Key differences between Swift and Objective_C

CharacteristicSwiftObjective_C
SyntaxSwift has a more modern and concise syntax compared to Objective-C.Objective-C has a more verbose and C-like syntax compared to Swift.
ParadigmSwift is a multi-paradigm language that supports both object-oriented and functional programming.Objective-C is primarily an object-oriented language.
TypingSwift has strong static typing with type inference.Objective-C has weak dynamic typing.
PerformanceSwift is generally faster than Objective-C due to its optimized performance characteristics.Objective-C is slower than Swift due to its dynamic nature.
Libraries and frameworksSwift has a growing ecosystem of libraries and frameworks, but it may have fewer options compared to Objective-C.Objective-C has a mature ecosystem of libraries and frameworks with extensive options.
Community and supportSwift has a large and active community with good support from Apple.Objective-C has a long-standing community and good support from Apple.
Learning curveSwift has a relatively low learning curve, especially for developers familiar with modern programming languages.Objective-C has a steeper learning curve, especially for developers new to C-based languages.
