Usage

Typhoon provides three retry policy strategies:

/// A retry strategy with a constant number of attempts and fixed duration between retries.
case constant(retry: Int, duration: DispatchTimeInterval)

/// A retry strategy with an exponential increase in duration between retries.
case exponential(retry: Int, multiplier: Double = 2.0, duration: DispatchTimeInterval)

/// A retry strategy with exponential increase in duration between retries and added jitter.
case exponentialWithJitter(retry: Int, jitterFactor: Double = 0.1, maxInterval: UInt64? = 60, multiplier: Double = 2.0, duration: DispatchTimeInterval)

Create a RetryPolicyService instance and pass a desired strategy like this:

import Typhoon

let retryPolicyService = RetryPolicyService(strategy: .constant(retry: 10, duration: .seconds(1)))

do {
    _ = try await retryPolicyService.retry { 
        // Some logic here ...
     }
} catch {
    // Catch an error here ...
}

Requirements

• iOS 13.0+ / macOS 10.15+ / tvOS 13.0+ / watchOS 6.0+ / visionOS 1.0+
• Xcode 14.0

Installation

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but typhoon does support its use on supported platforms.

Once you have your Swift package set up, adding typhoon as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/space-code/typhoon.git", .upToNextMajor(from: "1.0.0"))
]
