Function jumps the else statement after checkin if statement Swift

I have a function saveOrders() that checks if snapshot from firebase corresponds to a record already been saved to CoreData by comparing orderIdof the saved orders against the one that get passed from snapshot in function's closure. If it matches it returns, otherwise in the elsestatement creates a new record to CoreData depending on iOS version. Weirdly enough it worked yesterday, but today it jumps directly the else statement when ids don't match. Today I only added the commented out part. Can you spot where it got broken? Here's the code:

    static func saveOrder(orderId: String, orderDate: String, customerName: String, orderPrice: String, itemsIdList: String, itemsList: String) throws {
        let context = CoreData.databaseContext
        let userRequest: NSFetchRequest<User> = User.fetchRequest()
        do {
            let userFetch = try context.fetch(userRequest)
            print("@@@@@@@@@@@@@@@@@@       fetching user")
            for userValue in userFetch {
                if userValue.name == UserDetails.fullName {
                    print("User is: \(userValue.name!)")  //correct
                    let orderRequest: NSFetchRequest<Order> = Order.fetchRequest()
                    let predicate = NSPredicate(format: "orderId == %@", orderId)
                    orderRequest.predicate = predicate
//                    orderRequest.fetchLimit = 1
                    do{
                        let orderFetch = try context.fetch(orderRequest)
//                        if orderFetch.count == 0 {
                        for order in orderFetch {
                            if order.orderId == orderId {
                                print("Order is already saved")
                                return
                            } else {
                                    print("@@@@@@@@@@@@    order is new")
                                    if #available(iOS 10.0, *) {
                                        let order = Order(context: context)
                                        order.user?.name = userValue.name!
                                        order.orderId = orderId
                                        order.orderDate = orderDate
                                        order.customerName = customerName
