Hi All.
It seems that if you have an escaping closure argument, you can’t make it
optional. Am I right?
init (
owner:AnyObject,
handler:@escaping (HXObserverNotification)->Void
) {
self.owner = owner
self.handler = handler
}
You could try this:
init (
owner:AnyObject,
handler:@escaping ((HXObserverNotification)->Void)?
) {
self.owner = owner
self.handler = handler
}
You get “@escaping attribute only applies to function types”
Or you could try this:
init (
owner:AnyObject,
handler:(@escaping (HXObserverNotification)->Void)?
) {
self.owner = owner
self.handler = handler
}
You get “@escaping attribute may only be used in function parameter position”
