objective c - How to enable FinderSync Extension in macOS System Preferences

Question

I am integrating FinderSync Extension in my Cocoa Application to show badges in files and folders. Look at the below two scenario:

1. When i run application using FinderSync Extension (like DemoFinderSync) look at the blue popup in the below image, in that case Extension is added in the System Preference with Check mark and called that principal class "FinderSync.m" as well.

2. When i run application using my Application Scheme (like DemoApp) look at the blue popup in the below image, in that case Extension is added in the System Preference but without check mark and that principal class "FinderSync.m" do not call and FinderSync Extension does not work in this case.

Does anybody have an idea how to enable Finder Extension in the System Preference using second scenario?

Answer 1

Non-debug scheme (#if !DEBUG):

system("pluginkit -e use -i com.domain.my-finder-extension");

When running under debugger give path to your extension directly:

NSString *pluginPath = [[[NSBundle mainBundle] builtInPlugInsPath] stringByAppendingPathComponent:@"My Finder Extension.appex"];
NSString *pluginkitString = [NSString stringWithFormat:@"pluginkit -e use -a "%@"", pluginPath];
system([pluginkitString cStringUsingEncoding:NSUTF8StringEncoding]);

Specify this in your applicationDidFinishLaunching method. You should also manually turn this on only once so that if user turned your extension off in the System Preferences you don't turn it on every time your application starts. I set an NSUserDefaults key the first time user launches my app that has the finder sync extension support.
