The term "Digital Nomad" becoming more and more popular in every year within last decade, maybe more visible in last 5 years. It has become well known and accepted as more people shared their nomadic stories on their blogs.

We can say it's more like a lifestyle change than a temporary thing for most people. There is a pattern on the personas accepted this lifestyle. They are working mostly in tech industry, usually creates stuff, standalone or not needing constant collaboration with a team or don't have physical dependencies (sourcing materials etc). People like sysadmins, developers, designers, digital artists...

The term "nomad" explains the lifestyle factor more than being digital because it's all about being location independent. Working from everywhere in any time (often working all the time for entrepreneur versions). It sounds great right? Executing is not necessarily that great :-)

I've been experimenting with different elements of becoming digital nomad in last year period. Each of the following topics below deserves much deeper explanation but I'll summarize them now. I'll write about each one separately later.

Economy models in iOS apps uses In-App purchases become very popular. Lots of developers pick iOS environment because of the flawless payments through iTunes.

If you're planning to have a monetization model in your app, it has to go through Apple system and you have to use in-app purchases. There is no other way to accept payments from your iOS apps. There are pros and cons of using Apple in-app purchases. I'll try to explain some of them.

Biggest con is Apple takes 30% of your sale. And other con is, there are difficulties and grayed areas in integration of in-app purchases to your app and back-end. But the pros makes all even. Because delegating whole payments to Apple is gonna affect your sales because Apple makes it so seamless that it reduces all money related steps to only one confirmation box. So it changes the purchase experience and makes it what it supposed to be. Most of the checkout or payment experiences on web, faces lots of drops because of unnecessary and boring steps like putting your credit card info, trying to give the trust to user that you're a legitimate company, and have legitimate payment system that you will not sell their info out or you won't let hackers to pick your customer info up. All those buying experience changed in iTunes payments. So this is why you shuould want to integrate in-app purchases.

Let's dive in to the integration. You have to use StoreKit which is an interface in iOS that handles all iTunes and payments. I won't talk about objective-c integration of StoreKit, I will just explain what's to do there.

After integration of StoreKit, when user triggers a payment (with tapping a button or something like that) you call StoreKit and iOS shows a confirmation box of your product, price and after that user confirms their iTunes password and StoreKit gives you a "receipt-data" object which is an encoded string holds the receipt details. You don't need to worry about what's in it or how to decode it, because you won't need. You just need that receipt-data to verify and get the all details from Apple. At this point, you need to verify this receipt-data with using their HTTP method.

Some amateur developers doesn't feel the necessity of verifying the receipts they received from StoreKit. But the problem is, there are lot's of easy ways to hack this and jailbroken devices can create fake receipts. So if you don't validate and if you assume you received your payment with whenever you receive a receipt from StoreKit, you may see misuses of your paid content. One other reason to validate is, you might want to (and you should) keep record of your purchases and their statuses (valid or invalid). So I highly recommend you to do a back-end integration to keep track of records and also verification.
