🚨 Going out of business sale 🚨
iOS dev course sales plummeted due to AI. It costs a lot of money to host my courses online and with sales at basically $0, I've cancelled that hosting.
This closes down the site which unfortunately removes access to the courses.
I want you to have the courses you purchased forever, so I've added the ability to download my course videos so they are yours.
I've put my recent course on sale at a large discount so you can get it before it's gone and I've made old courses available for free if you want to grab those too.
The school will be online until November 24th so you have a few weeks to download these videos at seanallen.teachable.com
Thanks for learning with me and supporting my work over the years. I appreciate it.

nerdsniped, here is how ChaGPT app does it github.com/zats/chatgpt-keyb… they are not shying away from private APIs, TLDR:
- UIKeyboard.activeKeyboard provides the live keyboard view
- walk through superviews to find the rendered keyboard host, capture it as a snapshot
- UIKeyboard.setKeyboardAlpha:0 keeps keyboard active but makes it transparent
- transparent non-key window presents the snapshot above the app
- UIBlurEffect.effectWithVariableBlurRadius:imageMask: applies a progressive blur across the live app content and keyboard snapshot.

I still see people saying that agents produce bad code and don't know their way around SwiftUI
The thing is: it's definitely not a model problem anymore - all of the flagship models are beyond smart enough
You're lacking something else: youtu.be/HSvaQ5wq4zA

A month ago I promised my iPhone Duo skill would get updated for Xcode 27.1
It's done: the hinge, fold & ArrangementView sketches are now real iOS 27.1 APIs, plus new rules for vertical bars & sheets
Grab it here: github.com/FloWritesCode/fwc…
Works nicely next to Apple's own skill
iPhone Duo is coming and your agents won't have a clue how to build for it
So I turned all the new documentation, APIs and developer sessions into an agent skill
Grab it here: github.com/FloWritesCode/fwc…
The skill will get updated as new APIs / Xcode 27.1 gets introduced

Yesterday I asked what everyone does while waiting for their agents
I try avoiding doomscrolling, so instead playing games is a nice alternative. The issue is that they pull you in and you miss your agents' updates...
So I (Cursor) built a Minecraft Mod that shows all ongoing + recently finished Cursors & Codex agents. It also lets you reply to them & start new agents.
Grab it here: github.com/FloWritesCode/age…

87% of apps in our Apple Retention Messaging sample offer a discount or plan switch
Fewer than 1% of those offers get accepted
Before testing a bigger discount, try reminding people what they’re paying for

App Store Connect just dropped a new update.
You now can control how your app appears in search results, as well as set product page header images (like big apps have been able to for a while.
Another nice quality-of-life update is they made it so you can now finally preview what your app looks like in the App Store to see if your screenshots will actually line up right.
