    Did you know that most of the time you want to use `v` instead of `po` or `p` in lldb? This is something that majority of Swift developers don't realise but `v` is alias for `frame variable` that was added back in Xcode 10.2, it's faster and more reliable way to get your info

    "LLMs write terrible code" No. YOU suck at learning how to use new tools. You're feeding it nothing, getting the average of its training data, then complaining about it. Saw it with my tools: some learned and got 10x out of that time, some complained.

    📰 Published a New Article and oss lib: Hot Reloading in Swift, a technique I've used for over a decade now to save hours of development time per week. A lot of folks asked me over the years how I can produce so much, this is part of the answer 🪄

    a former CEO’s asked me why do the other devs leave after 5pm (they were working 8 hours) since there is still ‘work to be done’, I told him there is always more work to be done and that they don’t have % stake like he has so why would they work for free, he was quite shocked

    Oh for fucks sake 🙄. Don’t sacrifice your 20s – or any other decade of life! – on the erroneous belief that unless you work round the clock, you’re not going to be “successful”. The world is full of people who were all work and now are all regret.

    🚀 Launching a new project github.com/krzysztofzablo… your go-to hub for community-curated Macros, insightful articles, and valuable tools. Swift Macros opens a new frontier for our code. They can replicate many of the use-cases previously covered by Sourcery. Need inspiration

    Sourcery Pro is now available. The price will go up when I add upcoming features like Cloud template repository and more powerful editor. If there was ever a good time to show your support for the decade I spent build tools for the community it's now. apps.apple.com/us/app/sourcer…

    🌟Sourcery Pro is the most advanced Xcode Source extension ever made. Do you hate writing protocol mocks, adding Codable conformance,or just writing same patterns over and over again? Now it's just a click away, and you can write your own templates too apps.apple.com/us/app/sourcer…

    PKL format from @Apple looks interesting, a single definition can be used to generate a ton of different configuration formats like yaml, json, plist and also supports code generation for many languages! Check it out! pkl-lang.org/index.html github.com/apple/pkl
