SwifterSockets

A collection of socket utilities in pure Swift

SwifterSockets is part of the Swiftfire webserver project.

The Swiftfire website

The reference manual

SwifterSockets is also used in our PortSpy application in the App Store. Buyers of PortSpy get the complete sources of the project (Xcode project) used to build the App.

If you need secure connections, check out SecureSockets which is build on top of SwifterSockets (and OpenSSL).

If you are new to socket programming, check out our blog series which starts here

Features

  • Shields the Swift application from the complexity of the Unix socket calls.
  • Directly interfaces with the POSIX calls using:
    • connectToTipServer
    • tipTransfer
    • tipReceiverLoop
    • tipAccept
    • setupTipServer
  • Implements a framework on top of the POSIX calls with:
    • Connection (class)
    • connectToTipServer (returns a connection)
    • TipServer (class, produces connections)
  • Includes replacements for the FD_SET, FD_CLR, FD_ZERO and FD_ISSET macro's.
  • Builds as a library using the Swift Package Manager (SPM)

Installation

SwifterSockets can be used by the Swift Package Manager. Just add it to your package manifest as a dependency.

Alternatively you can clone the project and generate a Xcode framework in the following way:

  1. First clone the repository and create a Xcode project:

     $ git clone https://github.com/Balancingrock/SwifterSockets
     $ cd SwifterSockets
     $ swift package generate-xcodeproj
    
  2. Double click that project to open it. Once open set the Defines Module to 'yes' in the Build Settings before creating the framework. (Otherwise the import of the framework in another project won't work)

  3. In the project that will use SwifterSockets, add the SwifterSockets.framework by opening the General settings of the target and add the SwifterSockets.framework to the Embedded Binaries.

  4. In the Swift source code where you want to use it, import SwifterSockets at the top of the file.
