How to Transfer Applications for App Store Small Business Program Members

The App Store Small Business Program offers lowered commission cost with one big caveat: no app transfer. But apps graduating from a “hobby” into a “small business” would definitely involve transferring ownership. Read how to transfer apps without engaging in the app transfer process and losing out on the program’s benefits.

How to Maintain Loading State in Cells

When a table view asks for a cell, often images in the cell isn’t yet available and needs to be fetched from a server – thus the cell gets a placeholder image. But static placeholders doesn’t look as good as animated ones. Unfortunately cell views gets scrolled off and re-used which makes managing animations challenging.

Clean Architecture with VIPER Sample Project for UIKit

Architecting applications to meet today’s challenges and be ready for tomorrow’s problem is not an easy feat. The principles of clean architecture may be sound, but separating the signal from the noise is tough. Here is a sample VIPER project for iOS that you can tinker to learn about the principles of clean architecture.

How to Implement VIPER Clean Architecture in an iOS App

Compartmentalizing functionalities within an app to improve its maintainability is difficult. More so when you’re not well versed with software architectures and other software engineering principles. What if you can confidently structure your app to be resilient and adaptive to change?

How to Pass App Store Review: Guideline 4.2 Design – Minimum functionality

Delivering a “minimum viable product” won’t be viable if your app isn’t going to pass App Store Review. Is your app “good enough” for the App Store? Is it appropriate for the App Store and not better off in the web? Read on to ensure your app pass the gates of App Review.

How to Provide Free Time-Limited Trials in the App Store

Providing “lite” version of apps had been the strategy to provide free trials since the dawn of the App Store. However these reduced-functionality apps fall short on demonstrating its full capabilities, which in itself be ineffective in enticing the user to buy. Fortunately that is no longer the only option available for App Store apps.

How Newbies Should Start Learning iOS User Interface Programming

When you’re just starting out in iOS development, there are so many options in which to place a button. There’s storyboard, auto layout, and even SwiftUI — that’s just scratching the surface. How should someone new to programming the platform chart a learning path?

Modeling In-App Purchases Inventory

There are four types of in-app purchases in Apple’s App Store, with their own unique ways to manage it. The challenge is how to isolate the intricacies of these product types from the rest of the application. Otherwise a move from non-consumable in-app purchase to a subscription type would involve a major rewrite. Learn how to manage an app’s inventory of purchases and get the code base resilient to changes in the business side.

Time-Limited in-App Purchase

What if you need to create a “holiday special” in-app purchase? The item would only be available at a limited period some time in the future. However those who have bought the item would be able to use it beyond the purchase-able period, including restoring purchases should they need it.

I want to let some non-consumable iAP items just be sold during a particular period of time. Also the user who purchased these items still can restore and use it after the time period has elapsed.

Creating time-based in-app purchases (iAP) can be difficult. First all iAPs would need to go through App Review, hence they would need to be available before your app is live. Second is that there’s practically no way for the app to differentiate the app review environment versus the actual production environment – nor does Apple want you to.

But what if I say it can be done? What if you can have a non-consumable iAP, pass it through app review, and only made it for sale only during a specific period in the future? Interested? read on.
