Hello Team we facing a problem with a UIView inside of a Navigation Bar what we need to achieve is to place a UIView (SwiftUI Wrapper) on the middle of the Navigation bar Here's how it looks like right now that's already complete, but now the problem that we are facing is that the View is not detecting the clicks/taps on the 'dates and 'travelers' here's the Code for the View private lazy var sharedUIPlaybackView: UIView = { let containerView = UIView().withAutoLayout() containerView.backgroundColor = .red containerView.styleBorder(color: .systemPink, width: 1) let propertySearchCriteria = PropertySearchCriteriaBuilder(hotelSearchParameters: viewModel.hotelSearchParameters).criteria var swiftUIView: SwiftUIView<LodgingPlaybackWrapper>! = nil swiftUIView = SwiftUIView( LodgingPlaybackWrapper(propertySearchCriteria: propertySearchCriteria, playbackUpdateNotificationSender: nil, componentHandler: { [weak self] componentId in self?.componentReady(componentId) }), viewDidLayoutSubviewsCallback: { [weak self] in let newHeight = swiftUIView.frame.size.height if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant { self?.sharedUIPlaybackViewHeightConstraint?.constant = newHeight self?.additionalSafeAreaInsets.top = 200 } } ).withAutoLayout().withAccessibilityIdentifier("searchPlayback") sharedUIPlaybackViewHeightConstraint = containerView.heightAnchor.constraint(equalToConstant: 0) sharedUIPlaybackViewHeightConstraint?.isActive = true swiftUIView.backgroundColor = .blue swiftUIView.styleBorder(color: .orange, width: 1) containerView.addSubview(swiftUIView) containerView.addConstraints([ swiftUIView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: Spacing.spacing4x), swiftUIView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -Spacing.spacing4x) ]) self.view.bringSubviewToFront(swiftUIView) swiftUIView.isUserInteractionEnabled = true swiftUIView.layer.zPosition = 1 return containerView }() my first suspicion was that the this part of the code was not expanding correctly viewDidLayoutSubviewsCallback: { [weak self] in let newHeight = swiftUIView.frame.size.height if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant { self?.sharedUIPlaybackViewHeightConstraint?.constant = newHeight self?.additionalSafeAreaInsets.top = 200 } } but after I place border and background colors on the views was clear for me that it was expanding properly, so I added some modifiers for the view like swiftUIView.isUserInteractionEnabled = true swiftUIView.layer.zPosition = 1 but didn't work, I'm asking for a solution and different point of view for the code to be more cleaner and do the best implementation posible. This Navigation bar should be treated as a custom Navigation Bar, or it is good for us to expand and treat the Navigation bar like this? (expanding and adding a Custom View) thanks in advance to anyone who read this. here's the View Hierarchy

I notice that this operation is expensive for the code (2^set.size). I'm looking the best practices and implementations more likely a re-work this code goes to a infinite bucle and freezes the app until it's done func generateSubsets(set: Set<String>) -> Set<Set<String>> { if set.count == 1 { return [set] } let first = set.map { item -> Set<String> in var clone = set clone.remove(item) return clone } let second = first.map(generateSubsets) var subSets = second.reduce(Set<Set<String>>()) { accumulator, elements in var clone = accumulator for element in elements { clone.insert(element) } return clone } subSets.insert(set) return subSets } Example For input ["qual1", "qual2", 'qual3"] the combinations can be: ["qual1#qual2#qual3", "qual1#qual2", "qual1#qual3", "qual2#qual3", "qual1", "qual2", "qual3"]

