+We’re excited to share that Tolgee now supports the [Apple String Catalog (.xcstrings) format](/platform/formats/apple_xcstrings), a modern localization format for Apple platforms.
+
+<!--truncate-->
+
+This means you can now import and export your localization files in the .xcstrings format, streamlining your workflow for iOS, macOS, and other Apple ecosystem apps.
+
+Apple String Catalog (.xcstrings) is a structured JSON-based format that improves localization handling with features like pluralization and rich metadata. With Tolgee’s support, you can now manage your localized strings seamlessly.
+
+Whether you’re developing apps for iPhone, iPad, macOS, or any Apple platform, simply upload your .xcstrings files to Tolgee, make your edits, and export them back—ready for use in your Xcode projects.
+
+Try it out and let us know what you think! Your feedback helps us improve. Happy localizing!

+
+Apple String Catalog is the latest Apple approach to localization for Apple platforms.
+We recommend using it in favor of XLIFF since this format gives you
+better control over the strings and their translations.
+
+Tolgee supports simple values as well as plural values.
+
+Example of a Stringsdict file:
+```json
+{
+  "sourceLanguage": "en",
+  "version": "1.0",
+  "strings": {
+    "dog_count": {
+      "localizations": {

+              "one": {
+                "stringUnit": {
+                  "state": "translated",
+                  "value": "Já mám jednoho psa."
+                }
+              },
+              "few": {

+                  "value": "Já mám %lld psi."
+                }
+              },
+              "other": {
+                "stringUnit": {
+                  "state": "translated",
+                  "value": "Já mám %lld psů."
+                }
+              }
+            }
+          }
+        }
+      }
+    },
+    "hello": {
+      "en": {
+        "stringUnit": {
+          "state": "translated",
+          "value": "Hello!"
+        }
+      },
+      "localizations": {
+        "cs": {
+          "stringUnit": {
+            "state": "translated",
+            "value": "Ahoj!"
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+We recommend using the semantic keys format as in the examples above. That enables you to change the base values without
+modifying the key and doesn't suggest keeping the keys in sync with the base language translation.
