How about [weak(guard) self]? It would only work with closures returning -> ()
as if you are weakly capturing something you are likely to be messaging that
not returning some, so they can be ignored.
networkRequest.fetchData() { [weak(guard) self] result in
switch result {
case .succeeded(let data):
self.processData(data)
case .failed(let err):
self.handleError(err)
}
}
