We love football (yes, it’s a pre-requirement)
Featured by Google & Apple
Xamarin is cool
I ❤ C#, I’m sure you too
Xamarin apps are fairly reliable and fast*
* Millions of our users can confirm!
Complete API coverageSame-day support for new releases
After all… It’s cross-platform!
Sounds like Xamarin is perfect… But?
But it’s not
FotMob
• Started as Android-first app – 2008• iOS (C#) – 2011• WP7 & Windows 8 (C#) – 2012
Very UI-intensive application
Xamarin
Extra layer between you and user
No cocoapods, JCenter, (almost) no StackOverflow, no hope
Bugs
... and other 300 (opened / confirmed “iOS” bugs); 5000+ bugs for all categories
Xamarin-apps are “heavy”

* Visual Studio doesn’t sound like an ideal solution either

* Not only because I’ve been working there for 3.5 years
Acquisition is always a risk
Windows Phone is dead

– Can we be featured? – Sure, do you watchOS 2.0 support? – .... – And what about now? – Have you watched WWDC? Our new notifications are amazing! –
You don’t want this to happen. Trust me.
Same-day support != working product
Ok, so what’s the status now?
We have rewritten so far to Swift:• Apple Watch App• Today Extension• Notification Service Extension• Notification Content Extension• All data model & parsers & utils classes
We have released semi-Swift-version with support all new iOS 10 features and have been featured
Xamarin still does not support 3D-touch-notifications *
Core app will be rewritten and scheduled to be released in Q1 2017
* 24th of October
