I understand that The text property of UILabel is optional, I tried adding an else but i'm not sure what else to add.

productData.product.productName is me getting the name of the product from the database

 if var pName = productData.product.productName //error
 self.productName.text = pName
 

@IBOutlet weak var pName: UILabel!

Initializer for conditional binding must have Optional type, not 'String' is the error I get, It was working I think im not sure where its gone wrong

  The error is pretty clear. productData.product.productName is not optional. Why have you tried to unwrap it?

It states that the use of if condition is unnecessary, because the 'productName' is not optional.

You can directly add the value to your label.

self.productName.text = productData.product.productName //Product name is not optional

Optional chaining is used when you try to get a optional value.
For example, if you want to get the text of label then you'll require if condition.

if var text = self.productName.text //Text in label is optional
 print(text)

  Assigning the 'productData.product.productName' to the label will update the 'productName' to it.

It seems like the compiler is complaining that productData.product.productName is NOT an Optional. The if var name = ____ construct only works on Optionals.

If you are testing for a non-empty String, you may want to check the count or isEmpty instead.
