I’ve been experimenting with iOS 26’s new icon customization features. I’ve noticed that many popular apps are already using multiple icons, and it seems iOS 26 allows custom icons through Apple’s Icon Composer.
I tried adding a lot of icons in my app, but it kept crashing… crash after crash. To avoid this, I switched to using Image in SwiftUI to display icons, which works fine, but I really want to properly integrate multiple app icons with Icon Composer like the big apps do.
Here my screenshot with image icon.

If anyone has experience with this: How do you build a SwiftUI app that supports many custom icons using the iOS 26 icon composer without crashing? Any guidance, examples, or best practices would be super helpful.
Thanks in advance!
NOTE: THIS IS TALK ABOUT ONLY ICON COMPOSER! How can I add many icon composer! Whenever, I add icon composer, it won’t change icon, and image is not display… I have seen some app form other App Store, has import icon composer, my question how can I import many icon composer without Image needs! Look this when I added icon composer icon files, then this is my answer to whoever closed my question.
