Im trying to open New Contact screen in my SwiftUI app but Im not getting Save\Done button.I haven't seen anybody doing this I really don't know answer why as it seems easy at first. This is my current code.
struct ContactsVC: UIViewControllerRepresentable{
typealias UIViewControllerType = CNContactViewController
func makeUIViewController(context: Context) -> CNContactViewController {
let store = CNContactStore()
let con = CNContact()
let vc = CNContactViewController(forNewContact: con)
vc.contactStore = store
vc.delegate = context.coordinator
return vc
}
func updateUIViewController(_ uiViewController: CNContactViewController, context: Context) {
}
class Coordinator: NSObject,CNContactViewControllerDelegate,UINavigationControllerDelegate{
var parent: ContactsVC
init(_ parent: ContactsVC) {
self.parent = parent
}
func contactViewController(_ viewController: CNContactViewController, didCompleteWith contact: CNContact?) {
}
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
}
I have requested authorisation when sending contact now I want to add it.

I'm using Pulley a maps drawer library which is written in UIKit in a SwiftUI project. I have a SwiftUI ListView that I'm using in the project via a UIHostingController but I want to disable scrolling when the drawers position is not open and to do that I'm pretty sure I need to use one of the delegate functions Pulley provides (drawerPositionDidChange) but I'm not sure how to use the delegate in the Coordinator or if I should even try to use the delegate, maybe I just need to use some type of state variable?
Delegate in the view controller
#objc public protocol PulleyDelegate: AnyObject {
/** This is called after size changes, so if you care about the bottomSafeArea property for custom UI layout, you can use this value.
* NOTE: It's not called *during* the transition between sizes (such as in an animation coordinator), but rather after the resize is complete.
*/
#objc optional func drawerPositionDidChange(drawer: PulleyViewController, bottomSafeArea: CGFloat)
}
This is the UIViewRepresentable where I'm trying to use the delegate.
import SwiftUI
struct DrawerPosition: UIViewControllerRepresentable {
#Binding var bottomSafeArea: CGFloat?
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
func makeUIViewController(context: Context) -> some UIViewController {
let vc = PulleyViewController()
vc.delegate = context.coordinator
return vc
}
func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {
// Updates the state of the specified view controller with new information from SwiftUI.
}
class Coordinator: NSObject, PulleyDrawerViewControllerDelegate {
var parent: DrawerPosition
init (_ parent: DrawerPosition) {
self.parent = parent
}
func drawerPositionDidChange(drawer: PulleyViewController, bottomSafeArea: CGFloat){
self.parent.bottomSafeArea = bottomSafeArea
}
}
}
the ListView where I want to disable the scroll.
import SwiftUI
struct ListView: View {
#State private var bottomSafeArea: CGFloat?
var body: some View {
ScrollViewReader { proxy in
VStack {
Button("Jump to #50") {
proxy.scrollTo(50)
}
List(0..<100, id: \.self) { i in
Text("Example")
.id(i)
}.scrollDisabled(bottomSafeArea == 0 ? true : false)
}
}
}
}
class ListViewVHC: UIHostingController<ListView> {
required init?(coder: NSCoder) {
super.init (coder: coder, rootView: ListView())
}
}
struct ListView_Previews: PreviewProvider {
static var previews: some View {
ListView()
}
}
Here is the correct way to set up a Coordinator:
func makeCoordinator() -> Coordinator {
Coordinator()
}
func makeUIViewController(context: Context) -> PullyViewController {
context.coordinator.pullyViewController
}
func updateUIViewController(_ uiViewController: PullyViewController, context: Context) {
// Updates the state of the specified view controller with new information from SwiftUI.
context.coordinator.bottomSafeAreaChanged = { bottomSafeArea in
self.bottomSafeArea = bottomSafeArea
}
}
class Coordinator: NSObject, PulleyDrawerViewControllerDelegate {
lazy var pullyViewController: PulleyViewController = {
let vc = PulleyViewController()
vc.delegate = self
return vc
}()
var bottomSafeAreaChanged: ((CGFloat) -> Void)?
