Embarking on the journey of Swift Macros? Ensure a successful voyage with these four indispensable insights that every developer should know. In this session, we'll delve deep into: 1. The Intangibility of Your Code: Grasp the concept that, in the macro world, your code hasn’t materialized yet. It remains a textual entity, implying that the Swift Macros will carve out new code from the one it's linked to, setting limits to its visibility. 2. The Imperative of Test-Driven Development (TDD): When navigating the terrains of Macros, employing TDD isn't just a recommendation; it's the gold standard. Discover how TDD emerges as the most optimal strategy in macro implementation. 3. Harnessing the Might of Swift Syntax: While starting off with string literals might seem an easier route, the journey becomes more profound and clean when you harness the Swift Syntax API. Unlock the tools and tactics that will refine your macro code, making it more efficient and legible. 4. The 'Do's and 'Don'ts in Macro Creation: While the world of macros offers vast possibilities, it comes with its set of cautionary tales. Delve into the pitfalls of actions like file reading and networking within macros and understand the intricacies of debugging challenges they might bring along. Join me to elevate your Swift Macro skills, steer clear of common pitfalls, and craft efficient, clean, and robust macro code.
