OCaml vs Swift: What are the differences?
Key Differences between OCaml and Swift
OCaml and Swift are two different programming languages with different features and purposes. Here are the key differences between the two:
Type Inference: OCaml is a statically typed language with strong type inference capabilities. It can automatically infer the type of variables based on their usage. On the other hand, Swift also supports type inference, but it is a statically and strongly typed language that requires explicit type annotations in some cases.
Functional Programming Paradigm: OCaml is primarily a functional programming language that supports features like pattern matching, higher-order functions, and immutable data structures. In contrast, Swift is a multi-paradigm language that supports both functional and imperative programming styles. It allows mutating state, imperative control flow, and object-oriented programming.
Memory Management: OCaml uses automatic memory management through a technique called garbage collection. It frees the programmer from worrying about memory allocation and deallocation. In contrast, Swift uses Automatic Reference Counting (ARC), where memory deallocation is handled by keeping track of references to objects. It does not have a garbage collector.
Concurrency Model: OCaml provides lightweight threads (also known as cooperative multitasking) and supports locking and synchronization mechanisms for concurrent programming. Swift, on the other hand, supports both lightweight threads and a more fine-grained approach to concurrency using async/await, actors, and structured concurrency.
Tooling and Ecosystem: OCaml has a well-established compiler and tooling infrastructure, with powerful libraries and frameworks for various domains. It is widely used in academia and industry, particularly in the functional programming community. Swift, on the other hand, has been developed by Apple and has excellent tooling support, focused mainly on iOS, macOS, watchOS, and tvOS app development.
Platform Compatibility: OCaml is a cross-platform programming language that can be compiled to various architectures and operating systems, including Linux, macOS, and Windows. Swift, initially designed for Apple's platforms, is primarily used for developing applications targeting iOS, macOS, watchOS, and tvOS, although there are efforts to bring it to other platforms as well.
In summary, OCaml is a statically and strongly typed functional programming language with automatic memory management and excellent tooling support, while Swift is a multi-paradigm language with type inference, automatic reference counting, support for concurrency, and a focus on Apple's platforms.

Cons of OCaml
- Small community3
- Royal pain in the neck to compile large programs1
Cons of Swift
- Must own a mac5
- Memory leaks are not uncommon2
- Very irritatingly picky about things that’s1
- Complicated process for exporting modules1
- Its classes compile to roughly 300 lines of assembly1
- Is a lot more effort than lua to make simple functions1
- Overly complex options makes it easy to create bad code0
