using qualtrics in a SwiftUI app with a UIViewControllerRepresentable - ios

Question

I'm trying to make a simple swiftui app using qualtrics and I'm trying to use a uiviewrepresentable to make it work
#main
struct QualtricsPocApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
init() {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
// i have the actual intercept id's here i just removed them
Qualtrics.shared.initializeProject(brandId: "brand", projectId: "proj", extRefId: "ref", completion: { (myInitializationResult) in print(myInitializationResult);})
return true
}
}
}
struct QualtricsViewRep: UIViewControllerRepresentable {
typealias UIViewControllerType = UIViewController
func makeUIViewController(context: Context) -> UIViewController {
let vc = UIViewController()
Qualtrics.shared.evaluateProject { (targetingResults) in
for (interceptID, result) in targetingResults {
if result.passed() {
let displayed = Qualtrics.shared.display(viewController: self, autoCloseSurvey: true)
}
}
}
}
on let displayed = ... I keep getting the error "Cannot convert value of type 'QualtricsViewRep' to expected argument type 'UIViewController'", how can I return this code as a UIViewController to use in a swiftui app, or is there some other way I should be approaching this?

Answer 1

Unfortunately I don't have Qualtrics installed, but I have worked with it within UIKit. My assumption here is that you will need to create an instance of a UIViewController. This view controller is what the qualtrics view will present itself over.
Ultimately, you will return the view controller which contains the qualtrics view presented over it.
struct QualtricsViewRep: UIViewControllerRepresentable {
typealias UIViewControllerType = UIViewController
func makeUIViewController(context: Context) -> UIViewController {
let vc = UIViewController()
Qualtrics.shared.evaluateProject { (targetingResults) in
for (interceptID, result) in targetingResults {
if result.passed() {
DispatchQueue.main.async {
let vc = UIViewController()
let displayed = Qualtrics.shared.display(viewController: vc, autoCloseSurvey: true)
}
}
}
}
return vc
}
func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
// your code here
}
}

Sample Qualtrics SwiftUI App
I had to implement this for work so I decided to share my solution.
QualtricsDemoApp
import SwiftUI
import Qualtrics
#main
struct QualtricsDemoApp: App {
var body: some Scene {
WindowGroup {
ContentView()
.task {
Qualtrics.shared.initializeProject(brandId: "BRAND_ID", projectId: "PROJECT_ID", extRefId: "EXT_REF_ID") { myInitializationResult in
print(myInitializationResult)
}
}
}
}
}
ContentView
import SwiftUI
import Qualtrics
struct ContentView: View {
#State private var showFeedback = false
var body: some View {
VStack {
Button("Show Qualtrics Feedback") {
showFeedback.toggle()
}
if showFeedback {
QualtricsFeedbackRepresentable()
}
}
.font(.title)
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
struct QualtricsFeedbackRepresentable: UIViewControllerRepresentable {
func makeUIViewController(context: Context) -> UIViewController {
let vc = UIViewController()
Qualtrics.shared.evaluateProject { (targetingResults) in
for (_, result) in targetingResults {
if result.passed() {
Qualtrics.shared.display(viewController: vc)
}
}
}
return vc
}
func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
}
}
Now I just have to figure out why it's not in English. 😃
