Whether you are targeting an Android or iOS operating system will impact your strategy for developing the application. Objective-C 2.0 provided an optional conservative, generational garbage collector. When run in backwards-compatible mode, the runtime turned reference counting operations such as “retain” and “release” into no-ops. All objects were subject to garbage collection when garbage collection was enabled. Regular C pointers could be qualified with “__strong” to also trigger the underlying write-barrier compiler intercepts and thus participate in garbage collection.
Though Objective C is fast, it takes a lot of time to code in Objective C. Due to its complex structure, it is tedious to write the program in Objective C. Objective C supports all the Object-Oriented concepts, making it even more compatible with C++. Usage of Object-Oriented concepts makes Objective C more secure and powerful as a programing language. Our team can make recommendations for you with regard to your development approach and help you build the next, great product on iOS. In instances where a specific custom solution is necessary for the product (e.g. specific color change or integration), Objective-C is easier to connect with private APIs. As Swift is constantly developing, it is unstable and this fact may result in some crashes from these sorts of connections.

Swift may only be used in applications that run on iOS 7 and later. Nevertheless, because of its design, Swift cannot be utilized in legacy applications that employ earlier operating system versions. Yet, fewer than 5% of Apple devices now use iOS 8 or an older version, according to the findings of a recent survey. Cross-platform support that is lacking Swift is compatible with Linux, Windows, and all Apple systems, as we already said.
- Objective-C is a high-level general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language.
- Among apps, existing in Featured-sections in AppStore and Google Play there are no any cross-platform apps except game projects.
- It is designed to be safe and performant with modern syntax and features.
- Cross-platform support that is lacking Swift is compatible with Linux, Windows, and all Apple systems, as we already said.
- Swift provides safeguards to prevent errors and improve readability.

Recommendation for When To Use Objective-C
Objective-C uses reference counting for memory management, which can be less efficient than other approaches. However, Objective-C may also limit developers to iOS development, which is less universal and accessible than Android development. The table below outlines additional pros and cons of Objective-C.
Though it remains slower than Swift, its core speed is faster. To sum it up, Objective-C, when compared to Swift, is a more outdated language and lacks modern tools and properties. Swift has many updates and ongoing growth plans, and the language receives great support from Apple. It is an easy-to-learn, secure, modern, and interactive programming language. Swift has simplified coding patterns as well as coding interface vs Objective-C. Another main issue with Swift lies in its ABI instability.
Speed of Coding
In the following four statements, increasingly specific type information is provided. The statements are equivalent at runtime, but the extra information allows the compiler to warn the programmer if the passed argument does not match the type specified. A formal protocol is similar to an interface in Java, C#, and Ada 2005. It is a list of methods that any class can declare itself to implement. Objective-C 2.0 added support for marking certain methods in a protocol optional, and the compiler will not enforce implementation of optional methods. An informal protocol is a list of methods that a class can opt to implement.
Since then, the number of apps on the Apple App Store has increased. Airbnb, Facebook , LinkedIn , Lyft, Slack , Uber are just a few examples of businesses that use Swift extensively in their software development process. Swift is easy to Read and Write because it is a clean and expressive language that has simplified Syntax and Grammar. It requires a lot less code performing the same takes when compared to Objective-C.

Other types from C, like values and structs, are unchanged because they are not part of the object system. This decision differs from the C++ object model, where structs and classes are united. Instances of NSLock claim that they will provide an implementation for the two instance methods. Objective-C was extended at NeXT to introduce the concept of multiple objective c vs swift inheritance of specification, but not implementation, through the introduction of protocols. This is a pattern achievable either as an abstract multiple inherited base class in C++, or as an “interface” (as in Java and C#). Objective-C makes use of ad hoc protocols called informal protocols and compiler-enforced protocols called formal protocols.
As it has routes from a C language, products integrating parts of C or C++ code operate smoothly. On the contrary, Swift is incompatible with the C++ language. Indeed, Swift’s maturity and production readiness are confirmed by the fact it powers apps like LinkedIn, Lyft, Khan Academy, Airbnb, Eventbrite, Sky Guide, Wikipedia, Coursera, https://www.globalcloudteam.com/ Slack, and VSCO. In most cases, Swift is a better choice over Objective-C for building iOS apps. Since Objective-C has been somewhat superseded by Swift, many of its libraries and tools aren’t maintained anymore. We explore the differences below, including performance and features, plus when to choose one over the other.

Objective-C and C++ are not the same programming languages. Although they share similarities, as both are object-oriented and based on C language, they have different features and capabilities. It also means that the issues will be reported for a long time as the use cases arise. There are a few options when it is more preferable to use Objective-C instead of a new iOS programming language- Swift. First, if an app has already been written in Objective-C and has a huge codebase (100,000+ code lines).
Again, because Swift is young, it doesn’t support versions earlier than iOS 7.0 and macOS 10.9. Therefore, it’s impossible to create universal apps that will be able to support all platforms. The main goal of Swift developers was to build a simple language that everyone can easily pick up. This leads to other benefits such as reduced development time and the ease of learning for newbies. This feature helps interpret the developer’s thinking and simplify the code.
