We’ve created an agents skill that gives all of your agents the power to understand the most complex PDFs - with dense tables, unlabeled charts, messy handwriting and more.

Our LlamaParse agents skill can be installed in one-line thanks to @vercel’s skills utility. LlamaParse orchestrates VLMs to deliver best-in-class accuracy over 40+ document types. The skills file allows agents to invoke it when needed to translate complex PDFs into agent-readable plaintext markdown.

`npx skills add run-llama/llamaparse-agent-skills --skill llamaparse`

If you prefer something fast, free, and local, you can similarly install liteparse as a skill.

Since Nov 13, 2025, Apple updated the App Store Review Guidelines (5.1).

Developers now must clearly disclose where user data is sent, including any third-party AI services.

The key part → explicit user consent. If a user declines, AI features must stay disabled.

Many apps are getting rejected because this consent screen is missing. Worth auditing your onboarding and updating flows before your next submission.

Sharing a few examples of how I implemented this in my apps (+ one from a friend).

I learned this the hard way: SwiftData or Core Data need proper versioning and @azamsharp explains why.

81 years ago today, Allied forces launched history's largest amphibious invasion, and U.S. airpower helped pave the way for D-Day.

On this #DDay81, take a moment to remember those who saved the world.

@code Hey fellow developers! I've been using VSCode for several years and want to say it was a rollercoaster ride and great experience, it helped me code mostly in JS, React, node, and other languages. Look forward to see what's next up in this year! #VS50M and #sweepstakes

I appeal to communicators around the world to tell stories of hope. Let your storytelling be #HopeTelling. Seek out the hidden crumbs of good, even when all seems lost, and allow people to hope against all hope.

That's right, I can't say it enough- get started today and boost your employable skills in 2025!! Let's go🚀

[Zero To Mastery @zerotomasteryio]

🙅‍♂️ Sick of your job? Sick of your boss? Want to live a better life?

Then do something about it!

No idea what to do? Well lucky for you, you're reading this post.

Do what 1,000s of others have done and use my 100% free guide that will take you from complete beginner to hired as a web developer in 5 months.

This step-by-step guide I'm sharing (link in next tweet) is the exact steps & resources I'd personally use if I were starting over in 2025.

By the end of the 5 months, you'll:

1. Learn to code & use AI for FREE
2. Be able to get hired as a dev

Before someone comments... NO, AI is not going to replace programmers. But you do need to learn to work WITH AI.

Forget what the haters say, learning how to code is still an extremely valuable skill, and combined with A.I. (which I'll teach you in this guide), it makes you highly valuable to companies.

No more excuses. No more worrying about other people telling you it's not possible.

Come join me (@AndreiNeagoie). Make 2025 the year you learned to code (with AI!) and got hired... 👇
