iphone:通过代码在Target的设置中获取User Defined变量？

import Foundation

func getUserDefinedVariable(key: String) -> String? {
    guard let value = Bundle.main.object(forInfoDictionaryKey: key) as? String else {
        return nil
    }
    return value
}

if let userDefinedVariable = getUserDefinedVariable(key: "YOUR_VARIABLE_KEY") {
    print("User Defined Variable: \(userDefinedVariable)")
} else {
    print("User Defined Variable not found")
}