Hey guys I'm having some struggles when trying to understand how to edit certain section for a viewForFooterInSection note the edit occurs when the user types something and this function gets call, that is already managed override func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? { return prepareFooterView(tableView: tableView, section: section) } the question is how can I access certain section for me to edit the title on it? the function for footherview is: func prepareFooterView(tableView: UITableView, section: Int) -> UIView?{ guard let tableView = tableView as? LightTableView else { return UIView() } guard section <= TableSection.all.count else { return UIView() } ///the section is obtained here let section = TableSection.all[section] var title = "" switch section { case .detailsFooterView: title = "card_details_section_footer".localized case .nickname: if nickname?.isValidNickName == false { return prepareSpecificMessageInFooterView(with: "card_nickname_section_footer_error".localized, errorMessage: true) } title = "card_nickname_section_footer".localized case .fastlink: title = "earn_rewards_section_footer".localized default: title = "" } var footerView = tableView.standardFooterView(withTitle: title, textAlignment: .left, accessibilityIdentifier: section == .nickname || section == .fastlink || section == .detailsFooterView ? "NicknameFooterViewID" : nil, labelPadding: UIEdgeInsets(top: 12, left: 16, bottom: 0, right: -16)) return section == .nickname || section == .fastlink || section == .detailsFooterView ? footerView : nil } I would like to edit the case .fastlink: when a flag is turned ON the section here: num TableSection: Int { case details case detailsFooterView case nickname case fastlink case scan static var all: [TableSection] = isUs ? [.details, .detailsFooterView, .nickname, .fastlink] : [.details, .detailsFooterView, .nickname, .fastlink, .scan] } I guess this is not clear for me because this is running live instead of reloading the entire screen for example indexPath.row == 1

Hey Developers I'm facing some strange situation, I'm getting multiples issues related to optimization on Release build configuration, I'm using Xcode 13.2.1 project is separated in 4 markets and multiples frameworks none of the markets have dependencies from each other, issue only appears when the market RefrreshAtPumpAUS Release is build, on the other side for Debug everything is functional and the app build fine. here's my Podfile: Podfile in order to add the : def adobe_manager_pods into the framework: CoolMasterUtilsFramework as the project is in 4 different markets had to added in the different markets like this:    target 'RefrreshAtPumpNL' do           # Pods for RefrreshAtPump     common_pods     adobe_manager_pods --> here       target 'RefrreshAtPumpUS' do        # Pods for RefrreshAtPump    common_pods    firebase_pods    adobe_campaign_pods    adobe_manager_pods. --> here       target 'RefrreshAtPumpUK' do             # Pods for RefrreshAtPump    common_pods    adobe_manager_pods --> here but for the AUS market(RefrreshAtPumpAUS) is quite different already had added similar PODS   target 'RefrreshAtPumpAUS' do        # Pods for RefrreshAtPump    common_pods    firebase_pods    adobe_experience_pods. ->> here they have this so, I added the 2 remaining that I needed for that specific market.   def adobe_experience_pods    pod 'AEPAudience', '~> 3.0’ ------->> THIS ONE    pod 'ACPUserProfile', '~> 2.2’ ------->> THIS ONE    pod 'AEPEdgeIdentity', '~> 1.0'    pod 'AEPEdgeConsent', '~> 1.0'    pod 'AEPCore', '~> 3.0'    pod 'AEPIdentity', '~> 3.0'    pod 'AEPSignal', '~>3.0'    pod 'AEPLifecycle', '~>3.0'    pod 'AEPUserProfile', '~> 3.0'    pod 'AEPEdge', '~> 1.0'    pod 'AEPMessaging', '~> 1.0'    pod 'AEPAssurance', '~> 3.0', :configurations => ['Debug']   end so if I run the project in all other markets as RELEASE or DEBUG everything goes well, but only for RELEASE on RefrreshAtPumpAUS shows errors like this:  multiple errors I've tried adding lines inside the RefrreshAtPumpAUS like this: 1.- post_install do |installer| 2.- Pod update 3.- delete all Derived data 4.- in Build settings -> Apple Clang - Code generation -> Optimization level to None[-O0] 5.- in Build settings -> Build active architecture only -> ALL to YES 6.- in podfile -> delete this line use_frameworks! and adding use_modular_headers!  7.- in Build settings -> Swift compiler -> Code generation -> Incremental to all Error 1

