LiveActivities will be degraded in iOS 18. On iOS 17 I could update my LiveActivity around every second (through a connected Bluetooth device). With beta 7 it’s between 5-15 seconds 😫 release notes say they fixed excessive battery usage of Text in LiveActivities. FB14936793

Last update was a blast! 💥 ASO tip: don’t use all 100 keyword characters. The AppStore algorithm puts more relevance on your other keywords then. Thanks @arielmichaeli for showing me that!

Sometimes I really question the people who are working at the Apple app review team. The person on the other side says my in-app event deep link doesn’t work and he provides me a screenshot from the Mac 😵‍💫 (my app is iOS only)

It’s that time of the year. A reviewer wants to see a video of my app in action. My way to deal with it - remove the build and resubmit it and hope for a less nosy reviewer.

Lessons learned: Don't put image data into CoreData. The more images you save, the slower your database access gets. Put the images on disk and save a link to them in CD. Then load the images async and update the UI when loaded. My app feels so much better now 🚀

Look how cute this little app is! It’s not – it’s a machine to extract as many $ as possible from you. There are tons of gambling elements in it that make the weaker ones addicted. It’s also a big part of Apples “Services Revenue”.
