Add this post install script to your Podfile:

post_install do |installer|
    ## Fix for XCode 12.5
    find_and_replace("Pods/FBRetainCycleDetector/FBRetainCycleDetector/Layout/Classes/FBClassStrongLayout.mm",
      "layoutCache[currentClass] = ivars;", "layoutCache[(id<NSCopying>)currentClass] = ivars;")
end

End of the Podfile add this function:

def find_and_replace(dir, findstr, replacestr)
  Dir[dir].each do |name|
      text = File.read(name)
      replace = text.gsub(findstr,replacestr)
      if text != replace
          puts "Fix: " + name
          File.open(name, "w") { |file| file.puts replace }
          STDOUT.flush
      end
  end
  Dir[dir + '*/'].each(&method(:find_and_replace))

Thank you for the report!
layoutCache[(id)currentClass] = ivars;
appears to be the correct fix and it actually appears in the latest code.
https://github.com/facebook/FBRetainCycleDetector/blob/master/FBRetainCycleDetector/Layout/Classes/FBClassStrongLayout.mm#L201
Did you perhaps forget to pull?

The latest code has not pushed to CocoaPods . Current version on CocoaPods is 0.1.4 without the fix .

This file is read only, as all Pod source files are. Just add write permissions to yourself on the file.
But at that point if you are the only one working on this project, you can just modify it by hand.

Add require:

require "fileutils"

Modify the code:

def find_and_replace(dir, findstr, replacestr)
  Dir[dir].each do |name|
      FileUtils.chmod("+w", name) #add
      text = File.read(name)
      replace = text.gsub(findstr,replacestr)
      if text != replace
          puts "Fix: " + name

          STDOUT.flush
