iOS App Extensions: Data Sharing

App extensions are permeating more and more into our daily job. But some nuances of the way they work are still not so obvious. In this post I try to investigate different ways to share data between an app and its extension.

Bundle

var bundle = Bundle.main
        if bundle.bundleURL.pathExtension == "appex" {
            // Peel off two directory levels - MY_APP.app/PlugIns/MY_APP_EXTENSION.appex
            let url = bundle.bundleURL.deletingLastPathComponent().deletingLastPathComponent()
            if let otherBundle = Bundle(url: url) {
                bundle = otherBundle
                guard let dvc = UIStoryboard(name: "Main", bundle: bundle).instantiateViewController(withIdentifier: "TestViewController") as? TestViewController else { return }
                self.navigationController?.pushViewController(dvc, animated: true)
            }
        }
        let appDisplayName = bundle.object(forInfoDictionaryKey: "CFBundleDisplayName")
