Description

I'm using FireStore at my current iOS project and I realized that when generate CollectionReference or DocumentReference, FireStore starts keep on using CPU (around 10%) until app close.

I'm using

• Firebase 9.5.0
• install with SwiftPackageManager
• Xcode version 13.4.1 (13F100)

Here is sample code (same as document).

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
    FirebaseApp.configure()
    let db = Firestore.firestore()
    db.collection("Collection").document("test").setData(["lastLoginAt":Date()], merge: true)

    // Even this code happens issue ↓
    // let ref = db.collection("Collection")

    return true
}
