Removing duplicates from an array can quickly become a performance challenge when your array has thousands of items. In this week's article, we discuss performant options to efficiently get unique values, including an extension to filter by a specific property.
Are you tired of Ruby and Fastlane installation issues? There's got to be a better way! Discover Codemagic open-source CLI tools. It is not a drop-in replacement for all of what Fastlane does (screenshots for example), but we use it at Codemagci to build and publish iOS and Android apps, also versioning and device provisioning.

SWIFT EVOLUTION
An overview of last week's Swift Proposal state changes. Check them out when they're in review, as it's your opportunity to influence the direction of Swift's future.
No changes! It seems that they're keeping the changes for WWDC ;-)
What is the best way to optimize my onboarding funnel?
You're promoting your app on socials, you've optimized your App Store landing page, and you've done everything to get that user to install your app. You've might even paid for advertising!
The user starts using your app, but where does the user end? Will they stick? Or do they stop using your app within a minute after using it?
The onboarding funnel of your app is just as important as all the steps before a user even installs. The higher the percentage of users ending up sticking to your app, the larger your revenue potentially becomes. You'll have more upsell opportunities for both your paywall as your app's added value.
I'm constantly revisiting RocketSim's onboarding as I'm learning from my Amplitude statistics. Even recently, I realized it might not be clear to users that you can use RocketSim for free as well. I decided to add an NSAlert which shows up when closing the paywall window. The hypotheses I've had is that users would quit the app completely after seeing the paywall, thinking it's a paid-only app.
The result looks as follows:

The initial three steps show similar results, but the drop-off after the paywall is much lower for my latest release. 66% instead of 54% of the users end up seeing RocketSim's Side Window, which is the key action for my app:
If users see the side window, they're most likely going to use and experience the app.
If they experience the app, they're most likely sticking
If they're sticking, they're more likely to eventually convert
In other words, I've probably increased my revenue in the long run! All by focusing on a single step of my onboarding funnel.
