The OnboardingConsentView can be used to allow your users to read and agree to a document, e.g., a consent document for a research study or a terms and conditions document for an app. The document can be signed using a family and given name and a hand-drawn signature. The signed consent form can then be exported and shared as a PDF file.
The following example demonstrates how the OnboardingConsentView shown above is constructed by reading a consent form from a markdown file, creating a ConsentDocument and passing it to the OnboardingConsentView, and an action that should be performed once the consent has been given (which receives the exported consent form as a PDF), as well as a configuration defining the properties of the exported consent form.
The following example demonstrates using the OnboardingConsentView to present a consent form to the user as part of an onboarding flow.
Once the consent if completed (i.e., the user signed it and filled out all required form elements), the user can continue to the next onboarding step.
The view also uses the ConsentShareButton to allow the user to obtain a PDF-exported copy of their signed consent document.
import SpeziConsent
import SpeziViews
import SwiftUI
struct ConsentStep: View {
let url: URL
@State private var consentDocument: ConsentDocument?
@State private var viewState: ViewState = .idle
var body: some View {
OnboardingConsentView(consentDocument: consentDocument, viewState: $viewState) {
// advance your Onboarding flow in response to the user having confirmed a completed consent document
}
.viewStateAlert(state: $viewState)
.toolbar {
ToolbarItem(placement: .primaryAction) {
// give your user the ability to obtain a PDF version of the consent document they just signed
ConsentShareButton(
consentDocument: consentDocument,
viewState: $viewState
)
}
}
.task {
// load the consent document when the view is first displayed.
// this will automatically cause the `OnboardingConsentView` above to update its contents.
do {
consentDocument = try ConsentDocument(contentsOf: url)
} catch {
viewState = .error(AnyLocalizedError(error: error))
}
}
}

The Spezi Template Application provides a great starting point and example using the SpeziConsent module.
