Integration of Apple Pay-Swift

Apple Pay is provided by Apple to get the amount from end-user for their order in an easy, robust, efficient manner. Its integration is easy for the developer too.

Before the Integration of Apple Pay in our iOS mobile application, we need to understand the user guidelines of Apple.

Why did we need to integrate?
When we get a requirement to get the money from the user they purchased from our Mobile application then we need to add the payment gateway to our app so that we can collect the money from the user’s bank account to our merchant account. Once we know that we need to integrate the payment gate to get this done then the next question is what we are sold to the user or what user going to be purchase from our Mobile Application. It may be a physical purchase or it may be a Digital purchase. If it’s a physical purchase then we can collect the amount using any 3rd party payment gateways as per the project requirement, documentation, or client concern. But, If it’s a Digital purchase then we need to integrate In-App purchase as per the Apple guidelines. In-App purchase is a different story we will come back to this in another story. Till now we understand that we need to integrate the 3rd party payment gateway If our mobile application collects the money for the Physical purchase. Now the real requirement of the Apple Pay integration starts. Apple says that if you integrate any 3rd party payment gateway to get the money from the user for their physical purchase then you need to integrate the Apple Pay in your app as an option to the user with the 3rd party payment gateway.

Note: Some 3rd party payment gateways already provide Apple pay with their payment gateway we need to just configure it as per their guidelines.
