K Hi folks! Small survey from our team about ObjC interop. I will appreciate your votes and feedback!

Q: In your experience with Kotlin/Native development, have you ever had to use the @Suppress("CONFLICTING_OVERLOADS") annotation (documentation) to suppress errors when overriding methods from Objective-C protocols and classes?

1️⃣ Yes, I’ve frequently used it in my projects.
2️⃣ Yes, I’ve occasionally used it in my projects.
3️⃣ Yes, I have used this annotation, but only in samples, not in real projects.
4️⃣ No, I have overridden Objective-C methods, but I didn’t use this annotation.
5️⃣ No, I have never overridden any Objective-C methods.

If you have used this annotation, please share in 🧵 what specific protocols or classes methods you overrided.

I have used this annotation (some time ago) with Core Bluetooth related code, e.g. CBCentralManagerDelegate.

For mobile:
WKWebView navigationDelegate:

object : NSObject(), WKNavigationDelegateProtocol {
            @Suppress("CONFLICTING_OVERLOADS")
            override fun webView(
                webView: WKWebView,
                didCommitNavigation: WKNavigation?
            ) {
                onPageStarted()
            }

            @Suppress("CONFLICTING_OVERLOADS")
            override fun webView(
                webView: WKWebView,
                didFinishNavigation: WKNavigation?
            ) {
                onPageFinished()
            }
..

Using it for functions in CBCentralManagerDelegateProtocol
AVCaptureVideoDataOutputSampleBufferDelegateProtocol

CBPeripheralDelegateProtocol
NSNetServiceBrowserDelegateProtocol
SKPaymentTransactionObserverProtocol

[mkrussel]

I used it when implementing MKMapViewDelegateProtocol.

[Alex Azarov]

UITableViewDelegate is another example where the annotation is needed

Why do you want to know which ones we have been overriding?
