I've been an iOS Developer since 2008, working with Swift since '14 and SwiftUI since '19. Right when the Vision Pro was presented in '23 I was interested in visionOS and gave many talks at conferences about the topic. I also give talk about ethical subjects such as the environment or privacy. https://speakerdeck.com/stuffmc 2014-09-21 04:28:39 -0400 A lot of time Privacy of my data as a user is not a priority for Developers. Wether it’s my calendar, my contacts, my location, photos, I want as a user to be able to use an app without all of those attacks in my privacy. I summarise here some things an iOS developer should do to ensure the most critical user can still use an app in some regards, and not just say “I need all your information” like on other platforms. This is the beauty of iOS, being able to have fine grained control over your data (although not enough) so let’s do this all together, as a beautiful community concerned by Privacy. This talk will also be a “State of the Union” where we are in 2025, since many new additions arised since I wrote my book about Privacy. Most notably, I will try to motivate you to support iOS 18 as the lowest, for many Privacy reasons. A lot of time Privacy of my data as a user is not a priority for Developers.

That was the beginning of my career as an iOS developer, with the SDK coming just 1 year later. But the love for the iPhone didn’t wait for the SDK. Then I went through it all: the iPad, longer and bigger iPhones, the same with the iPad, Apple TV, Apple Watch etc … and every year came a new iPhone, a new iOS (and at the launch of iOS 7 I almost had to cry, where had my skeumorphism gone?!). And then there was always the other side of me: Green politics and an attempted switch to full-time politics in 2024, which unfortunately failed in 2023. The day after my political defeat there was WWDC and the presentation of Vision Pro and I was back. Motivated again because visionOS and Vision Pro are at least as revolutionary (actually more so) to me as the iPhone and iOS, or iPhoneOS. In this talk I summarise what some of you may already know, but everyone will definitely learn something. I have been intensively involved with the new platform since the keynote. Even more intensively since the SDK came out. Even more intensively since I was at Apple in Munich. The revolution has already begun. At best, not everyone may have noticed it yet. In this lecture we will take a closer look at the Vision Pro and its hardware as well as the different possibilities of the SDK, i.e. visionOS. We will look at how you can show your existing iPad and iPhone apps in Shared Space, as well as immersive Spaces and 3D objects.

Still, he realises one cannot be more important than the other over the last ten years. In this talk, he will explain why if we don’t work together, at every level, the world as we know it, the so-called civilisation will be over in 10 to 15 years. We’re the new dinosaurs. Let’s try to survive instead of writing the next feature in the next sprint. This sprint — the one for our future — is a way bigger story.
