Ios swift – NSException occures while setuping Tuya SDK on IOS

I am new on IOS development and I am trying to create lot app using Tuya Smart Life App SDK. I am facing problem when I try to start the app after adding this SDK configure, with appKey and appSecret:

ThingSmartSDK.sharedInstance()?.start(withAppKey: <#your_app_key#>, secretKey: <#your_secret_key#>)

According to the Fast Integration guide this should be placed inside of AppDelegate.m -file, but I have read that this file is not being added to IOS projects automatically any more. (I am using Xcode version ‘14.3.1’)

I have added the AppDelegate class inside of AppNameApp.swift -file and it looks like this:

import SwiftUI
import ThingSmartBaseKit

@main
struct AppNameApp: App {
    
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        ThingSmartSDK.sharedInstance().start(withAppKey: <#your_app_key#>, secretKey: <#your_secret_key#>)
        
        #if DEBUG
        ThingSmartSDK.sharedInstance().debugMode = true
        #else
        #endif
        
        
        return true
    }
}

Currently I am not seeing any problem messages coming from this in Xcode, but when I try to run the app on simulator it crashes due to uncaught exception of type NSException. Crash message:

    After fighting for some time over this I found the solution.

    The app needs to be run as Rosetta simulator to get it to run without crash.

    There was also a problem with ContentView canvas not showing a preview, but I manage to fix this problem by setting Automatically Refresh Canvas off (Editor -> Canvas -> Automatically Refresh Canvas (uncheck this if its checked)).

    This error indicates that there are ObjC categories that are not being loaded. See Technical Q&A QA1490 for full details. You need to include the -ObjC flag in Other Linker Flags. I would expect this to have been done by the CocoaPod if you’re using it, however. I would discuss this with Tuya if you’ve followed their instructions.
