I have a kmm project, I am able to get the data from the kotlin version, but for iOS not. I am getting an exception break with code: Thread 4: EXC_BAD_ACCESS (code=EXC_I386_GPFLT)
The data from the repo that I am trying to get:
suspend fun getRestaurantsOrders(): CommonFlow<List<Order>> {
val userId = appService.currentUser!!.id
val restaurant = realm.query<Restaurant>("userID = $0", userId).first().find()!!
return withContext(Dispatchers.Default) {
realm.query<Order>("restaurantID = $0 && totalQuantity > 0 SORT(discount DESC)", restaurant._id.toString())
.asFlow().map {
it.list
}.asCommonFlow()
}
}
The way that I am trying to get data from ios:
func getOrdersList()
{
Task{
do{
try await repo.getRestaurantsOrders().watch(block: {orders in
self.restaurantActiveOrdersList = orders as! [Order] //breaks here
})
}catch{
print("error")
}
}
}
Any idea what I am doing wrong?
I am new at swift, thanks in advance!

Situation
Hi there,
I am developing an iOS app and while building my project I run into the following error message:
Error: Trace/BPT trap: 5
I didn't find anything online to fix this problem, so I wanted to know, if anyone here might be able to help.
I also had issues with Cocoapods and my Silicon Mac, so I want to list my steps I've tried fixing:
Setup
M1 MacBook Pro, macOS 11.1
XCode Version 12.4
Cocoapods with Pods for Firebase Swift, Auth, Firestore and Storage
Steps I tried fixing
cmd + shift + k for cleaning the build folder
closing XCode and opening Terminal using Rosetta
delete ~/Library/Developer/Xcode/Derived Data - Folder
pod deintegrate in project directory
delete Podfile.lock, app.xcworkspace, Pods directory
pod install
in app and pods projects build settings setting Excluded Architectures for any iOS Simulator SDK to arm64
setting Build Active Architecture Only to yes
convert Pods Project to Swift 5
build Pods Project
build app project
And then the following error occurs:
Log
Log enty from Merge swiftmodule (x86_64):

(Log way to long, exceeds character limit).
Code
As the error somewhere tells, it occured while trying to serialize the class BaseViewModel, here's the code from the Base.swift file I wrote containing that class:
import SwiftUI
import Firebase
import FirebaseFirestore
import Combine
protocol BaseModel: Identifiable, Codable {
var id: String? { get set }
var collection: String { get }
init()
}
class BaseViewModel<T: BaseModel>: ObservableObject, Identifiable, Equatable {
#Published var model: T
var id: String {
didSet {
self.model.id = id
}
}
var cancellables = [AnyCancellable]()
private var db = Firestore.firestore()
required init(){
let model = T.init()
self.model = model
self.id = model.id ?? UUID().uuidString
}
required init(id: String) {
var model = T.init()
model.id = id
self.model = model
self.id = id
}
init(model: T) {
self.model = model
self.id = model.id ?? UUID().uuidString
}
static func ==(lhs: BaseViewModel<T>, rhs: BaseViewModel<T>) -> Bool {
lhs.model.id == rhs.model.id
}
func load(completion: #escaping (Bool) -> Void = {finished in}){
if let id = model.id {
self.id = id
db.collection(model.collection).document(id).getDocument { docSnapshot, error in
guard let doc = docSnapshot else {
print("Error fetching document: \(error!)")
return
}
do {
guard let data = try doc.data(as: T.self) else {
print("Document empty \(type(of: self.model)) with id \(id)")
return
}
self.model = data
self.loadSubData {finished in
if finished{
completion(true)
}
}
} catch {
print(error.localizedDescription)
}
}
}
}
func loadSubData(completion: #escaping(Bool) -> Void = {finished in}) {
fatalError("Must be overridden!")
