A monthly community blogging event. One host, one topic, everyone writes.
Each month a host picks a topic. You write a post on your own blog, then share the link. The host collects everything into a roundup.
Pick a month, choose a topic, rally the community.
Need inspiration? These prompts are open for any host to pick up and make their own.
How to encode business rules directly into types so invalid states become uncompilable, not just untested.
Write a parser and interpreter for a domain-specific language using enums, indirect cases, and pattern matching.
Pick one accepted SE proposal and trace it from pitch through review to implementation, showing how the language sausage gets made.
Unusual and creative uses like validated inputs, feature flags, or lazy-logged properties.
An honest look at runtime dynamism trade-offs, message sending, and what got lost in translation.
Real production pain points, deployment stories, and where Vapor/Hummingbird actually shine vs. where you’d still reach for something else.
Practical actor reentrancy pitfalls, TaskGroup choreography, and structured concurrency patterns that only emerge in real codebases.
Building a Swift macro from scratch and reflecting on when metaprogramming helps vs. when it just confuses your future self.
Writing CLI tools, text parsers, or Markdown processors in Swift for personal productivity pipelines.
Illustrating how structs, classes, enums, and existentials actually sit in memory, with diagrams that make ARC and copy-on-write click.
Take a pattern from Rust, Haskell, or Kotlin and show how it maps onto idiomatic Swift — and where the analogy breaks.
Build something genuinely useful in 50 lines or fewer of Swift, proving that the language can be concise when you let it breathe.
