How to fix Sparkle Unable to check for Updates

I'm trying to setup an auto-update feature using Sparkle in my Mac app using SwiftUI. I keep getting an Unable to check for Updates error. Updae Error Image

I wasn't able to figure out how to fix it based on the documentation and I've not tried to set anything like this up before.

I'm not sure if I messed something up in my swift code or if my .xml file has an error. Or maybe something else. I've attached some of my code below.

Swift file:

final class CheckForUpdatesViewModel: ObservableObject {
    @Published var canCheckForUpdates = false
    
    init(updater: SPUUpdater) {
        updater.publisher(for: \.canCheckForUpdates)
            .assign(to: &$canCheckForUpdates)
    }
}

struct CheckForUpdatesView: View {
    @ObservedObject private var checkForUpdatesViewModel: CheckForUpdatesViewModel
    private let updater: SPUUpdater
    
    init(updater: SPUUpdater) {
        self.updater = updater
        
        // Create our view model for our CheckForUpdatesView
        self.checkForUpdatesViewModel = CheckForUpdatesViewModel(updater: updater)
    }
    
    var body: some View {
        Button("Check for Updates…", action: updater.checkForUpdates)
            .disabled(!checkForUpdatesViewModel.canCheckForUpdates)
    }
}

xml file:

func isUpdateAvailable() throws -> Bool {
    guard let info = Bundle.main.infoDictionary,
        let currentVersion = info["CFBundleShortVersionString"] as? String,
        let identifier = info["CFBundleIdentifier"] as? String,
        let url = URL(string: "https://itunes.apple.com/lookup?bundleId=\(identifier)") else {
        throw VersionError.invalidBundleInfo
    }
    let data = try Data(contentsOf: url)
    guard let json = try JSONSerialization.jsonObject(with: data, options: [.allowFragments]) as? [String: Any] else {
        throw VersionError.invalidResponse
    }
    if let result = (json["results"] as? [Any])?.first as? [String: Any], let version = result["version"] as? String {
        return version != currentVersion
    }
    throw VersionError.invalidResponse
}

enum VersionError: Error {
    case invalidResponse, invalidBundleInfo
}

DispatchQueue.global().async {
    do {
        let update = try self.isUpdateAvailable()
        DispatchQueue.main.async {
            // show alert
        }
    } catch {
        print(error)
    }
}

try using this method works better , no need to use sparkle pod
