I am trying to figure out how I can match the Strings which are Firebase UID's in my "data" array with the keys that I am extracting from the firebase call. I need to match the Strings in the "data" array with "key" and then I will be able to manipulate the data how I want.

 var data = [String]()

 Database.database().reference().child("Businesses").observe(.value, with: snapshot in
 guard let allUsers = snapshot.children.allObjects as? [DataSnapshot] else return
 print(allUsers)
 print("Printing all users right here")
 for user in allUsers 
 let key = user.key
 print(key)
 print("Printing the keys right here come and check this out in the print")

 
 )

My try, answer not in this code

 Database.database().reference().child("Businesses").observeSingleEvent(of: .value, with: snapshot in
 self.businessUID = snapshot.value as? NSDictionary
 if let dict = snapshot.value as? NSDictionary 
 for item in dict 
 let json = JSON(item.value)
 let businessUid = json["uid"].stringValue
 for uid in self.data 
 if uid == businessUid 
 Database.database().reference().child("Businesses").observe(.value, with: snapshot in
 guard let allUsers = snapshot.children.allObjects as? [DataSnapshot] else return
 print(allUsers)
 print("Printing all users right here")
 for user in allUsers 
 let key = user.key
 print(key)
 print("Printing the keys right here come and check this out in the print")
 if key == uid 
 print(key)
 print("printing the matching keys here")
 

 
 )
 print(uid)
 print("Printing the uids here")

 Database.database().reference().child("Businesses").child(self.businessessuids).observe(.value, with: snapshot in
 print(snapshot)
 print(self.businessessuids)

 )

 
 
 
 

 )

UPDATE: Found matching values but cannot save

Database.database().reference().child("Businesses").observe(.value, with: snapshot in
 if snapshot.exists() 
 for snapChild in snapshot.children 
 if let user: Dictionary? = (snapChild as! DataSnapshot).value as? [String : AnyObject] 
 let businessUID = user!["uid"] as! String
 for uid in self.data 
 if uid == businessUID 
 let key = uid.jsonKey
 print(key)
 //print(uid)
 print("checking uid's")
 //let name = user.childSnapshot(forPath: "name").value as! String
 let Ref = Database.database().reference().child("testing")
 let saveUID = Ref.child(key).child("their_name")

I've done some changes in snapshot. Though I haven't verify as I don't have any Firebase database setup at my end as yours.

Database.database().reference().child("Businesses").observe(.value, with: snapshot in

 if snapshot.exists() 

 for snapChild in snapshot.children 

 if let user: Dictionary? = (snapChild as! DataSnapshot).value as? [String : AnyObject] 

 debugPrint("User uid: ", user!["uid"] as! String)
 
 
 

 )

Replace your call with above code snippet and let me know if you are still having any issue.

Note: You can also improvisation you all user structure into model for better use.

This works. Great Success!

Database.database().reference().child("Businesses").observe(.value, with: snapshot in
 if snapshot.exists() 
 for snapChild in snapshot.children 
 if let user: Dictionary? = (snapChild as! DataSnapshot).value as? [String : AnyObject] 
 let businessUID = user!["uid"] as! String
 for uid in self.data 
 if uid == businessUID 
 let key = uid.description
 print(key)
 print("checking uid's")
 let Ref = Database.database().reference().child("testing")
 let saveUID = Ref.child(key).child("tested")
 saveUID.setValue("String")
