Xcode: view references for a variable?

I am new to Xcode. I am not sure if there is a way to view a variable's references just like "Find all references" in Visual Studio by right click on a var?

For example, in my .h file, I would like to know or view all the references for property isSet:

@interface MyInterface {
   ...
   BOOL isSet; // view all references to this var?
   ...
}

Find selected symbol in workspace is what you need

  • right click on the method/property -> Find -> Find selected symbol in workspace
  • focus the property/method and press ⇧ + ⌃ + ⌘ + F (or you can have a custom one)

Does basically the same search as Refactor -> Rename does

Update for XCode 12: right click on definition -> Show code actions -> Callers...

This will show every place in the project where this method or property is referenced.

You're conflating two different things in your question: finding references to a variable, and finding references to a property. Finding references to a property can be done via the 'Related Files' menu, as described in my answer here: https://stackoverflow.com/a/17931752/1709587

Finding references to a variable can be sort-of done via 'Find Navigator' tab of the Navigator. (That's the magnifying-glass-icon tab of the left side menu.) Go to Find -> References -> Matching and type in the variable you're looking for. That said, I can't see that this is particularly useful, because:

  1. It will match all occurrences of a variable with that name, even if they're unrelated to the particular variable you're looking for.
  2. Why would you ever need this? You shouldn't generally be using public member variables (use properties instead), so 99% of the time, all references to the variable you're interested in will be within the file in which it is declared. Just using cmd+f and doing a simple text search within that file has always sufficed for me, and I've never felt the need to bring out heavier machinery. If you hit a couple of comments while doing this, who cares?

If you truly, truly do need the functionality you're asking for, and neither the 'Related Files' menu, Find -> References, nor a simple text search will do, then your only options are to use some third party tool like AppCode or the (cumbersome, slow) 'refactor' hack proposed by Karim.

I was looking for similar option. I do not know why XCode did not included that. But there is a work around I use until Apple give that option in XCode.

Try this in the source code (.m) file, 

Select the symbol, right click -> Refactor -> Rename 
-> Give a name whatever you wish, then press Preview.

Now you can find all the references. Now you can Cancel it or do not rename it. :)

Beside Xcode, there is AppCode IDE from JetBrains. And in AppCode it is easily possible, just select Search --> Find Usages.

Try using: Find in project -> As symbol context menu. Sometimes you may want to search as definition instead.
