SKError.Code.unknown

Nothing is more frustrating than an error code that isn’t helpful. Such is the case with Apple StoreKit’s SKError.Code enumeration’s unknown case. This is a catch-all error code if one of the long list of error codes doesn’t match.

Apple suggests two things if this error is encountered:

• Development: Create a use a new App Store Connect test user
• Production: Sign-out then back in to App Store

There are likely other undocumented reasons why this error might get thrown. If neither of the potential resolutions above do not fix the issue, please reach out and we’ll try to help.

A Final Word About StoreKit

If you are a Nami customer, you generally don’t need to worry about StoreKit implementation details since we take care of it for you. However, the Nami SDK does surface certain StoreKit messages for debugging purposes depending on the log level.

If you received the following message from the Google Play Console, you are not alone:

We’ve detected this app uses an unsupported version of play billing

Chances are your app is on an unsupported version of Play Billing. Google announced that by November 1, 2021 all new apps and updates to existing apps must use Billing Library version 3 or newer.

Check import dependencies for Play Billing Library version 3 or newer

Check your project’s build.gradle file. Apps must import Play Billing Library version 3.0.0 or higher. Please note, these dependencies would only show up for APKs that require the permission com.android.vending.BILLING.

Make sure AndroidManifest.xml contains the Play Billing version entry

If you are on the latest Play Billing Library but still see the message, you will need to check your AndroidManifest.xml. Ensure it contains an entry for com.google.android.play.billingclient.version

According to Google, the entry might not be present if the manifest attribute is being dropped during manifest merging. You can check your manifest merge settings.

Upgrading from Play Billing Library V1/AIDL

If you are on Play Billing Library V1 / AIDL, Google has a migration guide for upgrading to Play Billing Library version 3. In short, there are major code changes you will need to make to your project.

Not your last “unsupported version of play billing” message

Google regularly introduces new functionality and APIs as part of the Play Billing Library. In fact, upgrading to version 3 won’t mean you’ll never again see the message about an unsupported version of play billing.

You can future proof your Play Billing implementation. With Nami, we manage the Play Billing implementation and you get to focus on your app. No server-side code is required and the client SDK is extremely easy to adopt. Our generous free tier provides reasonable limits and lots of features not found in homegrown implementations.

The Great Resignation has seen 33 million Americans leave their jobs since the Spring of 2021. While the global pandemic was a catalyst, it’s not what gave so many people the confidence to make the leap. Do you have an idea to sell an app?

It’s never been a better time to be a solopreneur. All you have to do is explore communities such as #buildinpublic on Twitter to see the diversity of products people are building.

There are plenty of great opportunities to make money online in 2022. Here’s just three:

1. Make and Sell an App

It’s never been easier to learn how to make an app. People from all walks of life are learning how to get started with programming using Swift Playgrounds from Apple.

Want to learn how to design and code your first mobile app? Check out the more than 240 tutorials from Design+Code.

Once you make an app, it’s time to make money. In fact, it’s never been easier to make money by collecting in-app payments through the Apple Store or Google Play. Nami provides a simple toolkit to sell your app like additional features, content, or even tips. Payments can be through one-time purchases or recurring subscriptions.

You can sell your app another way, too! Services like Flippa provide a market place for buying and selling apps. The more app revenue, the higher the price.

2. Build a SaaS app with No Code

In addition to a mobile app, you can build a SaaS (software as a service) application. So-called micro-SaaS apps are easier than ever to build no code tools like Bubble. Once built, it’s easier than ever to get feedback and find your first customers.

Communities like Indie Hackers and Product Hunt provide a great jumping off point. Get the word out by sharing what you are doing and asking for feedback.

Once you’ve generated some revenue, sell the app on Flippa or for a nice premium on MicroAcquire if your monthly recurring revenue (MRR) supports it.

3. Create and Publish an Information Product

Another way to make money online is to share your knowledge with others. Paid info products have become incredibly popular. From ebooks to video courses, these come in many formats.

There are so many of these types of products. Some offered for a one time fee. Others through a membership.

Just a few examples:

• Learning the Figma design tool from a course on Udemy
• Materials for mastering cold emails or becoming a creator sold on Gumroad
• Learn about search engine optimization (SEO) from Moz Academy

Anyone Can Sell an App & Make Money Online

We covered only three of the ways people are making money online. There are so many more. All you need to do is figure out what your niche is and have the courage to get started. Happy selling!
