In this article, you will find the top 5 programming languages for iOS development. You can find their best use cases along with the pros and cons of each language. But before we go into the list, let’s look at what you need to consider before building an iOS app.
What To Consider Before Building An Ios App?
1. Know Your Target Market
Before you build your iOS app, it is essential to have details of the people you target to use the app. Having details of the target audience and how they usually use their devices will give you an idea of how to design the app and which features matter most to these people.
Knowing your target audience will also make it easier for you to run ad campaigns for the app because you know exactly who you are communicating to. So, start by doing market research to determine your target users based on gender, age, location, and any other relevant criteria.
2. Know The Problem You Are Solving
While planning to build your iOS application, you need to have a clear idea of the problem you are trying to solve. This should always be the first step because if your app is not solving any problem in the market, it will not be used by anyone. This will also help you determine if you have competitors.
3. The Scope Of Your Application
After defining the purpose of the app, you now need to determine the different capabilities your application will have. For instance, if you are building a fitness application, you need to determine the exercises to include in the app. You can always expand the scope of the app in the future, but initially, it’s best to set a strong foundation in terms of what you’ll cover at the start.
4. What Devices To Support
Apple has been making iPhones since 2007, so you need to decide which of these iPhones your app will support. Your app’s functionality will help you determine the iOS devices with the necessary database to run it. Knowing the devices capable of running your app will help you determine the iOS versions to build the app for.
5. Evaluate Your Capacity To Build The App
Building an application is no easy task and will require several people with different development skills. So, before you start writing your first line of code, it is crucial to evaluate if you have the necessary talent to build the kind of app you want.
Some of the specialists you may need on the team include; Frontend and backend Developers, UX Designer, UI Designer, Graphic Designer, and even QA developers and Project Manager.
For startups, you can have one developer play two or three of the above roles. However, eventually, you may consider hiring remote developers who can help you scale your application.

The Five Best Ios Development Languages
Swift is a programming language created by Apple to build apps for all their operating systems, including iOS, iPadOS, macOS, tvOS, and watchOS. It is among the most popular programming language and is ranked 14th according to the Tiobe index – a platform that ranks programming languages according to their popularity.
Apple created Swift with the aim of making it easier and quicker for developers to build apps in the Apple ecosystem. Some of the frameworks that work with Swift include; Cocoa, Cocoa Touch, CloudKit, AVFoundation, and many more.
The best use case for Swift programming language
It is best to use Swift when you want to build iOS apps quickly and with the flexibility of scaling them up in the future. Swift has a relatively shallow learning curve, so it is pretty easy for developers to get started using this language. Apple also regularly updates Swift to make a much faster, more reliable, and secure programming language for building iOS apps.
Pros and cons of Swift
- Easy to learn and use
- Stable and reliable
- Regular updates
- Good scalability
- Enables fast development of apps
- Automatic Memory Counting
- There are not so many Swift developers out there
- Limited community support compared to other languages like Python, Java, and C++.
C# is a cross-platform, object-oriented programming language created by Microsoft in 2000. Since C# is a cross-platform language, it can be used to develop iOS applications too. As far as popularity is concerned, C# is the 5th most popular programming language as of March 2022. Many developers love C# because of its ability to create apps for multiple platforms.
The best use case for C#
It is best to use C# if you plan to build iOS and Android applications. It would also be ideal to use this language if you already have C# developers on your team.
Pros and cons of C#
- Great community support since it is a popular and mature language
- High performance
- It has a huge library
- Cross-platform support
- Easy to use
- There are many C# developers
- Scalable and updateable
- It has a relatively steep learning curve for beginners
- Limited flexibility since it is based on the Microsoft.NET framework
3. Objective C
Objective C is an extension of the C programming language with object-oriented programming capabilities. This language was developed in the early 1980s. It is the language that was used to create OS X and iOS plus their APIs. So, it can also be used to build iOS applications.
According to Tiobe, Objective C is the 20th most popular programming language used by over 4.1% of developers worldwide. Just like C#, Objective C is also cross-platform, so it can be used to create apps for multiple operating systems, including macOS and iOS.
The best use case for Objective C
Objective C is an old and probably outdated programming language (It was last updated in 2016). You should only consider using it if you are building apps for older iOS devices that are not supported by Swift. But if you want to build apps for next-generation iOS devices, using Objective C is not a good idea.
