Top 10 iOS app development tools
iOS app development tools are a set of software tools used by developers to create, design, test, and deploy iOS applications.
These tools include programming languages such as Swift and Objective-C, integrated development environments (IDEs) such as Xcode, frameworks such as UIKit and SwiftUI, and performance analysis tools such as Instruments.
They allow developers to create a wide range of applications, from simple utilities to complex games and enterprise-level solutions.
Using iOS app development tools, developers have the ability to create robust and efficient applications that run on Apple’s operating system and take advantage of the latest technologies and features available on iOS devices.
This blog is meant for anyone willing to learn about iOS app development. Now let’s explore the most useful tools we use here at DECODE.
Table of Contents
Xcode
We can’t talk about iOS app development tools without talking about Xcode.

source: Xcode
Xcode is a comprehensive integrated development environment (IDE) developed by Apple Inc. for building applications for macOS, iOS, watchOS, and tvOS.
Important features
Here are some of the key features of Xcode:
- Interface Builder
Xcode provides a drag-and-drop interface builder that allows developers to create user interfaces quickly and easily. It also includes tools for designing custom views and layouts. - Debugging tools
Xcode includes a powerful debugger that helps developers find and fix bugs in their code. The debugger supports breakpoints, stepping, and profiling tools to help developers optimize their code. - Source control integration
Xcode integrates with Git and other source control systems, making it easy for teams to collaborate on code and manage version control. - Instruments
Xcode includes a suite of performance analysis tools called Instruments, which helps developers identify and fix performance issues in their code. - iOS simulator
Xcode includes an iOS simulator, which allows developers to test their apps on a variety of devices and operating systems without needing physical hardware. - App Store Connect
Xcode includes an integrated workflow for submitting apps to the App Store. Developers can manage their app metadata, submit builds for review, and track their app’s performance directly from Xcode.
Pros and cons
Pros
- Swift support
- powerful debugging
- Easy navigation
Cons
- Steep learning curve
- Limited to Apple
Pricing
Xcode is available as a free download on the Mac App Store. There are no upfront costs or licensing fees to use Xcode.
However, in order to publish apps to the App Store or distribute them through other Apple channels, developers must enroll in the Apple Developer Program, which has an annual fee of $99 USD.
The Developer Program provides additional resources and support for app development, as well as access to beta software and tools.
It’s important to note that while Xcode itself is free, developing for Apple’s platforms may require purchasing additional hardware such as Mac computers or iOS devices.
CocoaPods
Among iOS app development tools, CocoaPods is up there with the most important ones.

source: CocoaPods
CocoaPods is a dependency manager for iOS and macOS projects that makes it easy to add third-party libraries and frameworks to your Xcode project.
It simplifies the process of managing dependencies by automating the installation and configuration of external code, making it easier for developers to focus on building their apps.
