To become a mobile app developer, there are 5 essential skills. Let's go over them
one by one. There are basically two ways to build mobile apps.
Native or cross platform. With native development, we can build an app that
runs only on a particular platform like iOS or Android. This approach
gives us full control over the capabilities of the target platform
resulting in great performance and the best user experience. However,
the downside is that if you want to build the same app for a different platform, you have to
a separate project in an entirely different language and ecosystem.
This means two separate projects and two sets of bugs to fix. That's
where cross platform or multi platform development comes to the rescue.
With cross platform development, we can reduce development time by reusing
the same code for different platforms and potentially reduce bugs.
Fixing a bug once means it's fixed across multiple platforms.
Now for native development, we have a few options. For iOS we can use
Objective C.
is an older language or swift which is modern and preferred. For
Android we can use Java which is a traditional language or Kotlin which
is modern and preferred. For cross platform development, the option depends on
the framework or tool kit we use. There are several cross platform tool
kits like react native, flutter, kotlin, multi platform, maui and a few
others. Let's dive into each one. First up we have react native which was
released by Facebook in 2015. This tool kit lets you build mobile
using JavaScript and React which is a popular library for
building web user interfaces. Some big names using React Native include
Microsoft Office, Skype and even Facebook itself. Then we have
Flutter which is a Google product that came out in 2017. Flutter
uses a programming language called Dart which takes the best parts of JavaScript,
Java and C sharp. Some examples of apps built with Flutter
are eBay, Alibaba and Google Pay. It's really powerful and
gaining a lot of traction. Now let's talk about Kotlin multiplatform.
This is the newest player released by JetBrains, the same company behind tools
like IntelliJ, PyCharm, and WebStorm. In my opinion, the best
IDEs in the world. It uses the Kotlin programming language, which is a
modern language inspired by Java. Apps like McDonalds, Netflix,
and Cash App are built with Kotlin Multiplatform. Finally, we have
Maui, which stands for .net Multiplatform App UI.
Introduced by Microsoft, Maui allows you to build native mobile and
desktop apps using C sharp and .net. These days, most companies
prefer to use multi platform development to reduce their costs.
This means we can rule out native development for now and focus on cross
platform options. Now, which framework is the best? Well, there is no such a thing as
the best framework. Yes, there are people out there like our superstar
highly opinionated developer, Mr. John Smith, who swears by react native.
But there are others with a different opinion. The reality is that neither of these
is perfect. Each has its own problems and quirks that you'll
once you start building real applications beyond YouTube tutorials.
And the reason for that is that they try to support two entirely different
platforms at the same time. So, which cross platform solution should you
choose? Well, it depends on two things. First, on what languages and technologies
you're familiar with. For example, if you're a C sharp developer, Maui
