How can I disable ARC for a single file in a proje

Question

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?

Note: if you want to disable ARC for many files, you have to:

1. open "Build phases" -> "Compile sources"
2. select files with "left_mouse" + "cmd" (for separated files) or + "shift" (for grouped files - select first and last)
3. press "enter"
4. paste -fno-objc-arc
5. press "enter" again
6. profit!

Answer 3

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.

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 :

If you're using Unity, you don't need to change this in Xcode, you can apply a compile flag in the metadata for the specific file(s), right inside Unity. Just select them in the Project panel, and apply from the Inspector panel. This is essential if you plan on using Cloud Build.

It is very simple way to make individual file non-arc.

Follow below steps :

Disable ARC on individual file:

1. Select desired files at Target/Build Phases/Compile Sources in Xcode

2. Select .m file which you want make it NON-ARC PRESS ENTER Type -fno-objc-arc

Non ARC file to ARC project flag : -fno-objc-arc

ARC file to non ARC project flag : -fobjc-arc
