A Combine publisher where you can specify a time interval between retries.

Publisher+RetryInterval

import Combine

extension Publisher {
    func retryWithDelay<T, E>(retries: Int, interval: DispatchQueue.SchedulerTimeType.Stride) -> Publishers.Catch<Self, AnyPublisher<T, E>> where T == Self.Output, E == Self.Failure {
        self.catch { error -> AnyPublisher<T, E> in
            Publishers.Delay(
                upstream: self,
                interval: interval,
                tolerance: 1,
                scheduler: DispatchQueue.global()
            )
            .retry(retries)
            .eraseToAnyPublisher()
        }
    }
}
