【解决方案1】：

struct Configuration {
    static var environment: Environment = {
        return Environment.init(rawValue: Bundle.main.object(forInfoDictionaryKey: "Configuration") as! String)!
    }()

    static var documentsDir: String {
        guard let dir = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first else { fatalError("There was something wrong finding the documents directory") }
        return dir
    }
}

enum Environment: String {

    case local = "Local"
    case production = "Production"

    var googlePlistFileName: String {
        switch self {
        case .local:
            return "GoogleServiceMobileLocal"
        case .production:
            return "GoogleServiceMobileProduction"
        }
    }
}

我在 info-plist 文件中添加了一个键

这是 objc 解决方案，但可以很容易地翻译成 Swift，希望对您有所帮助：

NSString *filePath;
#ifdef DEBUG
    filePath = [[NSBundle mainBundle] pathForResource:@"GoogleService-Staging" ofType:@"plist"];
#else
    filePath = [[NSBundle mainBundle] pathForResource:@"GoogleService-Production" ofType:@"plist"];
#endif

FIROptions *options = [[FIROptions alloc] initWithContentsOfFile:filePath];
[FIRApp configureWithOptions:options];

tom-baranowicz answer 的 Swift 版本

#if DEBUG
    let path = Bundle.main.path(forResource: "GoogleService-Staging", ofType: "plist")
#else
    let path = Bundle.main.path(forResource: "GoogleService-Production", ofType: "plist")
#endif
if let options = path.flatMap({ FirebaseOptions(contentsOfFile: $0) }) {
    FirebaseApp.configure(options: options)
} else {
    // handle failed configuration here
}