}
func loadDataByIDs<T, S>(from list: [String], appender: #escaping (T) -> Void) where T: BaseViewModel<S>, S: BaseModel {
for id in list {
let viewModel = T.init(id: id)
viewModel.load{finished in
if finished {
appender(viewModel)
}
}
}
}
func save(){
do {
let _ = try db.collection(model.collection).addDocument(from: model)
} catch {
print(error)
}
}
func update(){
if let id = model.id {
do {
try db.collection(model.collection).document(id).setData(from: model)
} catch {
print(error.localizedDescription)
}
}
}
func delete(){
if let id = model.id {
db.collection(model.collection).document(id).delete() { error in
if let error = error {
print(error.localizedDescription)
}
}
}
}
}
I had the same problem, I am solved it after I updated Quick/Nimble.
I guess some pod project with x86 files meed to update to support M1
Well for the record, anybody who is experiencing these odd bugs on M1 must read exactly inside the excode compilation error.
If they are saying a specific class it means xcode can't compile your code and you should just remove the code and try to compile line by line.
I know that's very strange, looks like programming PHP and refreshing a webpage but I'm sure this type of bug can be related to the platform migration.
In my situation, I had a class that was OK, I started refactoring and instead of xcode showing me the compilation errors, it gave this cryptic BPT5, at reading exactly the description inside of the IDE I could find that my class was the root cause.
Just remove the code all over you changed and try to compile it again...
Sorry for the late update on that. But in my case it was either CocoaPods in general or the Firebase Pods, which were not compatible with Apple Silicon at that time.
I was just using Swift Package Manager and with that, it worked.
I do not know though, if the problem still exists, because I didn't build another app on the M1 MacBook.
I run into this issue after I accidently extract a view as variable without awareness. You shall check your recently committed code to figure it out.
I have a problem with a FireStore, hope some of you could help me.
I'm trying to create a document this way:
class FireStoreUtils: NSObject {
static let defaultUtils = FireStoreUtils()
var db = Firestore.firestore()
var fireStoreSettings = FirestoreSettings.init()
override init() {
super.init()
fireStoreSettings.host = FireStoreParameters.host
fireStoreSettings.isSSLEnabled = FireStoreParameters.sslEnabled
fireStoreSettings.isPersistenceEnabled = FireStoreParameters.persistenceEnabled
fireStoreSettings.cacheSizeBytes = Int64(FireStoreParameters.cacheSizeBytes)
db.settings = fireStoreSettings
}
weak var delegate:FireStoreUtilsDelegate?
func addNewUser(userData userDictionary: [String: Any],userId uId: String) {
do {
let table = self.db.collection("Collection_name")
let documentRef = table.document(uId)
try? documentRef.setData(userDictionary, completion: { (error) in
if (error != nil) {
self.delegate?.didFailToPerformOperation(errorMessage: error?.localizedDescription)
}
else {
self.delegate?.didSucceedToPerformOperation(message: "Success")
}
})
}
catch let error {
self.delegate?.didFailToPerformOperation(errorMessage: error.localizedDescription)
}
}
But from some reason executing setData I get the following crash
assertion failed: 0 == pthread_setspecific(tls->key, (void)value)*
I tried to use FireStore logs but the last log message I got is
2021-01-17 18:55:12.114707+0200 7.3.0 - [Firebase/Firestore][I-FST000001] Creating Firestore stub.
I added Firestore manually and din't use nor Swift PM or Pods, because both of the didn't work with FirebaseAuth in pod file.
It starts to look like everything is dead end.
If somebody knows what's going on or got similar problem, please,help!
Thank you,
Maria.
So, I have a program that, when it opens, looks for a specific document name in a specific collection (both specified) and, when it is found, copies the document name and starts a listener. If it doesn't find the document name after 5 x 5 second intervals, the app stops. For some reason, when I run the code, after it does the first check I get about a thousand writes of this error:
[Firebase/Firestore][I-FST000001] WriteStream (7ffcbec0eac8) Stream error: 'Not found: No document to update:
Here's the code I'm using to call firestore:
let capturedCode: String? = "party"
.onAppear(perform: {
Timer.scheduledTimer(withTimeInterval: 5, repeats: true) { timer in
print("running code check sequence")
if let code = capturedCode {
calcCloud.checkSessionCode(code)
if env.doesCodeExist {
print("code found! applying to environment!")
env.currentSessionCode = code
calcCloud.watchCloudDataAndUpdate()
allClear(env: env)
timer.invalidate()
}
else if timerCycles < 5 {
timerCycles += 1
print("code not found, this is cycle \(timerCycles) of 5")
} else {
print("could not find document on firebase, now committing suicide")
let x = ""
let _ = Int(x)!
