Hello folks! I stumbled upon a curious problem. After adding xcframework Web RTC from here my app starts to crash on one of the clients' mac mini with Catalina. What is strange, on identical hardware with the same macOS other clients don't have problems. Below I attached crash logs. What should I do? I haven't got any more ideas, I've tried in many ways, but nothing helped. Any tips? Thanks in advance!

Hello guys, I made some research about the above title and I am still not satisfied. My team requires app obfuscation, we know solutions such as DexProtector, but we aren't sure of no one of them. We have a simple macOS app that uses our custom framework. The app could be unobfuscated, but the framework keeps secret hardcoded etc., and it requires that. How do you think, what solution should we use and why? Which one is most secure, from your experience? And how secure is the macOS signed app natively, without additional protection? Thanks in advance!

Hello there, I stumbled on the issue of observing UserDefaults. My need is to "listening"/observing UD key named "com.apple.configuration.managed" which is responsible for reading provided MDM external plist. I checked that on the opened app it is possible to provide that plist, and app read this payload correctly. My problem is to observing that change, when plist is uploading. Requirement is to support iOS 13, this is why I can't use AppStorage. Despite using some similar solutions like: someone own implementation of AppStorage, and using StackOverflow solutions like this, it still doesn't work. My, I feel, the closest one solution was:   @objc dynamic var mdmConfiguration: Dictionary<String, String> {     get { (dictionary(forKey: MDM.ConfigurationPayloadKey) != nil) ? dictionary(forKey: MDM.ConfigurationPayloadKey)! as! Dictionary<String, String> : Dictionary<String, String>() }     set { setValue(newValue, forKey: MDM.ConfigurationPayloadKey)}   } } class MDMConfiguration: ObservableObject {       //@Binding private var bindedValue: Bool       @Published var configuration: Dictionary = UserDefaults.standard.mdmConfiguration {     didSet {       UserDefaults.standard.mdmConfiguration = configuration     //  bindedValue.toggle()     }   }   private var cancelable: AnyCancellable?   init() {  // init(toggle: Binding<Bool>) {     //_bindedValue = toggle     cancelable = UserDefaults.standard.publisher(for: \.mdmConfiguration)       .sink(receiveValue: { [weak self] newValue in         guard let self = self else { return }         if newValue != self.configuration { // avoid cycling !!           self.configuration = newValue         }       })   } } struct ContentView: View {       @State private var isConfigurationAvailable: Bool = false   @State private var showLoadingIndicator: Bool = true   @ObservedObject var configuration = MDMConfiguration()       var body: some View {           GeometryReader { geometry in               let width = geometry.size.width       let height = geometry.size.height                             VStack {         Text("CONTENT -> \(configuration.configuration.debugDescription)").padding()         Spacer()         if !configuration.configuration.isEmpty {           Text("AVAILABLE").padding()         } else {           Text("NIL NULL ZERO EMPTY")             .padding()         }       }        }   } } But it still doesn't ensure any changes in view, when I manually click on f.e. button, which prints the configuration in the console when it has uploaded, it does it well. Please help, my headache is reaching the zenith. I am a newbie in Swift development, maybe I did something weird and stupid. I hope so :D Thank in advance!
