Taming SwiftUI’s ForEach Beast with a SectionItem Magic Trick
Ever tried mixing different types of content into one list in SwiftUI and felt like you were juggling flaming swords? I recently ran into this conundrum in a project where I needed to display a blend of distinct content pieces in a single scroll view. SwiftUI’s ForEach is a bit of a stickler—it demands that every item be of one uniform, uniquely identifiable type.