func drawerPositionDidChange(drawer: PulleyViewController, bottomSafeArea: CGFloat){
bottomSafeAreaChanged?(bottomSafeArea)
}
I am using a UIViewControllerRepresentable Class in my SwiftUI like this:
struct CalendarDayView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
return Coordinator(self)
}
func makeUIViewController(context: Context) -> DayViewController {
let dayView = DayViewController()
dayView.delegate = context.coordinator
return dayView
}
func updateUIViewController(_ dayView: DayViewController, context: Context) {
dayView.delegate = context.coordinator
}
typealias UIViewControllerType = DayViewController
class Coordinator: NSObject, DayViewDelegate {
var parent: CalendarDayView
init(_ parent: CalendarDayView) {
self.parent = parent
}
func dayViewDidSelectEventView(_ eventView: EventView) {
guard let ckEvent = eventView.descriptor as? EKWrapper else { return }
let ekEvent = ckEvent.ekEvent
endEventEditing() // Cannot find 'endEventEditing' in scope
}
}
}
In the dayViewDidSelectEventView() function i need access to the endEventEditing() function, coming from the DayViewController Class. I already try to pass the parent to the Coordinator, but that doesn't helpful. I can't access the endEventEditing() func over the parent variable like this:
parent.endEventEditing() // Value of type 'CalendarDayView' has no member 'endEventEditing'
So is there a way to access the DayViewController Class, generated by the makeUIViewController func inside Coordinator?
Can i use/pass the dayView variable
let dayView = DayViewController()
to my Coordinator so i can use functions coming from this Controller?
You can inject it in coordinator's property (having it weak to avoid cross-references).
Here is a demo:
struct CalendarDayView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
return Coordinator(self)
}
func makeUIViewController(context: Context) -> DayViewController {
let dayView = DayViewController()
dayView.delegate = context.coordinator
context.coordinator.viewController = dayView // << inject !!
return dayView
}
func updateUIViewController(_ dayView: DayViewController, context: Context) {
dayView.delegate = context.coordinator
}
typealias UIViewControllerType = DayViewController
class Coordinator: NSObject, DayViewDelegate {
weak var viewController: DayViewController? // << declare here !!
var parent: CalendarDayView
init(_ parent: CalendarDayView) {
self.parent = parent
}
func dayViewDidSelectEventView(_ eventView: EventView) {
guard let ckEvent = eventView.descriptor as? EKWrapper else { return }
let ekEvent = ckEvent.ekEvent
viewController?.endEventEditing() // << call !!
}
}
}
I am trying to implement Add Payment Method with Stripe in SwiftUI. The code works fine but it does not display the field for user Billing address. This is my code
struct AddCardView: UIViewControllerRepresentable {
#Environment(\.presentationMode) var presentation
// #ObservedObject var model: PaymentMethodViewModel
func makeUIViewController(context: Context) -> UINavigationController {
let controller = STPAddCardViewController()
controller.delegate = context.coordinator
controller.edgesForExtendedLayout = .all
let navigationController = UINavigationController(rootViewController: controller)
navigationController.navigationBar.prefersLargeTitles = true
return navigationController
}
func updateUIViewController(_ uiViewController: UINavigationController, context: Context) {
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, STPAddCardViewControllerDelegate, UINavigationControllerDelegate {
var parent: AddCardView
func addCardViewControllerDidCancel(_ addCardViewController: STPAddCardViewController) {
parent.presentation.wrappedValue.dismiss()
}
func addCardViewController(_ addCardViewController: STPAddCardViewController, didCreatePaymentMethod paymentMethod: STPPaymentMethod, completion: #escaping STPErrorBlock) {
print(paymentMethod)
// parent.model.isCards = true
parent.presentation.wrappedValue.dismiss()
}
init(_ parent: AddCardView) {
self.parent = parent
}
}
}
the code above produces this
I thought the Billing information text field will be included in the STPAddCardViewController method like this image
How can fix the code above to include text field for users to enter the card billing address?
you could try using "STPPaymentConfiguration" parameters, and call
let controller = STPAddCardViewController(configuration: ... , theme: ...)
Provide a configuration and a theme in your initialize method.
Here is sample in Objective-C.
STPPaymentConfiguration *configuration = [[STPPaymentConfiguration alloc] init];
configuration.requiredBillingAddressFields = STPBillingAddressFieldsFull;
STPAddCardViewController *addCardVC = [[STPAddCardViewController alloc] initWithConfiguration:configuration theme:[STPTheme defaultTheme]];
addCardVC.alwaysEnableDoneButton = YES;
addCardVC.delegate = self;
vc = addCardVC;

I am using SwiftUI to program a research kit app for personal use and I was wondering how to interact with Modal View opened Research Kit survey task.
