XML to Objective-C Converter

XML (eXtensible Markup Language) is used for SOAP APIs, RSS/Atom feeds, Android layouts, enterprise data exchange. Writing Objective-C models from XML by hand is repetitive and error-prone. This converter automates that step entirely — paste your XML, get Objective-C models instantly.

Generate Objective-C interface declarations with NSString/NSNumber properties for iOS legacy codebases.

How to use this converter

  1. Paste your XML into the left editor panel
  2. Click Generate
  3. Copy the generated Objective-C code from the right panel

No account. No upload. No tracking. Runs entirely in your browser.

Example Objective-C output

@interface Address : NSObject
 
@property (nonatomic, copy) NSString *city;
@property (nonatomic, copy) NSString *zip;
 
@end
 
@interface User : NSObject
 
@property (nonatomic, assign) NSInteger userId;
@property (nonatomic, copy) NSString *name;
@property (nonatomic, copy, nullable) NSString *email;
@property (nonatomic, strong) Address *address;
 
@end

The problem with manual XML-to-Objective-C mapping

Objective-C is a object-oriented, Smalltalk-influenced language — typed data models are central to how it works. Yet copying fields from XML payloads into Objective-C @interface / @property definitions introduces subtle errors:

  • Mistyped field names cause silent deserialization failures
  • Missing optional fields trigger runtime panics or null errors
  • Schema drift between API and model goes undetected until production

Objective-C uses NSCoding or NSJSONSerialization for serialization — this converter generates @interface headers with appropriate property types.

This converter eliminates the manual step entirely.

Objective-C and XML: what you need to know

Objective-C is a object-oriented, Smalltalk-influenced language, legacy iOS/macOS development and maintained Cocoa codebases. It uses NSObject subclass with property declarations for structured data — making it a natural fit for XML-driven applications.

What the converter generates

Output produces .h interface files with @property declarations using correct memory management semantics (copy, strong, nullable). Nested objects use forward declarations.

A common gotcha

Objective-C has no generics — collections like NSArray and NSDictionary are untyped unless annotated with lightweight generics (NSArray<NSString *>).

XML input characteristics

XML allows mixed content (text + child elements), namespaces, and CDATA sections — more expressive but more verbose than JSON. XML is the foundation of many enterprise integration standards including XSLT, XSD, and SOAP.

When should I use this converter?

Use this when maintaining legacy iOS codebases or developing mixed Swift/Objective-C projects that need typed model interfaces from JSON API responses.

Common use cases

  • Generating model classes for legacy iOS apps using AFNetworking
  • Creating typed interfaces for Objective-C layers in Swift/ObjC mixed projects
  • Producing model declarations for Objective-C SDK development
  • Creating typed DTOs for macOS Cocoa
  • Rapid prototyping with real XML payloads
  • Keeping Objective-C structs in sync when XML schemas evolve
  • Onboarding new team members by auto-generating the data layer
  • Validating XML contract compatibility with Objective-C type definitions
  • Generating Objective-C models from legacy iOS apps API responses

Frequently asked questions

What version of Objective-C does the output target?

The converter targets modern Objective-C conventions — Objective-C @interface headers with @property declarations. If you need output for an older version, the generated code can typically be adapted with minor changes.

Is my XML data sent to a server?

No. All conversion runs locally in your browser using client-side JavaScript. Your XML data never leaves your machine.

What XML inputs does this converter accept?

Paste any valid XML — including SOAP APIs, RSS/Atom feeds, Android layouts, enterprise data exchange. The converter infers types and generates a matching Objective-C model.

What serialization library does the generated Objective-C code assume?

The generated code is compatible with the standard Objective-C serialization ecosystem — Objective-C @interface headers with @property declarations. No unusual dependencies required.
