't find directory")
                exit(1)
            }

            for case let fileURL as URL in enumerator {
                let file = fileURL.lastPathComponent
                print(file)
                // check if file is a class that conforms to protocol X 
            }
        }
    }
}

FileSystem()

./myScript.swift:4:8: error: no such module 'UIKit'
