Objective-C, Apple’s original programming language, forms the cornerstone of MacOS and iOS. Being object-oriented, it expands upon C while introducing new functionalities.

Swift is swiftly eclipsing Objective-C as the primary iOS developer’s choice. In 2022, almost 5% of developers adopted Swift, compared to around 2% for Objective-C.

However, there’s still value in acquiring Objective-C skills. Much of Apple’s historical code remains in this language, and a complete migration will take time.

Objective-C Suits When:

  • Creating new iOS apps, especially for older iOS versions
  • Updating and upkeeping older iOS apps
  • Apple’s built-in apps and iOS itself rely on Objective-C

Objective-C’s Strengths:

Objective-C’s Challenges:

  • Waning popularity
  • Complicated syntax
  • The need to manage two separate code files for headers and implementation
  • Inherits security vulnerabilities from C



C# is a versatile and object-oriented programming language crafted by Microsoft. It serves various purposes. While often used for building cross-platform apps, it finds apps in games, websites, software, web APIs, and beyond. In 2022, C# achieved the 7th position among the best programming languages for professional developers.

The ability to create iOS apps using C# is facilitated by Microsoft’s .NET Multi-platform App UI (MAUI) framework. This dynamic duo is often paired with the Microsoft Visual Studio IDE. This collaboration lets you craft the app on a Windows-based system. However, a connection to a Mac is required to publish it on the App Store.

C# + MAUI Suits When

seeking efficiency and cost-effectiveness for multi-platform app launches. When you utilize a unified C# codebase to operate the app across iOS, Android, macOS, and Windows, you can use it.

Notably, the Olo app exemplifies this approach, leveraging C# at its core while integrating platform-specific elements to enhance user experience.

C# + MAUI’s Strengths:
