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
