Delegates should be prefixed with the class name. So visualStyleCompletionsControllerCompletionSuggestionsOnItemCreated. It is also bad mojo to pass through a delegate. It would be better to either expose suggestionsView publicly so some other object can be its delegate, so likely the best option is to just bounce the delegate call though a similar delegate here. Delegates should also take "this" as the first argument, which ties to the reason the class name is in the method. It should not be assumes that the delegate is a 1-to-1 relationship, and they might need to know who is calling them.

Also completionSuggestionsOnItemCreated does not make much sense to me currently. Would visualStyleCompletionsControllerCustomizeCompletionElement make sense?

This would have a new method signature that includes the class name. It should also pass this to that method. So:

this._delegate.completionSuggestionsViewCustomizeCompletionElement(this, itemElement, completions[i]);

Then VisualStyleCompletionsController would implement that, and fire off visualStyleCompletionsControllerCustomizeCompletionElement.
