I have been exploring different options to integrate 3D shapes, objects with my app. I came across this starter-friendly 3D creation platform Spline, and it helps generate public URL, .gitf for the 3D objects. Is there anyway that I can have the objects in my app using SwiftUI while keeping all the features?

I am trying to get integer input by using textfield. However, I noticed that if I changed the binding variable as optional with an initial value of null, the textfield would not work. I would like to keep it as null initially because I want the placeholder to show text before the input, and if the int variable starts with any valid value, the text would not be shown. Is there a way to fix things here? struct TextFieldNumberInputView: View {     @Binding var intVariable: Int?     @State var isEditing: Bool = false     @State var placeholderText: String     @State var number: Int = 0          var body: some View {         VStack(alignment: .leading, spacing: 2){             TextField(placeholderText, value: $number, formatter: NumberFormatter()){             }             .textFieldStyle(InputTextFieldStyle())             .keyboardType(.numberPad)             .onReceive(Just(number)) {_ in                 print("number pad being editing")                 if isEditing == false && intVariable != nil {                                         isEditing = true                     print("number is being edited")                 } else if isEditing == true && intVariable != nil{                     isEditing = false                 }             }                          Text(placeholderText)                 .font(.caption2)                 .foregroundColor(isEditing ? Color(.systemGray3):Color.clear)                 .padding(.horizontal)                 .padding(.horizontal, 12)                  }.onTapGesture {             print("number pad being tapped, intVariable \(intVariable), \(number)")                          if number != nil {                 print("checking number")                 UIApplication.shared.sendAction(#selector(UIResponder.resignFirstResponder), to:nil, from:nil, for:nil)             }                      }     }      }

I am using SwiftUI, and I am trying to use share sheet to share image from my app to other apps. I found that my image could send to every native app in iPhone such as message, email and the image could be saved to local picture app, but for any other app, it would have a sort of buggy response, like WeChat, WhatsApp. When I chose to share the image in these apps, I could tell that there was a screen popping up but the screen would not be shown fully, leaving a transparent background. And they just freeze there.

I have been developped this app for almost three years. It worked perfectly fine till I changed my phone to iPhone 16 and upgraded my xcode to the latest version (Version 16.0 (16A242d)). After the app finish building, the app will crash automatically when open. I had this onboarding page to be presented at the very beginning, simple image with an action button. The app kept breaking, and I found the Thread indicating error with ActionLabelView (Thread 1: EXC_BAD_ACCESS (code=2, address=0x16d107fa0)). I commented out the button on my app's onboarding page once, the app could run but to the next step will need the button. The code should be fine I believe, cuz nothing like this ever came up with my old phone and old xcode version. Could some one please help?

I recently bought a new phone and update xcode version to the latest. An app that I have been developing and worked perfectly fine would not be runned. I kept getting errors similar to below. Is that anything wrong with my setting or something? Class _TtC6SQLite6Backup is implemented in both /System/Library/PrivateFrameworks/LinkServices.framework/LinkServices (0x1f16db218) and /private/var/containers/Bundle/Application/E2xxxx2xxA-DF7B-xx-***-xxxxxxxx/xxxx.app/xxxxx.debug.dylib (0xxxxxx3d0). One of the two will be used. Which one is undefined.