}
}
}
})
here is the code I'm using to check firebase:
func checkSessionCode(_ code: String) {
print("checkSessionCode running")
let docRef = self.env.db.collection(K.sessions).document(code)
docRef.getDocument { (document, error) in
if document!.exists {
print("Document data: \(document!.data())")
self.env.doesCodeExist = true
} else {
print("Document does not exist")
self.env.doesCodeExist = false
}
}
}
and here is the code that should be executed if the code is found and applied:
func watchCloudDataAndUpdate() {
env.db.collection(K.sessions).document(env.currentSessionCode!).addSnapshotListener { (documentSnapshot, error) in
guard let document = documentSnapshot else {
print("Error fetching snapshot: \(error!)")
return
}
guard let data = document.data() else {
print("Document data was empty.")
return
}
Where did I go wrong, and what is this error all about...thanks in advance :)
EDIT: For clarity, it seems that the errors begin once the onAppear finishes executing...
This is why I need to stop coding after 1am...on my simulator, I deleted my app and relaunched and everything started working again...sometimes the simplest answers are the right ones...
I have a command line app that does the following:
downloads an RSS feed with torrent links
stores it in a sqlite database and tags them as "added" or "ignored"
connects to a transmission server (in my local network)
loads items from sqlite marked as "added" and adds to transmission server
The above works fine in debug mode. However, when I build for release and try to run directly or from launchd, it always times out. The most relevant code is in main.swift which goes below.
private func getTransmissionClient() -> Transmission? {
let client = Transmission(
baseURL: serverConfig.server,
username: serverConfig.username,
password: serverConfig.password)
var cancellables = Set<AnyCancellable>()
let group = DispatchGroup()
group.enter()
print("[INFO] Connecting to client")
client.request(.rpcVersion)
.sink(
receiveCompletion: { _ in group.leave() },
receiveValue: { rpcVersion in
print("[INFO]: Successfully Connected! RPC Version: \(rpcVersion)")
})
.store(in: &cancellables)
let wallTimeout = DispatchWallTime.now() +
DispatchTimeInterval.seconds(serverConfig.secondsTimeout ?? 15)
let res = group.wait(wallTimeout: wallTimeout)
if res == DispatchTimeoutResult.success {
return client
} else {
return nil
}
}
public func updateTransmission() throws {
print("[INFO] [\(Date())] Starting Transmission Update")
let clientOpt = getTransmissionClient()
guard let client = clientOpt else {
print("[ERROR] Failed to connect to transmission client")
exit(1)
}
var cancellables = Set<AnyCancellable>()
let items = try store.getPendingDownload()
print("[INFO] [\(Date())] Adding \(items.count) new items to transmission")
let group = DispatchGroup()
for item in items {
let linkComponents = "\(item.link)".components(separatedBy: "&")
assert(linkComponents.count > 0, "Link seems wrong")
group.enter()
client.request(.add(url: item.link))
.sink(receiveCompletion: { completion in
if case let .failure(error) = completion {
print("[Failure] \(item.title)")
print("[Failure] Details: \(error)")
}
group.leave()
}, receiveValue: { _ in
print("[Success] \(item.title)")
do {
try self.store.update(item: item, with: .downloaded)
} catch {
print("[Error] Couldn't save new status to DB")
}
})
.store(in: &cancellables)
}
let wallTimeout = DispatchWallTime.now() +
DispatchTimeInterval.seconds(serverConfig.secondsTimeout ?? 15)
let res = group.wait(wallTimeout: wallTimeout)
if res == DispatchTimeoutResult.success {
print("Tasks successfully submitted")
} else {
print("Timed out")
exit(1)
}
}
Oddly enough, the code seemed to work fine before I added the database. The DispatchGroup was already there, as well as the Transmission-Swift client. I guess something that I did is being "optimized away" by the compiler? This is just speculation though after seeing some other questions on StackOverflow, but I am still not clear on it.
