Unknown type name 'RLMSyncCredentials'; did you mean 'RLMCredentials'?

MongoDB Atlas App Services & Realm Realm

#import <Realm/Realm.h>

RLMSyncCredentials *credential = [RLMSyncCredentials credentialsWithUsername:@"sdf"
                                                                            password:@"fsd@123"
                                                                            register:NO];
[RLMSyncUser logInWithCredentials:credential

                             onCompletion:^(RLMSyncUser *user, NSError *error)

I keep getting /sfsf/fsdfsdfds/rel.m:33:5: Unknown type name ‘RLMSyncCredentials’; did you mean ‘RLMCredentials’?

I have in my pods

pod ‘Realm/Headers’ pod ‘Realm’

I also changed credentialswithusername to credentialswithemail same stuff.
