字典中不带括号的 Swift 键值

Question

When I try to print/assign key/value data in Swift, brackets surrounding the data. I want to hide/cut the brackets.

Have tested in Swift with Code below.

func listenForChanges() {
        let db = Firestore.firestore()
        db.collection("Block").document("Test")
            .addSnapshotListener { documentSnapshot, error in
                guard let document = documentSnapshot else {
                    print("Error fetching document: \(error!)")
                    return
                }
                guard let data = document.data()?.values else {
                    print("Document data was empty.")
                    return
                }

                self.syncText.text = "\(data)"
        }
}

Current result is -> [value]

Expected result should be -> value

Any suggestion to hide the brackets?

As @Scriptable suggested it works with the following:

self.syncText.text = "\(data.first!)"

Thank you!
