Swift code for RabbitMQ tutorials

Swift code examples for the RabbitMQ tutorials.

These tutorials use BunnySwift, a modern Swift 6 RabbitMQ client with async/await support.

Requirements

• Swift 6.0 or later
• macOS 14+ (or iOS 17+, tvOS 17+, watchOS 10+, visionOS 1+)
• A running RabbitMQ server on localhost

Building

Build all tutorials:

swift build

Running the Tutorials

Tutorial 1: Hello World

In one terminal, start the receiver:

swift run Receive

In another terminal, send a message:

swift run Send

Tutorial 2: Work Queues

Start one or more workers:

swift run Worker

Send tasks with varying workloads (dots indicate seconds of work):

swift run NewTask "A simple task."
swift run NewTask "A longer task..."
swift run NewTask "A very long task....."

Tutorial 3: Publish/Subscribe

Start one or more log receivers:

swift run ReceiveLogs

Emit log messages:

swift run EmitLog "Hello subscribers!"

Tutorial 4: Routing

Subscribe to specific severity levels:

swift run ReceiveLogsDirect error warning

Emit logs with severity:

swift run EmitLogDirect info "Just an info message"
swift run EmitLogDirect warning "This is a warning"
swift run EmitLogDirect error "This is an error!"

Tutorial 5: Topics

Subscribe using topic patterns (* matches one word, # matches zero or more):

swift run ReceiveLogsTopic "kern.*"
swift run ReceiveLogsTopic "*.critical"
swift run ReceiveLogsTopic "#"

Emit logs with topic routing keys:

swift run EmitLogTopic "kern.info" "Kernel info"
swift run EmitLogTopic "kern.critical" "Kernel critical error"
swift run EmitLogTopic "auth.critical" "Authentication failure"
