Leaking View Model in sink

A sink closure keeps the view model alive forever via a retain cycle.

class SearchViewModel {
    var cancellables = Set<AnyCancellable>()
    @Published var query = ""

    func bind() {
        $query
            .sink { value in
                self.handle(value)
            }
            .store(in: &cancellables)
    }

    func handle(_ q: String) { /* ... */ }
}
