If your application is targeting iOS versions **prior to iOS 12.2** and your application **does not already contain any Swift code**, then you need to make sure Xcode bundles Swift standard libraries with your application distribution. To to so, open your target Build Settings and enable `Always Embed Swift Standard Libraries`:

 The PSPDFKit React Native iOS Wrapper maps most configuration options available in `PSPDFConfiguration` from JSON. Please refer to [`RCTConvert+PSPDFConfiguration.m`](./ios/RCTPSPDFKit/Converters/RCTConvert+PSPDFConfiguration.m#L267) for the complete list and for the exact naming of enum values.

+#### Process Annotations
+
+The PSPDFKit React Native Wrapper allows you to create a new document with processed (embedded, flattenned, removed, or printed) annotations on Android and iOS using the `PSPDFKit.processAnnotations(annotationChange, annotationType, sourceDocumentPath, processedDocumentPath)` function. In the snippet below, we add a button which flattens all the annotations of the document from the currently displayed `PSPDFKitView` in a newly processed PDF file:
+
+```javascript
+<View>
+  <Button
+    onPress={async () => {
+      const processedDocumentPath =
+        RNFS.DocumentDirectoryPath + "/flattened.pdf";
+      // Delete the processed document if it already exists.
+      RNFS.exists(processedDocumentPath)
+        .then(exists => {
+          if (exists) {
+            RNFS.unlink(processedDocumentPath);

+                  } else {
