Cannot convert value of type 'String' to expected argument type '[Any]'

I'm getting the error with the following code in my cellForRowAt method:

self.db.collection("myCollection").document(self.currentUser!).updateData(["myArray":FieldValue.arrayRemove(myArray![indexPath.row])]).

The Cannot convert value of type 'String' to expected argument type '[Any]' error is happening at myArray![indexPath.row]

My function is meant to remove a String value from myArray, so I'm not sure how to resolve this error.

I appreciate any help/guidance!

arrayRemove takes an array of values to be removed, you you'd want to use:

.arrayRemove([myArray![indexPath.row]])

See the added brackets

(https://firebase.google.com/docs/firestore/manage-data/add-data#update_elements_in_an_array)

That being said, be aware that you're force unwrapping multiple things with ! -- be aware that if one of these values is nil, your program will crash.
