Objective-C is an older language primarily used for iOS development, known for its dynamic typing and runtime flexibility, while Kotlin is a modern language focused on Android development, offering a more concise syntax and enhanced safety features. Objective-C is often seen as more complex due to its verbosity and learning curve, whereas Kotlin's ease of use and interoperability with Java make it a preferred choice for Android developers.
