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): https://pastebin.com/MiSKGxB7 (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)
}
}
}
}
}
