Now it’s time for a rewrite.

New architecture. New backend.
Same spirit. Same city.

The rebirth of Zaraz Jadę begins. 💪

Of course, we are already prepared for new winners! 🏆

Are you ready for the #SwiftStudentChallenge? 🥳

In 2022, my first daughter was born, which slowed down the project and eventually brought it to a complete freeze a year later. 🍼

Nearly three years have passed since the last update. Now, it's time to return! 🎉

#DevDiary #iOSDev

Everyone said, "Use AWS! It's cheap and reliable!" ☁️

I didn't follow that advice. Instead, my goal was to find cheap and functional solutions. 🛠️

Over time, further improvements were made, and the project grew. App received difficulties notifications from RSS. 📩

#DevDiary

Just one Mac, reading endless lines of text and transforming them into something commuters could rely on.

Initially, my schedule files were a jumble of disordered lines. Then came a breakthrough: access to a proper database.

Finally, real schedules! 📅

#DevDiary #SwiftLang

There was no fancy API, no GTFS feeds. #Warsaw provides only massive text files containing something similar to CSV. 200 MB files that were parsing by 2️⃣ hours on the #MacMIni.

Every night... ⏰

That’s how the first data pipeline for the app began.

#DevDiary #iOSDev #Backend

Sometimes, the best apps emerge from small annoyances that evolve into significant ideas. 🌱

That night transformed my perspective on transport apps forever. 🚀

Tomorrow, I'd like to share a bit more about the technical side. It truly was magical! ✨

#DevDiary #BuildInPublic

One of my greatest achievements was the complete implementation of #accessibility. 🌟

Zaraz Jadę became the first app to fully support #VoiceOver. The main catalyst was Roman, who introduced me to the world of sounds by sharing the essential knowledge. 👨‍🦯

#DevDiary #IndieDev

After returning from Christmas, I already had my first prototype. Over the next 4 years, I regularly developed the project. 🎄

The main features of the Zaraz Jadę App include real-time vehicle positions, timetables, difficulties, routes, and stop descriptions. 🚌🕒🗺️

#DevDiary

So, it's time to act, and that will be the story for the coming weeks! ✨🚀

#DevDiary #Swift #BuildInPublic

It contributed data to my project, Zaraz Jadę - an app that provides the locations of trams and buses in Warsaw. 🚌

It processed timetables, routes, and other data that reached users. 🕒

Unfortunately, the data source has dried up... 😔
#DevDiary #publictransport #BuildInPublic

I want to tell you the story of an amazing computer.

It doesn’t just crunch data, it warns the city 🚨 by sending alerts about route changes and difficulties across Warsaw.

Not bad for a 16-year-old machine running 24/7. This tiny little guy has a lot to do.

#DevDiary #Macmini

#Plans
I want to finish the #ZarazJade refactor before the end of the year. It will include several additional features. 🚂

This means I will also bring back another project of mine! #GeoJSON is key to a good transit app! 🗺️

I love what I do! I end the year with a bang! 💥

#Community
@MobileWarsaw #100 was insane! We had more than a 💯 RSVPs and many people on the waiting list! 🥳🎉

Our team always wanted to organize a bigger event, but after @simonbs commented that it was a small conference, the thought came - maybe we're doing it every month? 🤔

#Development
I have begun developing my private Swift Clean Architecture. 🚀

This fully modular approach is based on Clean Architecture but is adapted for the #SwiftUI environment. It includes support for Coordinates and ecosystem functionalities. 🛠️

#architecture #development

#Projects
This time, I'm ready with a big project that will combine #Swift with #PublicTransport. This will resurrect my old app, Zaraz Jade, which lost its data source. 🚀

This involves a new arch, ideal tools, and thorough preparation, all to be developed as #BuildInPublic. 🔧