I am using this code at the moment to open the view:
struct SurveyView: UIViewControllerRepresentable {
typealias UIViewControllerType = ORKTaskViewController
func makeUIViewController(context: Context) -> ORKTaskViewController {
let taskViewController = ORKTaskViewController(task: SurveyTask, taskRun: nil)
taskViewController.view.tintColor = UIColor(red:0.64, green:0.15, blue:0.11, alpha:1.00)
return taskViewController
}
func updateUIViewController(_ taskViewController: ORKTaskViewController, context: Context) {
}
}
I am using a button to call it, however I can't make it close with the cancel or done button in research kit as I am in the dark as to where I should implement the didFinishWithReason reason: ORKTaskViewControllerFinishReason.
Any help would be very much appreciated.
I have managed to do it using Coordinators. If anyone is interested, here is the code.
struct SurveyView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
Coordinator()
}
typealias UIViewControllerType = ORKTaskViewController
func makeUIViewController(context: Context) -> ORKTaskViewController {
let taskViewController = ORKTaskViewController(task: SurveyTask, taskRun: nil)
taskViewController.view.tintColor = UIColor(red:0.64, green:0.15, blue:0.11, alpha:1.00)
taskViewController.delegate = context.coordinator
return taskViewController
}
func updateUIViewController(_ taskViewController: ORKTaskViewController, context: Context) {
}
class Coordinator: NSObject, ORKTaskViewControllerDelegate {
func taskViewController(_ taskViewController: ORKTaskViewController, didFinishWith reason: ORKTaskViewControllerFinishReason, error: Error?) {
taskViewController.dismiss(animated: true, completion: nil)
}
}
}
.sheet(isPresented: $showSheet) {
STPPaymentOptionsViewController()
}
I run this code hoping to present the Stripe Payment Options View Controller in my content view and I get this error:
Instance method sheet(isPresented:onDismiss:content:) requires that STPAddCardViewController conform to View
I also tried to wrap the view into a UIViewRepresentable like so:
struct PaymentOptionsView: UIViewRepresentable {
func makeUIView(context: Context) -> STPPaymentOptionsViewController {
let config = STPPaymentConfiguration()
config.additionalPaymentOptions = .default
config.requiredBillingAddressFields = .none
config.appleMerchantIdentifier = "dummy-merchant-id"
return STPPaymentOptionsViewController(configuration: config, e: STPTheme(), customerContext: STPCustomerContext(), delegate: self as! STPPaymentOptionsViewControllerDelegate)
}
}
Then I get the error:
Type CheckOut.PaymentOptionsView does not conform to protocol UIViewRepresentable.
Considering that STPPaymentOptionsViewController inherits from ViewController you need to use UIViewControllerRepresentable instead.
You also need to implement the required delegate methods for the STPPaymentOptionsViewControllerDelegate.
struct PaymentOptionsView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, STPPaymentOptionsViewControllerDelegate {
var control: PaymentOptionsView
init(_ control: PaymentOptionsView) {
self.control = control
}
// Implement required delegate methods here:
func paymentOptionsViewControllerDidCancel(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewControllerDidFinish(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewController(_ paymentOptionsViewController: STPPaymentOptionsViewController, didFailToLoadWithError error: Error) {
}
}
func makeUIViewController(context: UIViewControllerRepresentableContext<PaymentOptionsView>) -> STPPaymentOptionsViewController {
let config = STPPaymentConfiguration()
config.additionalPaymentOptions = .default
config.requiredBillingAddressFields = .none
config.appleMerchantIdentifier = "dummy-merchant-id"
return STPPaymentOptionsViewController(configuration: config, theme: STPTheme(), apiAdapter: STPCustomerContext(), delegate: context.coordinator)
}
func updateUIViewController(_ uiViewController: STPPaymentOptionsViewController, context: UIViewControllerRepresentableContext<PaymentOptionsView>) { }
}
Keep in mind you're also setting the delegate in the STPPaymentOptionsViewController incorrectly. You need to use context.coordinator rather than self as! STPPaymentOptionsViewControllerDelegate.
