THIS WEEK'S BLOG POST

​Swift Tutorials: Learn Swift with Easy-to-Follow Code Examples​

Since 2015, I've published over 250 articles. Yet, a good starting point didn't exist, and outside of search engine results, it's pretty hard to discover all the valuable content I've written. Therefore, I used this holiday week to publish an entry article for both beginner and intermediate articles. I've listed my must-read articles, so even if you're experienced, there's much to discover!

​Creating a SwiftUI text view with tappable links​

I realize I run into this every now and then: how to add links into SwiftUI text? There are different ways, and I know that, but I always struggle to pick the right solution. Hopefully, that’s not happening anymore with this article by Daniel Saidi.

​Never Miss a Localized String Value Again​

When I first noticed this article, I expected some kind of launch argument that would duplicate words or turn them into red. The opposite is true and the solution is actually quite interesting!

QUESTION OF THE WEEK

“
How do you prevent in-app subscriptions from ending due to billing issues?
— Anonymous

This is a great question and something that's solved better on the web than in apps. As app developers, we're required to built custom solutions to get notified of user billing issues and email users accordingly.

Tools like RevenueCat offer webhooks that you can use to get a signal when a user subscription status changes to in_grace_period or in_billing_retry. You can use this status in-app to show an alert to inform users that their subscription might end soon if they don't fix their billing settings.

For RocketSim, I decided to go one step further. I've connected RevenueCat to Kit, and use an email sequence to inform users via email about their billing issues. You can use this deeplink to let users dive into their billing settings: https://apps.apple.com/account/billing for a higher chance of solving.

Altogether, it's these small improvements that will increase your subscription retention, revenue, and LTV.
