+# deleteAllMindfulSessions
+
+Delete all mindful sessions from HealthKit.
+
+`deleteAllMindfulSessions` accepts a callback:
+
+Example usage:
+
+```javascript
+AppleHealthKit.deleteAllMindfulSessions((err: string, result: number) => {
+  if (err) {
+    console.log(err)
+    return
+  }
+  // sample successfully deleted
+  console.log(result)
+})
+```
+
+Example output (if 20 objects are deleted):
+
+```json
+20
+```
