What Is iOS?

iOS is a mobile operating system created and developed by Apple Inc. It exists as part of a larger ecosystem of operating systems such as macOS, watchOS, and tvOS. iOS is exclusive to the iPhone and iPad hardware.

What Is an iOS developer?

An iOS developer is a developer that is able to build native iOS applications using Apple’s proprietary IDE XCode as well as leveraging the power of programming languages like Swift and/or Objective-C.

Swift is the primary programming language that is supported by Apple for developing iOS applications. It’s predecessor Objective-C is currently on it’s way out, however, it’s still used to maintain legacy systems both within Apple’s codebases as well as other companies who have yet to re-write their applications using Swift. 

In today’s world, iOS developers are expected to know Swift as well as have a comprehensive understanding of Apple’s iOS frameworks. In a sense, they can be considered full-stack developers because they will be responsible for designing both the frontend and backend of a mobile application. 

Only rarely, such as the case for large teams and agencies, will you see frontend and backend roles be separated.

There is little to be known outside of Apple’s technology ecosystem when it comes to iOS development, save for when dealing with databases. 

Apple does not support cloud databases and therefore a developer will have knowledge in one or more, such as Google’s Firebase.

Popular Mobile App Databases

There are many databases to choose from when building a mobile app. Here are some popular databases to build iPhone apps. You can select the best database for your mobile app based on your requirements.

MySQL: An open-source, multi-threaded, and easy to use SQL database. Perhaps one of the older database options around.

PostgreSQL: A powerful, open-source object-based, relational-database that is highly customizable. This is a popular option to use for web applications as well and can integrate well for iOS. 

Redis: An open-source, low maintenance, key/value store that is used for data caching in mobile applications. It’s a more simplistic option that eliminates the need to access data with SQL.

MongoDB: A schemaless, JSON document database which is known for its flexibility and scalability. This is another popular option among many web applications.

Memcached: A general-purpose distributed memory caching system that has multi-threaded capabilities. It’s used primarily for caching objects to speed up applications by alleviating database load.

MariaDB: A popular open-source relational database that was created by the original developers of MySQL. Apparently it’s capable of completing INSERT statements up to 24% faster than MySQL thanks to its index/cache system.

Cassandra: A free and open-source, NoSQL database which is designed to handle a large amount of unstructured data across many different servers. It boasts high availability with no single point of failure. 

SQLite: Embedded database, common usage is to provide local data storage capabilities on mobile phones. For many web and mobile applications, this is a default option that works best for smaller-scale projects without too much complexity. 

InfluxDB: An open-source, time-series database. Influx is written in Go which makes it extremely fast thanks to Go’s low-level nature.

RethinkDB: An open-source, document-oriented database that stores data in JSON format. RethinkDB is capable of syncing in real-time with applications.

Riak DB: A distributed NoSQL database that offers high availability, fault tolerance, and data resiliency. It’s also open-source with enterprise and cloud versions. 

CouchDB: A document-oriented NoSQL database, CouchDB uses JSON to store data. JavaScript is also its main query language.

Couchbase: A NoSQL document-oriented database that is able to serve concurrent users. 

ArangoDB: An open-source, NoSQL database that supports three database models. It only uses one database at its core along with AQL query language. 

Why Build Your App on iOS?  

Powering a large portion of the western world’s mobile experience, Apple’s iOS is the second-largest mobile operating system in the world in terms of users. 

iOS has proven to be home to a very lucrative market of consumers. In fact, it’s shown that iOS users spend twice as much on in-app purchases as Android users.

It makes sense to build your app to take advantage of this profitable mobile ecosystem, but it’s also an excellent candidate due to how versatile it is with a wide range of devices it supports. iOS is available on iPhone and iPad devices, allowing apps to be accessed on both phones and tablets.

The iOS platform offers Apple’s App Store to connect mobile users with your app through search functions, categories and promotional content from Apple such as “Editors Choice” awards. 

If you create a quality app that has real demand and takes the effort to distribute it and market it in the App Store, it’s fair to say you are on your way to getting customers using your app. 

Apple goes out of its way to make In-App purchases seamless in its App Store ecosystem, allowing users to purchase in-app content at the push of a button. 

All of this combines together to create a mobile ecosystem that facilitates distributing and monetizing your mobile app, making iOS a great choice for a development platform. 

Advantages of Using iOS


Building a native app will unlock more performance than using cross-platform solutions such as React Native and Xamarin. This is due to the fact that when you are a developer natively, you are using Apple’s SDK which is the official SDK for accessing the various APIs that Apple has. 


Developing on Apple’s platforms has implicit security benefits thanks to Apple’s in-built shield against viruses and other external threats. 

iOS Alternatives & Comparisons


Not exactly an alternative, but more so another channel, Android accounts for the rest of the world’s smartphone population. To make an iPhone app with no Android app is essentially turning your back on a percentage of the market. If your strategy can afford to neglect the Android market, then iOS is likely the better option in the western world. 

React Native 

React Native is a cross-platform framework that uses the React library in order to create mobile applications that work both on Android and iOS. 

For many startups, this can be a wise choice to create a unified JavaScript-based application. However, this only makes sense if the application is not very complex or novel. 

React Native does come with some limitations as iOS and Android have many frameworks, some of which are very specialized and access hardware. 

React Native is still dependent on native languages such as Java and Objective C and therefore your code might not be 100% JavaScript, but a combination of both JavaScript and native languages. 

Another issue is that native language is much faster than JavaScript, so if your app isn’t doing any CPU intensive processes, then React Native can be a good option. If you are looking to manage your CPU footprint, then React Native just isn’t cut out for the job.

Finally, there is no guarantee that React Native will be around in the future as there is no long-term commitment to the framework.

React Native still enjoys constant updates and while this might seem like a good thing, it creates more work for a developer to do as they will have to constantly go back and update their codebase to function properly. Native development, on the other hand, is more mature.

Hire an iOS Developer

Finding a good iOS developer is slightly more difficult than finding a web developer. iOS is in a very different lane than web development in the sense that when dealing with mobile applications, you are forced to become more conscious about resources (CPU). 

Furthermore, Apple has many frameworks that the developer must become proficient at in order to make decent applications on top of learning how to deal with layouts both visually and programmatically. 

Even so, there are still many iOS developers around. However, finding a good developer is not as easy as it seems. 

With all of the freelance marketplaces and job boards around, you’d think it would be easy to find your rockstar and get started. How do you go about deciding if a developer joins your team? 

We have a great resource for you to check out that addresses that topic in much greater detail
