Xcode is not responding when opening a workspace. I deleted the cache, derived data, saved application state and xcuserdata. I tried with different Xcode version too. Any help is much appreciated.

I have a framework written in Objective-C. My framework is in Swift and imported the 3rd party Objective-C framework in my project. @interface AAAA: NSObject(void)setHandler:(idHandler)handler @end I wanted to implement the Handler protocol in my Swift project. I did like this Class ZXY: NSObject, Handler{ init(){ super.init AAAA.setHandler(self) } // Implemented Handler Protocol optional methods func aaaa(){ } } Handler protocol optional method aaaa never called. Am I missing anything

I am using "Excluded Source File Names" in Xcode build settings to remove a folder from IPA. The given relative path is correct but for some reason, the folder that needs to be excluded is still exists in the .app file. Any idea why Excluded Source File Names is not working. The folder that I am trying to remove is listed under "Copy Bundle Resources" Here is the path "$(SRCROOT)/../foldera/folderb/foldertoberemoved"

My client is using Xcode 11 but the iOS framework imported in the project is available only in Xcode 13. Client is getting "framework not found" in Xcode 11 . Is there a way to make my project compatible with older Xcode Version?

I have an Xcode project that generates xyz.framework and that framework is used by other teams for their app. Updating the framework is a manual process. So I am planning to covert my xyz.framwork source to swift package manager. I couldn't find any such articles. Please let me know if there is any resource around this topic.

I am getting an error message (mixed language) while adding the Swift package dependency. Source code mostly contains Swift language and a little bit of Objective-C. Can't we mix Swift and Objective-C language? If so, what is the workaround

DispatchQueue.main.asyncAfter(deadline: .now() + 10) { //code } code within asyncAfter will get executed after 10 seconds. Is there a way to cancel execution before 10 seconds

I have a framework that will be consumed by other developers to develop the app. I designed a view using SwiftUI in that framework and wanted to present that view with model animation programatically from the framework. There are many sample that shows how to present a view with modal animation associated with button tap. Can anyone let me know how to present a view modal programmatically?

I have a framework written in Swift and I wanted to design a view using SwiftUI. Is it possible?

I have a class written in Swift that will present the view developed using SwiftUI. SwiftUI is dependent on the enum used in Swift class to render the UI. Is there a way to bind that enum in Swift UI so that SwiftUI will update automatically when ever there is a change to the enum in Swift class

public protocol UploadDelegate: AnyObject {} class NetworkManager: UploadDelegate {} class A { B().abc(uploadDelegate:NetworkManager() ) } class B { func abc (uploadDelegate: UploadDelegate) { C().efg(uploadDelegate:uploadDelegate ) } } class C { func efg (uploadDelegate: UploadDelegate) { D().hij(uploadDelegate:uploadDelegate ) } } class D { func hij (uploadDelegate: UploadDelegate) { uploadDelegate.func() } } Can we pass the protocol/delegate as a func parameter? If yes, I believe its a weak property.

class A { func processData { let viewModel: ViewModal = ViewModal() let viewController = ViewController() viewController.displayUI(viewModel) .... .... .... .... viewModel.imageName = "abcd" .... .... .... .... viewModel.imageName = "efg" .... .... .... .... viewModel.imageName = "hij" } } class ViewController { func displayUI (viewModal: ViewModal){ let contentView = ContentView(viewModal: viewModal).environmentObject(self) // present contentView } } class ViewModal { @Published var imageName: String = ""   @Published var label: String = "" // string formatting } struct ContentView: View {  @State var viewModel: ViewModal  @EnvironmentObject var viewController: ViewController  var body: some View { } } Can class A directly access ViewModal or it should pass the data to ViewController and ViewController set the data in ViewModal

func displayUI () { let hostingController = UIHostingController(rootView: ContentView(ViewModel: contentViewModal).environmentObject(self)) } Above code works fine. I attempted to make the hostingController as instance variable instead of local variable and declared the hostingController outside of display function like this lazy var hostingController: UIHostingController = UIHostingController(rootView: ContentView()) and so I removed let keyword func displayUI () {  hostingController = UIHostingController(rootView: ContentView(ViewModel: contentViewModal).environmentObject(self)) } Once I remove the let keyword I started getting this error. Cannot convert value of type 'some View' to specified type ‘ContentView' Any idea why I am getting this error after removing let keyword declared before hostingController variable?

I wrote a few unit test cases using XCTest by mocking the data? Is there any best practice to have multiple test profiles with different data sets? Sometime mock should return nil, sometimes an array with 2 elements and sometimes an array with 10 elements. How to have multiple test profiles?

Is there a way to mock the CBPeripheral? I need to stub the CBPeripheral(name & identifier) data in Xcode.
