Each of these tools and technologies is useful in different ways when constructing an app that can handle millions of users. Some are used for functionality, others for API documentation, and others for hosting and user authentication.
Here are 7 of the most useful technologies used in iOS mobile app development.
1. Objective-C

Objective-C is also very well established. It dates back to the early 80s, which makes it one of the most robust programming languages for coding. It’s tried and tested, and supported by the vast majority of Apple devices.
As the name implies, it deals with objectives. If an app is a collection of discrete objectives, then Objective-C is the perfect handler.
Some of the advantages of C include:
- Support for encapsulation, data hiding, abstraction, polymorphism, and inheritance
- Support for exception handling as well as operator overloading
- Legacy support for object oriented programming.
Objective-C has a very similar structure to C, so it’s also very easy to learn for programmers.
2. SWIFT

Swift was built to make coding much easier for iOS development. Some of the features in Swift used to make iOS app development more efficient include:
● Advanced Control Flow
● Memory safe and type safe feature
● Effective error handling
● Functional programming
● Inferred type object support
Swift also includes improved safety protocols and generics compared to Objective-C.
Apple has begun to rely more on Swift for app development as it is. Apple itself says that Swift is 2.6 times faster than Objective-C. Hence, many newer iOS app developers rely on Swift. According to a Digital Skills Survey done by BrainStation, Swift is poised to overtake Objective-C in popularity.
3. Xcode

Xcode includes a suite of tools which can be used to code, test, and debug apps. It can also work on interface design. Xcode assists developers in cross device development with these tools:
- Instrument Analysis Tools
- SDKs
- Custom Instruments for Code Analysis
- SwiftUI and Interface builder
- Swift, C/C++, Objective-C Compilers
The Xcode IDE also includes support for a wide range of languages other than Swift and C variants. These include Java, AppleScript, Python, Ruby, and ResEdit.
Xcode also has support for a variety of models including API Cocoa, C-based API Carbon, and Java.
So, as you can see, Xcode is invaluable because of its inclusive nature for so many different types of developers.
It’s one of the most useful iOS mobile app development technologies.
4. Flawless

Flawless is also embedded with Xcode, which makes it a familiar tool for iOS developers. Flawless also has a lot of accessibility options including Zeplin files and Quick Hotkeys. It also supports long screen designs.
Since it’s configured with Xcode, there is also no extra setup required like third party linking.
5. RxSwift

Asynchronous programming improves app performance and responsiveness. The reason for this is the code structure and architecture employed by RxSwift. It allows for code to react and process data in a very clean, sequential way. It allows code to run in parallel, and so increases code functionality.
6. AlamoFire

Based completely on Swift, the library handles web requests and responses in both iOS and MacOS. It also includes JSON parameters and response serialization, authentication services, and network enhancement. AlamoFire has been enhanced through the years with various other libraries for newer and more powerful functionality additions.
7. Parse

Parse allows developers to store their data in the cloud and manage dashboards and push notifications. It also allows developers to run their custom code in the cloud.
Other backend functionalities include:
- Cloud-based object and file storage
- Social media integration
- Identity log-ins
- Parse analytics and hosting
- Custom code creation in the backend.
These tools are filled with incredible functionality for developers to create, customize, and deploy their apps. iOS app development is made ever more inclusive and easier by these tools. Languages like Swift and Objective-C are linked to so many other classic languages, and Xcode is integrated with app development tools.
Parse is a very capable backend tool, and AlamoFire and RxSwift provide so many functionality libraries without needing third-party integration. These technologies are some of the best for iOS mobile app development.
