All views have a natural position inside your hierarchy, but the offset() modifier lets you move them relative to that natural position. This is particularly useful inside ZStack , where it lets you control how views should overlap.

The zstack alignment is top leading so from my understanding every child (hstack's) should be aligned to the top leading edge of the zstack. This is the case when I add the fisrt hstack. It aligns to the top leading edge as expected. However as soon as the second hstack is added the e first hstack centers in the zstack view. An easy way to get animation into your SwiftUI Views is to place code inside a withAnimation block. ... (0,0), but due to its position on the screen that View’s global position may differ from this. Thankfully, SwiftUI also ships with a Group type, which lets us treat a set of views as a group — without affecting their layout, drawing, or position within our overall view hierarchy. Using that type, we can group our two labels together, and then apply our set of modifiers to both of them at the same time:

ViewModifiers play a significant role in SwiftUI. Most of the functions called on a View are ViewModifiers. It is the primary way of modifying the view instance in SwiftUI. In this post, we will take a look at some ready to use ViewModifiers, and then we will build our own custom ViewModifier. Fortunately we can write one ourselves by leveraging SwiftUI’s view builder system. This means writing a type that must be created using a row and column count, plus a closure it can run to retrieve the views for a given cell in the grid.
