请参阅 connecting to multiple projects 上的 Firebase 文档，其中显示了适用于 iOS 的内容：

// Configure with manual options. Note that projectID and apiKey, though not
// required by the initializer, are mandatory.
let secondaryOptions = FirebaseOptions(googleAppID: "1:27992087142:ios:2a4732a34787067a",
                                       gcmSenderID: "27992087142")
secondaryOptions.apiKey = "AIzaSyBicqfAZPvMgC7NZkjayUEsrepxuXzZDsk"
secondaryOptions.projectID = "projectid-12345"

// The other options are not mandatory, but may be required
// for specific Firebase products.
secondaryOptions.bundleID = "com.google.firebase.devrel.FiroptionConfiguration"
secondaryOptions.trackingID = "UA-12345678-1"
secondaryOptions.clientID = "27992087142-ola6qe637ulk8780vl8mo5vogegkm23n.apps.googleusercontent.com"
secondaryOptions.databaseURL = "https://myproject.firebaseio.com"
secondaryOptions.storageBucket = "myproject.appspot.com"
secondaryOptions.androidClientID = "12345.apps.googleusercontent.com"
secondaryOptions.deepLinkURLScheme = "myapp://"
secondaryOptions.storageBucket = "projectid-12345.appspot.com"
secondaryOptions.appGroupID = nil

但请阅读整个页面，因为还有更多步骤，具体取决于您的具体要求。
