Xamarin

Vorteile

Xamarin comes in a few flavours. There is Xamarin.Forms which is a totally unified development experience across all apps. You're more limited & restricted in what you can do, but at the payoff of being able to develop once across all platforms.
Xamarin.IOS and Xamarin.Android are C# wrappers for the native libraries, so you're basically writing a native app but in C# and are able to share code between platforms using a portable class library or a .net standard library.
Also it's totally free and backed by Microsoft. They keep up to date with the latest libraries really well and has large community support.

Nachteile

There is a bit of a learning curve with all Xamarin - and certain levels of understanding really help you out. But it can be confusing when you're looking at examples and unsure of how it applies to your own code.

Xamarin.Forms has a lot of restrictions, but if your goal is to make a simple native feeling form-y application and don't want to do anything specific, it can save a lot of development time.

With Xamarin.IOS and Xamarin.Android you're in a bit of trouble if no one has created bindings for a library you want to use, you can do it yourself but it's not well documented and can be confusing.

If you don't like Visual Studio and C# this is not for you.

Vorteile

The best thing is it is owned by Microsoft so you will get regular updates, tutorial, and blogs for understanding new features, security measures introduced. You need not to hire separate developers for IOS & Android & it will eventually reduce development time. You can also develop native apps along with cross-platform. Development is basically C# based so learning is easy for developers working on Microsoft Technologies

Nachteile

Only IDE available for development is Microsoft Visual Studio costing of which may be a concern for smaller organizations.

Vorteile

Xamarin is the best available cross platform for mobile application development. The platform works with #C and .Net frameworks to design stylish and smother applications. Support forums are easily available of this. 90 percent code is shareable in pcl class library.

Nachteile

Xamarin provides limited access for the open source library functions which can be improve. When comes to iOS development it has support limitations.

Vorteile

We currently use Xamarin for both mobile application development, and we are looking at using it for development of OSX apps too.
Development is easy once you have a bit of knowledge, getting your head around the way to code in Xamarin is relatively easy, and after that you can develop in .NET (we use C#) without many issues. Adding features which require native code is easy enough too, and wrappers are easy to find to do this for you.

Nachteile

Xamarin forms are still not as good as we would like, so we tend to produce native user interfaces for each platform. We have hope that forms will reach a good enough standard to be used in most cases soon though.

Vorteile

For programmers who already use C#, Xamarin is a very natural choice. The transition is smooth since all the syntax is the same, and is just like learning a new .NET module. This is my favourite part of the framework, because developers need very little training if they already know C#.

Nachteile

Sometimes it can be quite buggy and doesn't give you the level of detail for errors you might want. For example, if the app crashes on the phone, quite often the program will just stop and not give any output instead of some kind of error message.

Vorteile

We can reuse source code to a great extent speeding up the engineering cycle. Its look and feel and behavior is very close to native app. Also due to its cross-platform application, Xamarin makes maintenance and updates easier.

Nachteile

With Xamarin, you have to use only the components provided by the platform and some .Net open source resources. Xamarin's main benefit is the ability to share your code across the platforms. Yet, you can only share the logic, UI code will be mostly platform-specific. This makes building games, rich custom UI, or complex animations in Xamarin pretty pointless.

Vorteile

Since Xamarin allows packages / add-ons from the nuget.org website, or can install any package from nuget.org, which saves writing code for these functions. It is a very comfortable way when developing projects.

Nachteile

The Visual Studio emulator is a little slow and has a somewhat confusing intrefaz, besides that it consumes many resources in a computer.

Vorteile

Xamerin primarily chosen because of our familiarity with C#. It is a lesser learning curve if you already have the c# resources. We have found it very easy from start to finish to deployment of mobile applications

Nachteile

One problem we keep running into is remote build server for iOS builds. The connection to the remote build server gets disconnect or can not connect we have to remove temp files to get the connection back

Vorteile

Possibilità di sviluppare in un solo linguaggio e di implementarlo in più piattaforme. Numerose estensioni disponibili e aggiornamenti continui. Disponibilità di una versione gratuita completamente funzionale.

Nachteile

Sarebbe utile un tool di progettazione grafico per creare le interfacce utente. Il debugger su device iOS è molto lento e inutilizzabile.

Vorteile

possibilità di utilizzare un solo linguaggio per sviluppare in multipiattaforma, presenza di una edizione free, aggiornamenti e miglioramenti continui, possibilità di utilizzare il git

Nachteile

sarebbe utile migliorare il debug sui vari simulatori, spesso è lento o si blocca. Necessaria una macchina Apple per poter collegare il debugger per iOS.

Vorteile

- The best thing about Xamarin is that with the same programming language, I can develop applications on all the platforms of the market, as it says: "Write once, execute on all platforms".
- In case of an error, the correction will be applied on all platforms.
- The applications developed are completely native

Nachteile

This platform uses C # language for application development, so those who do not have experience with this language will have to learn it, the good news is that it is a friendly language, easy to learn and manage

Vorteile

Xamarin an efficient cross application development platform works with #C and dot net frameworks. Xamarin form design is pretty much attractive as we can code it to make brilliant UI. There is a certified Developer course of Xamarin from official University. Overall you can build an outstanding application in low cost.

Nachteile

This platform also has some limitations as for iOS it support limited functionality as compare to Android. You must need proficiency in #C and dot net to get into Xamarin.

Vorteile

As soon as you are having some experience with C# and Microsoft development ecosystem, Xamarin would be your default selection for a development of any iPhone, Android and Windows application. Platform has evolved significant through the years and nowadays it is difficult to think of another way to develop native cross-platform applications without it.

Nachteile

Heavily reliant on Microsoft ecosystem. Might be troublesome for new comers. There are many other 'free' alternatives to it.

Vorteile

Thanks to xamarin's multiplatform build option we dont need use more than one language to developer.

Nachteile

I believe native development can be faster but compare it its fast development advantage that is not a big problem.

Vorteile

simple maintenance, open source tech, easy to use, up to date programming languages support

Nachteile

limited access to open source libraries, difficult to use with apps with lots of graphics

Vorteile

It offers an easy developing environment that can be useful if you know what you're doing with the software.

Nachteile

It takes many hours of research before you will feel comfortable navigating the software and doing something useful.
