Answer: 
```
cd platforms/ios

pod repo update

pod install

```

explanation: you need to navigate in to the ios platform directory where the .podfile exists, and then run the commands "pod repo update" and then "pod install"
**Updated answer**: I faced this again at an update from 3.0.7 (or later)

I fixed it with the following steps: 

1. **Adding a *notification extension*** as described in the `react-native-onesignal` docs.
2. **Remove the old imports** and code from `AppDelegate.m`

**Removed lines**:

```
#import <OneSignal/OneSignal.h>
....
 (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
{
  if([self pushAvailable]) {
    [RCTPushNotificationManager didReceiveRemoteNotification:notification];
    [RCTOneSignal didReceiveRemoteNotification:notification];
 }
}

```

All the steps are described here:

**Old answer**

For react-native-onesignal versions <= 3.0.7

1. Add OneSignal.framework that is in
../node\_modules/react-native-onesignal/ios/Frameworks/OneSignal.framework
in YourProject > Build Phases > Link Binary With Libraries
2. Add "$(SRCROOT)/../node\_modules/react-native-onesignal/ios/Frameworks" in
YourProject > Build Settings > Framework Search Paths

Run clean build before build.
