SwiftNIO

Apple

SwiftNIO is Apple's asynchronous, event-driven networking framework for building high-performance servers and network clients in Swift. It supplies low-level networking primitives rather...

Pros

More powerful and scalable networking foundation than Swifter
Widely used by Vapor and other Swift server projects
Strong control over event loops, channels, and protocols

Cons

Much lower-level and harder to learn than Swifter
Requires implementing or selecting routing and HTTP abstractions
More boilerplate for a basic web server

Network

Apple

Network is Apple’s native framework for connections over TCP, UDP, Bonjour, and related transports. It is intended for developers building networking features...

Pros

First-party integration across Apple platforms
Built-in network path monitoring and connection management
More modern Apple API than low-level BSD socket wrappers

Cons

Limited to Apple platforms compared with SocketKit
Less appropriate for Linux server-side Swift
API availability varies by operating-system version

Starscream

Dalton Hubble

Starscream is a Swift WebSocket client library for Apple platforms. It handles WebSocket handshakes, framing, compression, and connection events for apps that...

Pros

Higher-level WebSocket API than SocketKit
Includes WebSocket framing and protocol handling
Well suited to real-time mobile and desktop clients

Cons

Focused on WebSocket clients rather than general TCP and UDP sockets
Primarily targets Apple platforms
Provides less server-side networking functionality than SwiftNIO

BlueSocket

Kitura

BlueSocket is a Swift library for creating and managing TCP and UDP socket connections. It targets server-side and cross-platform Swift developers who...

Pros

Supports both TCP and UDP socket operations
Thinner abstraction than full networking frameworks
Works across major platforms supported by Swift

Cons

Smaller and less active ecosystem than SwiftNIO