I am using macOS 10.15 and Swift 5.2.2.
Full code available in github (link to specific commit that has the bug)
I asked for help on Swift Forums at https://forums.swift.org/t/not-connecting-to-rpc-server-in-release-mode-but-works-fine-in-debug-mode/36251 and here is the gist of it:
Debug vs Release bugs are common in the Apple ecosystem.
One common reason for the above: the compiler has much more aggressive retain and release patterns in release mode.
My problem was exactly that: a certain class was being disposed of earlier than it should and it was exactly the cancellable for the subscription, so my server requests were being cancelled in the middle.
This commit fixes it and it basically does the following:
diff --git a/Sources/TorrentRSS/TorrentRSS.swift b/Sources/TorrentRSS/TorrentRSS.swift
index 17e1a6b..0b80cd5 100644
--- a/Sources/TorrentRSS/TorrentRSS.swift
+++ b/Sources/TorrentRSS/TorrentRSS.swift
## -63,6 +63,10 ## public struct TorrentRSS {
DispatchTimeInterval.seconds(serverConfig.secondsTimeout ?? 15)
let res = group.wait(wallTimeout: wallTimeout)
+ for cancellable in cancellables {
+ cancellable.cancel()
+ }
+
if res == DispatchTimeoutResult.success {
return client
} else {
## -117,6 +121,11 ## public struct TorrentRSS {
let wallTimeout = DispatchWallTime.now() +
DispatchTimeInterval.seconds(serverConfig.secondsTimeout ?? 15)
let res = group.wait(wallTimeout: wallTimeout)
+
+ for cancellable in cancellables {
+ cancellable.cancel()
+ }
+
if res == DispatchTimeoutResult.success {
print("Tasks successfully submitted")
} else {
Calling cancellable explicitly avoids the object being disposed of before it should. That specific location is where I meant to dispose of the object, not any sooner.
I'm looking for a way to get a list of groups (CNGroup) that relate to a contact container (CNContainer). When I use a predicate it fails.
The code I'm using is
func populateGroups(tableView:NSTableView,container:CNContainer){
print("populateGroups.start")
print(container.name)
print(container.identifier)
let contactStore = CNContactStore()
do {
let groupsPredicate = CNGroup.predicateForGroups(withIdentifiers: [container.identifier])
groups = try contactStore.groups(matching: groupsPredicate)
groupNames.removeAll();
for group:CNGroup in groups {
self.groupNames.append(group.name)
}
tableView.reloadData()
} catch {
print( "Unexpected error fetching groups")
}
print("populateGroups.finish")
}
I'm getting an error from that doesn't make sense to me.
The line groups = try contactStore.groups(matching: groupsPredicate) causes an error.
[Accounts] Failed to update account with identifier 47008233-A663-4A52-8487-9D7505847E29, error: Error Domain=ABAddressBookErrorDomain Code=1002 "(null)"
Which is confusing as I'm not updating any account.
If I change that line of code to groups = try contactStore.groups(matching: nil)
I get all the groups for all the containers.
How do you create a predicate that will return all the CNGroups that belong to a CNContactContainer?
I worked around this by checking that each group from all the groups belonged to the container in question using CNContainer.predicateForContainerOfGroup
func populateGroups(tableView:NSTableView,container:CNContainer){
let contactStore = CNContactStore()
do {
let groups:[CNGroup] = try contactStore.groups(matching: nil)
self.groups.removeAll();
groupNames.removeAll();
for group:CNGroup in groups {
let groupContainerPredicate:NSPredicate = CNContainer.predicateForContainerOfGroup(withIdentifier: group.identifier)
let groupContainer:[CNContainer] = try contactStore.containers(matching: groupContainerPredicate)
if( groupContainer[0].identifier == container.identifier) {
self.groupNames.append(group.name)
self.groups.append(group)
}
}
tableView.reloadData()
} catch {
print( "Unexpected error fetching groups")
}
}
