objective-c - remove - xcode project arc




How can I disable ARC for a single file in a project? (12)

  1. Select Xcode project
  2. Go to targets
  3. Select the Build phases section
  4. Inside the build phases section select the compile sources.
  5. Select the file which you do not want to disable ARC and add -fno-objc-arc

I am using ARC successfully in my project. However, I have encountered a few files (e.g., in unit tests and mock objects) where the rules of ARC are a little more fragile right now. I recall hearing that there was a way to disable ARC on a per-file basis, though I have been unable to find this option.

Is this possible? How do I disable ARC on a per-file basis?


  1. select project -> targets -> build phases -> compiler sources
  2. select file -> compiler flags
  3. add -fno-objc-arc

Add flag “-fno-objc-arc”.

Simple follow steps : App>Targets>Build Phases>Compile Sources> add flag after class “-fno-objc-arc”


Following Step to to enable disable ARC

Select Xcode project Go to targets Select the Build phases section Inside the build phases section select the compile sources. Select the file which you do not want to disable ARC and add -fno-objc-arc


GO to App -> then Targets -> Build Phases -> Compile Source

Now, Select the file in which you want to disable ARC

paste this snippet "-fno-objc-arc" After pasting press ENTER

in each file where you want to disable ARC.


I think all the other answers are explaining how to disable MRC(Manual Reference Count) and enabling ARC(Automatic Reference Count). To Use MRC(Manual Reference Count) i.e. Disabling ARC(Automatic Reference Count) on MULTIPLE files:

  1. Select desired files at Target/Build Phases/Compile Sources in Xcode
  2. PRESS ENTER
  3. Type -fobjc-arc
  4. Press Enter or Done

It is possible to disable ARC (Automatic Reference Counting) for particular file in Xcode.

Select Target -> Build Phases -> Compile Sources -> Select File (double click) -> Add "-fno-objc-arc" to pop-up window.

I had encountered this situation in using "Reachibility" files.

This is shown in below figure :


It is possible to disable ARC for individual files by adding the -fno-objc-arc compiler flag for those files.

You add compiler flags in Targets -> Build Phases -> Compile Sources. You have to double click on the right column of the row under Compiler Flags. You can also add it to multiple files by holding the cmd button to select the files and then pressing enter to bring up the flag edit box. (Note that editing multiple files will overwrite any flags that it may already have.)

I created a sample project that has an example: https://github.com/jaminguy/NoArc

See this answer for more info: Disable Automatic Reference Counting for Some Files


Just use the -fno-objc-arc flag in Build Phases>Compile Sources infront of files to whom you dont want ARC to be apply.


Just use the -fno-objc-arc flag in Build Phases>Compile Sources


Please Just follow the screenshot and enter -fno-objc-arc .


The four Mandatory Step as explained in this video

    //1. Select desired files
    //2. Target/Build Phases/Compile Sources
    //3. Type -fno-objc-arc
    //4. Done
