The past year has been challenging in so many ways.

COVID-19 forced us all to thrive working remotely, for both our customers and our own employees. During this past year, most of modern society inevitably adapted to the situation.

Work/life balance

At Gett, we also adapted and introduced Gett Flexi so our employees get the ultimate freedom of choice — between a 4-day week vs. 5-day week, as well as working from office or the comfort of their home.

No matter how well you adjust to working remotely though, trying to figure out how to plan a Company Hackathon, an event which…

Update: This cheatsheet is available as a Markdown table, as well as searchable CSV tables in the following repo: Thanks Joe Blau for the help and inspiration!

Update 2: I’ve released a library called RxCombine which provides a proof-of-concept for Bi-directional type bridging between RxSwift and Apple’s combine, letting you mix and match the two in your code as needed. I hope you’ll enjoy it! 😇

What a crazy WWDC week we’ve had! So many new things to learn and dig into :)

One of these new things was Combine, Apple’s asynchronous event-handling framework, now built into the…

RxSwift 5 was finally released just a few days ago, and I thought this would be a great opportunity to share a quick list of the most note-worthy changes pushed into this release.

No worries though, as this release is mostly source-compatible with only a few deprecations and renames. But it also packs a bunch of underlying improvements I’ll detail below.

Relays are now a separate framework — RxRelay

Relays are a great abstraction layer on top of Subjects that lets you relay elements without worrying about errors or completion events. Since they were added to RxSwift, they lived as part of the RxCocoa project.

Some developers were…

RxSwift & MVVM: Your First Steps

by Shai Mishali
(Hebrew, with English subtitles)

Come and learn how to get started with RxSwift and MVVM. What is really an architecture, and what MVVM aims to solve…

Welcome to Gett’s new Engineering blog! This is where individuals from our R&D will share stories, code samples, tips, thoughts, and experiments from their day-to-day work. We hope you’ll join us periodically and enjoy a quick break in your daily routine to learn some new techniques and enrich yourselves.

When you work with RxSwift, and Rx in general, every now and then you’ll discover some new piece of information that wasn’t entirely obvious to you until you’ve “hit a wall” and had to dig deeper. One of these common pitfalls is the concept of Resource Sharing. …

Not a long post this time, Just a tiny snippet of code I found useful in some scenarios :)

I noticed I’ve been seeing a lot of code similar to the following:

guard let myObject = MyObject(dependency: xyz) else { 
print("This thing is nil")

So i’ve decided to write a tiny extension to make this a bit nicer.
With the code provided at the end of this post, this would look something like this:

MyObject(dependency: xyz)
.then { doSomethingWithObject($0) }
.otherwise { print("This thing is nil") }

This is much more concicse in many cases (especially, for…

Here’s a quick recap of most of the “What’s new in Cocoa Touch” session of WWDC 2017 (Session 201). This is all typed live so if something isn’t accurate feel free to correct me :-)


Drag and Drop

Enabling Drag is done by creating a UIDragInteraction (subclass of UIInteraction) and attach it to the view you want to have Draggable (and assign its delegate).

The delegate provides data for dragged item, allows customizing the “lift” animation and customize the draggin preview.

Enabling Drop is done by creating a UIDropInteraction and setting its delegate in a similar way. …

Here is a quick recap of everything we’ve learrned from Apple during the “State of the Union” talk in WWDC 2017. Have fun!

The Big Bang Theory S06E05 — The Holographic Excitation


On September 2016, my then-fiancé-today-wife Elia and myself were supposed to celebrate our 2 year anniversary together. Unfortunately, due to my relatively new role at the digital innovation labs of Tim Hortons & Burger King (RBI Digital), I had prior commitments and a planned business trip to Manhattan right on the date of our anniversary.

My guilt of not being around for this special occasion made me wonder— how can I celebrate my 2 year anniversary with my love, while not being there with her physically? …
