Help with objc_util delegates

I'm trying to get some objc_util code working that involves a delegate, however I just can't seem to find the right syntax for expressing the delegate method.
Can anyone help? Code is below and the delegate I'm targeting is defined here:
I'm marshalling access to the objc_util code through a singleton which is initiated within the app using InApp. initialize()
BTW the code is running in the AppTemplate in Xcode.
from objc_util import * def PurchaseController_fetchAvailableProducts(_self, _cmd): obj = ObjCInstance(_self) sk_class = ObjCClass("SKProductsRequest") products_request = sk_class.alloc().init(productIdentifiers=[InApp.PRODUCT_ID]) products_request.delegate = obj products_request.start() def PurchaseController_canMakePurchases(_self, _cmd): sk_class = ObjCClass("SKProductsRequest") return sk_class.canMakePayments() def PurchaseController_purchase(_self, _cmd): pass def PurchaseController_purchaseMyProduct(_self, _cmd): pass def productsRequest_request_didReceiveResponse(_self, _cmd, request, response): #defined here: https://developer.apple.com/documentation/storekit/skproductsrequestdelegate/1506070-productsrequest InApp.receive_products(response) class InApp: PRODUCT_ID = "Purchase001" Instance = None @classmethod def initialize(cls): cls.Instance = InApp() @classmethod def receive_products(cls, response): cls.Instance.products_received = True self.products = ['Dummy1', 'Dummy2'] def __init__(self): self.products =  self.products_received = False ObjCClass('NSBundle').bundleWithPath_('/System/Library/Frameworks/StoreKit.framework').load() superclass = ObjCClass("NSObject") methods = [PurchaseController_fetchAvailableProducts, PurchaseController_canMakePurchases, productsRequest_request_didReceiveResponse] protocols = ['SKProductsRequestDelegate', 'SKPaymentTransactionObserver'] purchase_controller_class = create_objc_class('PurchaseController', superclass, methods=methods, protocols=protocols) purchase_controller = purchase_controller_class.alloc().init()

The method name is
which turns into
you seem to have an extra request in the name...

Many thanks that's done it. I was a bit thrown by the syntax of how an objective-c delegate maps to the python method, but I think I get it now. I know precious little objective-c which isn't helping!
