CONQUERING REACTIVESWIFT: PRIMITIVES

iPhone app developer

Winklix is an app development company that does most of their iOS development using Reactive Swift. There are two approaches of solving a problem in swift. First one is the imperative way and second one is the functional reactive way. Reactive Swift is taking leaps and bounds in today’s world. It is getting more and more prevalent with each passing day. Let us try to understand what is all the fuzz about?

 

Basic building blocks of Reactive Swift

One of the best ways to manage the complexity of user interface is through reactive programming. Reactive Swift creators were focused to creating a language which is declarative, composable and flexible. The paramount feature of the Reactive Swift is that it is an amalgamation of streams, transformation and bindings. Streams are a very familiar data structure through which you can send anything. It is decisive to listen for the stuff, otherwise you may miss it. Using the transformation, you can basically map one type of array into another type of required array. Binding is a third ingredient of Reactive Swift. Through bindings, you can bind the stuffs to things.

Reactive Swift has a very basic building block structure given below which will assist you to write code in functional reactive way. These key building blocks are categorized in the following way.

Source

Our main focus is on the rapid changes over time rather than a particular state in time. These all primitive blocks are categorized under the Source category in reactive programming. Source comprises of Event, Signal, Signal Producer and Action. These key building blocks are accountable for the proliferation and occurrence of the changes in time.

  1. Event

An Event is the occurrence of something. Events are the centrepiece of communication. An Event might be occurrence of an error, press of a button or receive of any information from an API. Events are of following four types

  • Value: This event offers a value from the source.
  • Failed: This event means that an error has occurred before the completion of a signal.
  • Completed: This event means that the signal has completed successfully and no more signals will be sent from the source.
  • Interrupted: This event means that the signal has been interrupted because of the cancellation. This means that the operation was neither successful nor unsuccessful.
  1. Signal

Signals represent event streams that are in progress like user input, notifications etc. When the user gets the data, events are sent through signals. This is pushed out to all the observers due to which all observers can view the events at same time.

  1. Signal Producer

Signal Producer creates signals and represents tasks and operations like network requests etc. Signal Produces is considered to be cold as it needs to be initiated while Signal is considered as warm because it does not need to be initiated.

  1. Action

Actions are responsible for doing work when executed with an input like click of a button. It generates output values like zero while execution. Actions can also be disabled on property which will disable any controls associated with the action.

  1. Property

Property is used to store a value. If there is any change in the value, it automatically notifies. The current value can be accessed from the value getter. The current value is send by the producer getter through signal producer.

Consumer

The basic blocks in this category listens and perform according to the events generated and sent by source primitives. Consumer category has two sub-categories.

  1. Observer

It captures the work that needs to be performed in reply of the emitted events from the source. An observer takes event as an input.

  1. Mutable Property

Just like Property, it is also used to store the value. But it is different from the property as it can be muted directly. It has the ability to update its value according to the values received by signal.

Operators

 

Operators are the functions that transform signal and signal producer. These are composable primitives that work with event streams. These operators can be used for transformation, performing side-effects, flatten, combine etc.

Scope

These primitives are used for determining the interaction time between the consumer and source. It has the following two sub categories

  1. Disposable 

Disposable enables the user to manage the memory and cancellation of signal. When we start the signal Producer, we get a disposable which can be used to cancel the started work.

  1. Lifetime

It determines the longevity of an object like we want to observe a notification till the UI component is on the screen.  

The Flow

The complete flow of how the primitives complete the job is explained below

Step 1: Defining a Signal

let signal: Signal<String?, NoError>

Step 2: Transforming a Signal

As we can see that in the first step, we get an optional string. Then we need to transform the nil string to empty string and transform it one more time to give Boolean values. We have used skipNil to ignore nil strings here

let transformedSignal = signal

.map { text in

text ?? “”  

}.map { text in

text.characters.count > 10

}

Step 3: Observing Signal

We observed that the setting isEnabled on the screen. We will start observing the transformed signal via observe primitive.

let observer =

Signal<Bool, NoError>.Observer(value: { value in

button.isEnabled = value

})

let disposable = transformedSignal.observe(observer)

Step 4: Stop observing a signal

Observe primitive returns a instance which can be used to stop signal observing

disposable.dispose()

Conclusion

This is how the different basic building blocks or primitives are used to write code in a functional reactive way. Winklix is iPhone app development company who create app that get’s featured in App Store . In case you are willing to have your app developed by us , you can contact us .

HOW BLOCKCHAIN IS OPTIMIZING INVESTMENT BANKING COSTS

 

Blockchain technology in investing banking

 

Data storage is one of the most essential components of banks. Database plays a very key role in the proper functioning of the investing banks. Banks need database to store the valuable information of the customers which is needed by them to provide valuable services like transactions to the customers.

Banks database are huge and multiple due to which managing the database of the banks regarding people information is not an easy task. It can be really troublesome and hectic task. The database must be really secure and protective because it store very confidential and private information and any disclosure of customer’s information can create lot of troubles.

Blockchain technology is the answer to all the above problems. It ensures that the transactions are smooth and database are secured and protected. This highly secured access system help in better management of the bank activities and tasks. It provides one platform to access the required data.

According to a report, Blockchain has really cut down the banking cost making them more profitable and saving the cost by up to 30%. It has completely revolutionized the way investing banking is done. The Blockchain investments will increase from $75 million in 2015 to an overwhelming $400 million in 2020.Due to this revolution; different parts of bank databases are connected together which has made the whole banking process very convenient and cost-effective.

Reporting costs are much lower and transparency in data optimization is ensured

 

One of the best features of Blockchain in banks is that it provides a very level of transparency in the financial reports. As we all know that Blockchain is the only source of information, so same information is shared to the authorities, customers and clients at the same time. Due to this unique and one access, tremendous amount of transparency is there in the financial reports.

This is the reason why the verification of the data is much convenient and simple with the help of Blockchain. That is exactly how the banks are able to generate huge amount of reports without much investing on the collection and gathering of the customer’s data.

Reduced Processing cost and enhanced operations efficiency

 

It is important to note that the Blockchain provides a centralized way of storing the information. Information related to the customer and connection with the client is available from a single source. Multiple branches of the bank can use the single source to obtain the information. This reduces lot of operational cost which improves the efficiency level of bank.

As the database is centralized, processing costs are reduced as very less effort is required to access the information. Due to this Blockchain, the digital identity of an individual can be managed efficiently. This is how Blockchain is having a tremendous impact on the banking cost.

Compliance costs are highly reduced

 

In the older days, it was quite cumbersome for the banks to communicate the information of the customers to the counterparties. It was a very difficult task and huge amount of revenue needs to be spent on it. To make it possible, banks have to audit the information again and again to ensure the compliancy.

But with the coming of the Blockchain in the banking investing system, it has makes this task a lot easier. A centralized database is sufficient to audit the transactions. You don’t have to do audit again and again so lot of time is saved. It has brought transparency in the system which has resulted in the building of trust among people and due to this transparency; the whole process is visible to all the authorities. This has reduced the compliance cost by 50%.

The other benefits of how Blockchain affecting investment banking costs

 

Banking system requires a lot of functions to be performed like investigations, clearance, trade support, settlement, clearance etc. To get these functions performed, it is required that the right information is available at the right time because the banks have to analyse, gather and confirm the data before taking any decisions. That is the how why Blockchain database system has made the functioning of the bank so smooth and convenient. In the future, this Blockchain technology is going to rule the banking world as it has made transactions secure and augmented the efficiency. Blockchain has truly optimised the investment banking costs.
