iOS Staff Engineer @DisneyPlusHS, pushing the boundaries using @SwiftLang. In my free time trying to balance on border between art and technology.

Just letting you all know I started using a different social network as the primary one, expect most of my activity there: https://t.co/VYXA2H1K4p

Another contribution to open-source. ✅

The chance that some of the apps on your Apple device contain the code I have written or were made using some of the developer tools I have contributed to is getting higher. Lottie, Firebase, Fastlane and counting. #hacktoberfest

Still think not having any iOS conference on the Greek island of Ios is a missed opportunity…

[Matěj Kašpar Jirásek @mkj_is]

@rokejulianlockh @Apple Yes, it has. But since it is in 3D space it is working a bit differently than desktop.

Have been trying to learn how to work with windows in #visionOS.

[Matěj Kašpar Jirásek @mkj_is]

@BrianRoemmele No worries, happy to see it is living its own life.

@YokoAdda Looks like someone is ripping me off. 🫠

[Matěj Kašpar Jirásek @mkj_is]

As I was optimizing Lottie files to dotLottie format to improve performance and app size, I found out there was no tool for batch converting them. So I made one. https://t.co/LDkpytc0Wh

Today I learned you can enable notifications for performance regressions in the #Xcode Organizer window. 😮

It seems like it is a great time to share this again.

[Matěj Kašpar Jirásek @mkj_is]

I backed up my #Twitter on a #receipt. 206 tweets on 507 cms. Does anybody want a backup too?

@ishabazz Two newlines will create a new paragraph, space before newline will make a line break.

@ivancimr09 Díky! Ty asi nejsi naše cílovka, že by ses díval na seriály na telefonu… Leda, že bys pouštěl na iPadu pohádky vnoučatům. Honzu přesvědčit, to by chtělo nějakou hodně velkou páku…

[Matěj Kašpar Jirásek @mkj_is]

Job update: Three months ago I joined @DisneyPlusHS. After almost 10 years working at agencies I decided to try something else at a totally different scale. So, this is the way for me right now.

[Matěj Kašpar Jirásek @mkj_is]

@ankeetmaini I am happy to have an opportunity to work with you. 😊

[Matěj Kašpar Jirásek @mkj_is]

One of the key factors for me was going remote first – I like my home city and being close to the family, but wanted to have a larger impact.

[Matěj Kašpar Jirásek @mkj_is]

I got an opportunity to become a part of the Core iOS team. Responsible for performance, libraries and tools and I quite like this challenge.

[Matěj Kašpar Jirásek @mkj_is]

I added async-await support to my CombineMIDI open-source library, you can see the difference there:

[Matěj Kašpar Jirásek @mkj_is]

Finally managed to dig deep and experiment with the new #SwiftLang concurrency. What I like the most so far is how much easier it is to use AsyncStream in comparison to writing custom Combine Publisher with subscription.

[Matěj Kašpar Jirásek @mkj_is]

Few days ago I released small open-source #SwiftLang package with additions to the #SwiftUI Binding type. I hope you find them as useful as myself. https://t.co/6gO9rmNLhD
