Axiom UIKit-SwiftUI Bridging FAQs

Question 1

Does this skill support the latest iOS 18 features?

Accepted Answer

Yes, it includes specific guidance for iOS 18+ features such as UIGestureRecognizerRepresentable and the unified animation framework that allows SwiftUI animations to apply to UIKit views.

Question 2

When should I use UIViewRepresentable vs UIViewControllerRepresentable?

Accepted Answer

Use UIViewRepresentable for individual UIKit views like MKMapView or custom drawing views. Use UIViewControllerRepresentable for full controllers like UIImagePickerController, SFSafariViewController, or any component that manages its own view hierarchy.

Question 3

Can I use SwiftUI views inside a UIKit UITableView?

Accepted Answer

Yes, for apps targeting iOS 16 and later, you can use UIHostingConfiguration to host SwiftUI views directly within UICollectionView or UITableView cells with native performance.

Question 4

How do I sync state between UIKit and SwiftUI?

Accepted Answer

State flows from SwiftUI to UIKit via the update method, and from UIKit to SwiftUI using the Coordinator pattern. The Coordinator acts as a delegate for the UIKit view and updates @Binding properties in the parent SwiftUI struct.

Question 5

Why is the Coordinator pattern necessary?

Accepted Answer

Coordinators are reference types that provide a stable home for delegate protocols and data sources. Using closures within SwiftUI structs often leads to retain cycles or compilation errors because structs cannot act as objc-compatible delegates.
