Xamarin

Avantages

We just need to create different UI for different OS. Create a shared project for all back end communication. Can save lot of times from business perspective and create a impactful application.

Inconvénients

iOS UI should be created within Xamarin only. No need to open xcode for that.

Avantages

Xamarin is an incredibly powerful cross-platform development tool that allows for easy code sharing and a streamlined workflow.

Inconvénients

Although Xamarin is relatively easy to use, it is not as intuitive as some of the other development tools on the market and lacks some of the more advanced features that could be useful for experienced developers.

Avantages

The most that I like about Xamarin it is cross-platform

Inconvénients

it is too complicated to create an application with this one

Avantages

- First and foremost, it's portability that is driving the market. Being able to write a single implementation which targets multiple platforms is extremely cost effective
- Being backed up by .Net (extremely common among the software development community) it's far easier to maintain a Xamarin solution (as opposed to having to find native platform developers)
- Hardware support is really at an all time high - even hardware producers (e.g.: Motorola) are putting out Xamarin SDKs.

Inconvénients

- Perhaps the only true disadvantage is that there is always a delay before it gets updated to support the latest platform update
- Debugging can become tedious and I've seen this especially on the native implementations due to Xamarin's less-than-optimal way of reporting an issue (i.e.: you may end up in situations where an error message related to an Android run-time was actually caused by some small layout issue where a needed element is not present)

Avantages

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.

Inconvénients

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.

Avantages

The best thing with this framework is that it offers single code base that is used to develop software for multiple OS, like I can use the same code for developing app that can run on Android, iOS, Windows and macOS

Inconvénients

App build up times are still slow, it takes a while to deploy the application when compared to other frameworks

Avantages

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

Inconvénients

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

Avantages

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.

Inconvénients

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

Avantages

I like the most on this software is the capability to create mobile application on android and IOS with a single code base. Xamarin has rich control libraries which is compatible for IOS and Android devices which save a lot of development time.

Inconvénients

Xamarin is not beginner friendly. A user must have a fundamental knowledge on application developement with android and ios.

Avantages

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.

Inconvénients

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.

Avantages

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#.

Inconvénients

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.

Avantages

It is an extremely useful platform for cross-platform mobile app developers. Since it is backed by Microsoft, it has all features, frameworks, tools and services supports by Microsoft. It is thus far the most successful and robust cross-platform framework to develop native android and iOS mobile apps.

Inconvénients

The device emulators are not very useful when it comes to developing complex apps. It has a big and bit of complex learning curve. For those who are not familiar with .NET C#, the learning curve extends

Avantages

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.

Inconvénients

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.

Avantages

The big virtue of Xamarin is simplicity and interporability, if you are a C# programmer with regular skills on MVC and Mobile Development you can create functional apps in a short time.
The capability to publish your apps on Android, Mac OS and if needed Windows Mobile, allows you to enable enterprise level apps for must osf your expected users. Also common shared code for your projects reduce the amount of work you need. Current templates covers must of common use cases and all you need is customize your user experience.

Inconvénients

The big contra is that user interfaces are not so easey to customize as several advanced features are sacrified in order to achieve multiplatform capabilities. Also as expected apps are not so fast as the native ones created with Android Studio or Xcode.

Avantages

Building Xamarin apps allows me to deploy mobile apps to both android and iOS. It saves me a ton of development time.

Inconvénients

The UI code is still platform specific, and often tough to work with as you are not working with the native language of the platform. Though the time saved from deploying the same business logic to multiple platforms makes Xamarin a home run.

Avantages

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.

Inconvénients

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

Avantages

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

Inconvénients

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

Avantages

The text editor to go to if you are new and looking to make Android or IOS apps. Xamarin makes it possible to develop smartphone apps without learning all that technical know-how. All you need is basic knowledge of C#

Inconvénients

Unfortunately, going the easy way isn’t necessarily the best way. So, Xamarin let you take shortcuts to make an app, but it can lead to struggles with the build. Also, if you’re using Xamarin free version then you will be very limited compared to the full version.

Avantages

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.

Inconvénients

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

Avantages

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

Inconvénients

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.

Avantages

- 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

Inconvénients

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

Avantages

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.

Inconvénients

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.

Avantages

Xamarin is now integrated with Visual Studio and together they make programming, especially for mobile, extremely easy. Writing code once and being able to share it across Windows, Android, iOS and MacOS is something I didn't think would be possible when I started coding. Xamarin is a life saver.

Inconvénients

I love this software. I don't have anything bad to say about it.

Avantages

Easy to use, cross platform, includes prebuilt templates for different development projects

Inconvénients

None really, other than it can take up quite a bit of space on your hard drive ~20gb

Avantages

Being able to code mobile application by just using C# and then you can publish to Android, iOS and even Windows Phone is just simply incredible.

Inconvénients

This technology is still young and may still have some bugs. Also the Visual Studio emulator is verrry slow, so I just use a physical hardware on my development.
