Hi, I'm adding steps:
First launch I set LoginAndRegisterContainerView with navigationcontroller
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let windowScene = (scene as? UIWindowScene) else { return }
let contentView = LoginAndRegisterContainerView()
//
let window = UIWindow(windowScene: windowScene)
let navigationView = UINavigationController(rootViewController: UIHostingController(rootView: contentView))
window.rootViewController = navigationView
self.window = window
window.makeKeyAndVisible()
}
Later in MyView I want to change rootViewController
DispatchQueue.main.async {
let vc = UIHostingController(rootView: Home())
let sceneDelegate = UIApplication.shared.connectedScenes.first?.delegate as! SceneDelegate
let window = sceneDelegate.window
window?.rootViewController = vc
UIView.transition(with: window!, duration: 0.4, options: .transitionFlipFromRight, animations: {}, completion:
{ completed in
// maybe do something on completion here
})
}
is it the right way?( at the end my view hierarchy looks like this:

I want to pick an image with PHPickerViewController. But this causes to memory link. Can anyone help me with this issue?(

I'm trying to show multiple cells and their own data models in the same tableView. I added segment control for this and I delete all tableview current data and removed the current data sources and binding new data and its cell. But I am getting the below error message :( If you have any offers please help me :(
P.s: Each segment's cells and sections design is different than each other.
Error: Thread 1: "attempt to insert section 0 but there are only 0 sections after the update"
In View Model:
private func bindSelectedSegmentIndex() {
/// reset pagination and limit for new request
selectedSegmentIndex
.observe(on: MainScheduler.instance)
.do(onNext: { _ in
/// remove all old api data in tableviews
self.transactionsAndDepositsTableViewData.accept([])
self.contractsTableViewData.accept([])
self.pagination = Pagination()
self.updateTableViewDataSource.accept(())
})
.subscribe(onNext: { [weak self] _ in
guard let self = self else {return}
switch self.selectedSegmentIndex.value {
case 0,1:
self.callUserTransactionsAndDeposits()
case 2:
self.getContracts()
default:
return
}
})
.disposed(by: disposeBag)
}
In ViewController:
@IBAction func segmentControlChanged(_ sender: UISegmentedControl) {
self.hapticImpactMedium()
let selectedIndex = sender.selectedSegmentIndex
self.viewModel.selectedSegmentIndex.accept(selectedIndex)
}
fileprivate func setupTransactionsAndDepositsDataSource() {

Hi. Can I set a time and run any code at a specific time? For example after 2 days. But the application will not run or be in background mode. I've read about Background Tasks. But everyone runs their code in background mode (in-app run). I want to make that special time :) Thanks in advance
Hi everyone. I want to bind the URLSessionDelegate protocol with the custom protocol that it confirmed from URLSessionDelegate. But I can't catch its functions on the protocol. Can you tell me where I went wrong?

Guideline 5.1.2 - Legal - Privacy - Data Use and Sharing
The app privacy information you provided in App Store Connect indicates you collect data in order to track the user, including Crash Data. However, you do not use App Tracking Transparency to request the user's permission before tracking their activity.
Starting with iOS 14.5, apps on the App Store need to receive the user’s permission through the AppTrackingTransparency framework before collecting data used to track them. This requirement protects the privacy of App Store users.
I am getting this rejected message from apple. But I added AppTrackingTransparency to my project and alerts when the app launches. What must I do for the next step?
P.s I am using Firebase's Crashlytics.
struct AppDelegateHelper {
static func askAppTrackingTransparency() {
// Request user authorization to access app-related data for tracking the user or the device.
if #available(iOS 14, *) {
ATTrackingManager.requestTrackingAuthorization { status in
switch status {
case .authorized:
print("Allowed to AppTrackingTransparency")
break
case .denied: break
case .notDetermined: break
case .restricted: break
}
}
} else {
// Fallback on earlier versions
print("Can't ask AppTrackingTransparency")
}
}

Hey everyone. I have created a new framework, may I create a new bundle for my assets, xib... can I keep it inside itself?
Hi. How can we set structure complex in ui. For example, if we imagine have app's main content contains some ui - different collection views, another sections and end of all we have comments which is shows another page's bottom area.
I think I'll solve it with creating different viewcontrollers - one for collection views, another for comment section... and with addchild i'll add all of that to Main controller.
Is this way is well ?
CommentController which is gets comments and adding that section to some controller what i want. is this right ?

guard let cell = tableView.cellForRow(at: indexPath) as? ConverterTableViewCell,
let code = cell.currency.text
else { return }
cell.priceText.text = "0"
convertCurrencyForCode(with: code)
cell.priceText.delegate = self
cell.priceText.addTarget(self, action: #selector(textChanged(_:)), for: .editingChanged)
cell.priceText.addTarget(self, action: #selector(onTextFieldTap), for: .touchDown)
writedNumber = 0
tableView.reloadData()
cell.priceText.becomeFirstResponder()
selected = indexPath.row
}
@IBAction func textChanged(_ textField: UITextField) {
if let text = textField.text {
writedNumber = Double(textField.text!)
tableView.reloadData()
