| Objective-C | Swift |
| Syntax | C style syntax with small-style message passing | Modern and Concise Syntax |
| Safety | More permissive and allows runtime errors | Strong focus on safety - enforcing memory safety, nullability check, type safety |
| Performance | Not faster than Swift | Swift uses advanced compiler optimisation techniques. |
| Interoperability | Compatible with both C and C++ | Swift needs bridging headers to work with Objective-C code base. |
| Learning Curve | Harder to learn compared to Swift | More beginner friendly and easier to learn. |
