Language overview
Objective-C programming language
Objective-C is an object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language supported by Apple for macOS, iOS, and their respective application programming interfaces (APIs), Cocoa and Cocoa Touch, until the introduction of Swift. The language was used for building apps for iOS and macOS, as well as being the primary language for NeXTSTEP, from which macOS and iOS derive.

Choosing the right tool
How is this different from the Objective-C Code Checker?
The Objective-C Code Checker is diagnostic-first: it gives you a list of issues to work through, with corrected code as a secondary section. The Code Fixer is solution-first: it leads with the complete working code, shown as a diff against your original, and briefly explains what changed. Use the Objective-C Code Checker when you want a fuller issue-by-issue review.

How do I fix broken Objective_C code using CodeConvert AI?
Paste your broken or non-working Objective_C code into the input box, optionally add the error message or traceback you're seeing, and click Fix Code. Our AI will diagnose the problem and return the complete, corrected Objective_C code along with a summary of what changed.
What kinds of Objective_C problems can this tool fix?
This tool can fix a wide range of problems in Objective_C code, including syntax errors, logic errors, off-by-one bugs, null/undefined access, type mismatches, and the specific error or exception in a traceback you paste in.
Should I include the error message when fixing Objective_C code?
It's optional, but recommended. If you have an error message or traceback from running the Objective_C code, pasting it into the "Error message / traceback" box helps the AI pinpoint the exact cause instead of guessing, which usually produces a more accurate fix.
