问题 I'm trying to install firestore in my project. when I'm trying to install that, Xcode displays fatal error: module map file '/Users/account/Documents/myapp/Pods/Headers/Private/openssl_grpc/BoringSSL-GRPC.modulemap' not found or sometimes another errors.... so I've spend so many of times (almost entire 2 days) to solve this problem, but nothing is actually working :/ (deleting derived data and Pods folder, pod deintegrate, pod install and update or cleaning build (Command-shift-k)). platform

问题 I am trying to optimize the number of reads my app makes on Firesbase and reviewing the way I use snapshot to monitor real time changes. Imagine I have a snapshot returning the 10 latest documents like the following: db.collection("cities") .where("state", "==", "CA"). .orderBy('dateadded', 'desc').limit(10) .onSnapshot(function(snapshot) { ... }) The doc says The snapshot handler will receive a new query snapshot every time the query results change (that is, when a document is added, removed

问题 I have a Firebase Auth that stores the users, but it also builds a collection of users in the Cloud Firestore database. I can grab the users first name, but the problem I have is that it is always the last user that was added. here is my function in swift func welcomeName() { let db = Firestore.firestore() if let userId = Auth.auth().currentUser?.uid { var userName = db.collection("users").getDocuments() { (snapshot, error) in if let error = error { print("Error getting documents: \(error)")

问题 I'm trying to filter data from Firestore with Angularfire's Querying Collection: https://github.com/angular/angularfire2/blob/master/docs/firestore/querying-collections.md I'm a bit confused with the approach. I have managed to filter through a button but I do not know how to reset or remove that filter once done. What is the correct way to filter and reset said filter?

问题 I am implementing Firestore data storage in one of my apps. I have a listener which follows updates in the "logs" collection like so: db.collection("logs").addSnapshotListener({ (snapshot, error) in guard let s = snapshot else {return} if s.metadata.isFromCache { print("LOG_C \(s.documentChanges.count)") return } print("LOG \(s.documentChanges.count)") // other code }) During testing, I've been uploading documents to this collection and then I removed all of them through Firebase console. So,

问题 I am trying to use an options array in my react app, that uses react-select for the form and where the options are stored in a firebase collection. This all works fine when I define a const in the form with an array of options that I define with key value pairs, but I'm struggling to figure out how to replace that array with the collection stored in Firebase (Cloud Firestore). In my form, I currently have: const options = [ { value: "neurosciences", label: "Neurosciences - ABS 1109" }, {
