iOS 应用程序中全局常量存储在哪里

在iOS应用程序中，全局常量可以存储在不同的地方，具体取决于开发人员的需要和偏好。以下是一些常见的存储全局常量的方式：

swift
struct Constants {
    static let apiKey = "your_api_key"
    static let baseURL = "https://example.com"
}

swift
let apiKey = Constants.apiKey
let baseURL = Constants.baseURL

swift
class AppConstants {
    static let apiKey = "your_api_key"
    static let baseURL = "https://example.com"
}

swift
let apiKey = AppConstants.apiKey
let baseURL = AppConstants.baseURL

swift
enum Constants {
    static let apiKey = "your_api_key"
    static let baseURL = "https://example.com"
}

swift
let apiKey = Constants.apiKey
let baseURL = Constants.baseURL

APIKey
your_api_key

swift
if let apiKey = Bundle.main.object(forInfoDictionaryKey: "APIKey") as? String {
    // 使用apiKey
}
