Swift framework localization
I am trying to localize Swift framework and added a file Localizable.Strings and that file is included in the target but the app that consumes this framework is showing the key not the actual string. NSLocalizedString("string_key", comment: "Actual String") I think issue is related to bundle. Do I need to add bundle parameter to NSLocalizedString? If so what is the bundle parameter value? If bundle is not required then what must be the issue

Passing delegate/protocol as function parameter
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.

Semaphore
class  a {     b().download ({ data in     }) } class  b{     func download (downloadedData: @escaping (_ data: Data? ) -> Void )  {         c().download()     } } class c {     func download () -> Data {         let semaphore = DispatchSemaphore(value: 0)           NetworkManager().downloadRequest: { (result: Result<Data, Error>) in                                             switch result {                                             case .success(let success)                                                 ......                                              case .failure(let error): .....                                             }                                             semaphore.signal()                                    }                         )         semaphore.wait()         return data     } } Class a initiates the download and class c interacts with network manager to download the data. Class c issues semaphore wait as soon as it sends request to download the data and issues signal when download completes. Is there a way to issue signal from class a when download is in progress. Basically class a should be able to skip wait by issuing signal command

Data from Swift Enum to SwiftUI
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

Pass Data from Swift to SwifUI
I developed a framework in Swift and designed a screen/view via SwiftUI. SwiftUI view will be presented on top of the Window by the class written in Swift. Now I need to pass the data from the Swift class to SwiftUI. Could one any help to know the best practice to pass the data to show the progress from Swift class to Swift UI. func A () {} func B () { // score will get updated frequently score = .... ScorePresenter().presentScoreUI() } } import SwiftUI struct ScorePresenter: { func presentScoreUI() { let hostController = UIHostingController(rootView: ScoreUI()) hostController = .overCurrentContext topViewController()!.present(hostController, animated: true, completion: nil) } } struct ScoreUI: View { var score = 1 Text(score).foregroundColor(.green) } When ever score changes in Score class ScoreUI must be updated accordingly.

Decoding Downloaded Data
I know that using using JSONDecoder we can convert the downloaded JSON data into class/struct object. Is there a way to do the same for raw data(NSData)/octect. Since downloaded is not a json, I am getting error. I have class like this public struct FileData: Codable{ public var data: Data? public init (data: Data? = nil){ self.data = data } } Is there a way to assign the downloaded data to FileData().data via decoding

Swift package manager
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.
