i ran similar issue when wrote own content blocker. when create content-blocker extension create json file extension reads from. now, important part extension reads file located in extension's bundle directory.
from can see writing json file in main app bundle , reloading content blocker. content blocker looks @ file in it's own directory (again, seperate main bundle directory) , loads json file.
to resolve this, need write file changes json file located in extensions bundle directory.
here's example:
let groupurl: nsurl = filemanager.containerurlforsecurityapplicationgroupidentifier("group.com.mygroup")! if let path = nsurl(string: "blockerlist.json", relativetourl: groupurl) { // write json data path here sfcontentblockermanager.reloadcontentblockerwithidentifier("com.my.extension.identifier", completionhandler: nil) } another important thing note you'll have request special permissons read , write extension's bundle.
