Modernize Objective-C to Swift
 
 

Converting Objective-C to Swift modernizes iOS and macOS applications with safer, more concise syntax. Our AI converter translates Objective-C's verbose bracket syntax to Swift's clean dot notation, header/implementation files to single Swift files, and manual memory management hints to Swift's automatic reference counting. Perfect for migrating legacy iOS apps to Swift, reducing codebase complexity, improving type safety and eliminating common crashes, or learning Swift by seeing Objective-C equivalents. Swift's optional types prevent nil-pointer crashes that plague Objective-C, while type inference reduces boilerplate dramatically.

 
 
 
 
 
 
Conversion Features
 
 
 
Syntax Modernization
 

Transforms Objective-C syntax to Swift. Square brackets [obj method] become obj.method(), @interface/@implementation merge to class, @property becomes var/let, and verbose selectors convert to function calls.

 
 
 
Optional Safety
 

Converts Objective-C pointers to Swift optionals. Nullable pointers become Type?, non-null guarantees use regular types, nil checks become optional binding (if let), eliminating null-pointer crashes.

 
 
 
Header File Elimination
 

Merges Objective-C .h/.m files into single Swift files. Interface declarations and implementations combine, reducing duplication and improving maintainability. Access control uses Swift modifiers instead of separate headers.

 
 
 
Protocol Conversion
 

Converts @protocol to Swift protocols. Protocol methods become protocol requirements, optional methods use Swift's optional requirements, and delegates convert to Swift protocol patterns with type safety.

 
 
 
 
 
 
 
FAQs
 
 
 
How is Objective-C syntax converted to Swift?
 
Objective-C's verbose syntax becomes Swift's concise syntax. Square bracket method calls [obj method] become dot notation obj.method(), @interface/@implementation become class definitions, and header files merge into single Swift files.
 
 
What happens to Objective-C pointers?
 
Objective-C pointers convert to Swift references or optionals. Strong pointers become regular references, weak pointers become weak var, and nil pointers become Swift optionals (Type?). Manual retain/release is eliminated by Swift's ARC.
 
 
Can it modernize legacy iOS apps?
 
Yes! The converter helps modernize Objective-C iOS apps to Swift. Classes, view controllers, and business logic convert to Swift syntax, enabling gradual migration while maintaining compatibility through Swift-Obj-C bridging.