I am trying to get a UITableView with a UICollectionView to show the following data set correctly inside the UICollectionViews. the array which contains all this information is arregloDeArreglos here's the data - some : 1 [![dads][1]][1] However, when I scroll horizontally inside the UICollectionViews, the data will get all messed up. [1]: https:// i.stack. imgur. com/z9bw7 . png [2]: https://i. stack. imgur.com/lCS13 . png as you can see in both pictures here's my code table delegate and data source } uicollection delegate and datasource } uiCollectionviewCell }

Hi, im struggle with my cell model it's only showing my array position 0 what i'm trying to reach is show in each UICollectionView the information inside arregloBidimencional which contains let episodes: [episodess]? and let tack: Int? episodess is my main struct for the didSet inside each UICollectionviewCell and tack is my identifier for each array of [episodess] } var arraySeasonsEpisodes: [episodess] = [] its type of episodess so my model to get the previous data is } so the didset in UICollectionViewCell it's set like this } this is how i storage the data from the json dictionary }

Hi, i'm having this issue using Xcode 12.2 were i can't scroll in horizontal direction a UICollectionView, i have try multiples answers from the forum and none of then work for me first of all what i'm only trying to achieve is the scroll horizontally. Heres my UITableView declaration on the View: }() here's the Delegate and DataSource protocols in VC: } This is the code for UICollectionView declaration on the NumberOfSeasonsCell or UITableViewCell }() Protocols for the UICollectionView } i've read that i should store the last position of the Table for scrolling the UICollectionView but i've tried but not work for me here's the UICollectionViewCell }

Hi developers im having this trouble with expandable cells sections when using return arrayUiText[section].nombre.count on numberOfRowsInSection, only returns 1 cell and that's correct because it only have 1 number in the array, but my question is how could i return more than one because i have 3 different cells but returning is been a struggle for me as you can see my arrayUiText as multiples names in diffent arrays, i could archieve my goal just adding multiples names on 1 array, but i could only use 1 SectionHeader and that's not what i wanted to do nombre: ["dasdad dasda", "asdasdasda", "asdasdsa"] like this. i try to numberOfRowsInSection return 3 but it collapses     typeOfPasajeroNameLastName(isExpanded: false, pasajeroNumber: ["Pasajero 1"], pasajeroType: ["Adulto"], nombre: ["dasdad dasda"], apellido: ["asdasd asdas"], birthDate: ["24/05/1994"]),     typeOfPasajeroNameLastName(isExpanded: false, pasajeroNumber: ["Pasajero 2"], pasajeroType: ["Adulto"], nombre: ["asdad"], apellido: ["asda asdasd"], birthDate: ["21/04/1994"]),     typeOfPasajeroNameLastName(isExpanded: false, pasajeroNumber: ["Pasajero 3"], pasajeroType: ["Bebé"], nombre: ["asdas"], apellido: ["asdasd asdass"], birthDate: ["08/08/2018"])   ]   extension PasajerosPaso2View: UITableViewDelegate, UITableViewDataSource {       func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {          if !arrayUiText[section].isExpanded{         return 0       }     return arrayUiText[section].nombre.count //this returns 1 i want returning 3         }       func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {               if indexPath.row == 0 {       let cell = tableView.dequeueReusableCell(withIdentifier: "pasajerosData", for: indexPath) as!

Hi developers, im doing a framework with this functionpublic func LoginGenerateToken(userName: String, password: String) { let parameters = LoginGenerateTokenStruct(userName: userName, password: password.sha256()) LoginSingleton.shared.mailUserLogin = userName networkManager1 = URL_Session() networkManager1?.delegate = self networkManager1?.LoginGenerateTokenPOST(parameters: parameters) }so when the user install the framework and call this function it should ask for 'userName' and 'password'but it doesn't because is not an static functionthe function get call like thisLoginWS.LoginGenerateToken()insted ofLoginWS.LoginGenerateToken(userName: String, password: String)i can't set static because im calling a delegate outside the func LoginGenerateTokennetworkManager1?.delegate = selfhow could i get the function to work without using static?this is the full code// // LoginWS.swift // IntegradorFrameWork // // Created by BlumonPay on 11/27/19. // Copyright © 2019 BlumonPay.
