# Adaptive SwiftUI toolbars in iOS 27

**[Nil Coalescing](https://daily.dev/sources/nilcoalescing)** · 7 min read · 2 upvotes · 0 comments

## Summary

iOS 27 introduces new SwiftUI toolbar APIs that give developers precise control over adaptive toolbar behavior. Key additions include: `visibilityPriority(_:)` to control which items move to overflow first (with `automatic`, `low`, `high` values and custom relative priorities), `ToolbarOverflowMenu` to permanently place secondary commands in overflow, `topBarPinnedTrailing` placement to anchor an item at the trailing edge regardless of space, and `toolbarMinimizationBehavior(_:for:)` to control scroll-driven navigation bar minimization. Smaller additions include `contentMarginsRemoved()`, `ToolbarPlacement.statusBar` replacing `statusBarHidden(_:)`, and `ForEach`/`EmptyView` conformance to `ToolbarContent` (with `ForEach` back-deploying to iOS 16).

## Questions this post answers

### How do I control which SwiftUI toolbar items move into overflow first on iOS 27?

Apply the visibilityPriority(_:) modifier to a ToolbarItem or ToolbarItemGroup, using automatic, low, or high values. Items with lower priority move into overflow first when space runs out. Custom priorities can be created relative to existing ones, for example a priority lower than .high, when a toolbar needs more than three importance levels.

_Developers fine-tuning SwiftUI toolbar layouts can find implementation details like this one on daily.dev._

### How do I pin a SwiftUI toolbar item to always stay at the trailing edge?

Use the topBarPinnedTrailing placement on a ToolbarItem, which keeps the item at the trailing edge as the toolbar narrows while other items move into overflow around it. It is a stronger commitment than a high visibilityPriority and should be reserved for actions that truly need a fixed, visible position. Pinned items can still move into overflow when search is active and space is tight.

_Track SwiftUI API changes like this one on daily.dev when deciding how to structure adaptive toolbars._

### What replaced the statusBarHidden(_:) modifier in iOS 27 SwiftUI?

ToolbarPlacement.statusBar now represents the status bar, so its visibility is controlled through the same toolbarVisibility(_:for:) API used for other bars, for example toolbarVisibility(.hidden, for: .statusBar). This replaces the older statusBarHidden(_:) modifier starting in iOS 27, unifying status bar control with the rest of the toolbar placement system.

_Developers migrating SwiftUI code off deprecated modifiers can catch changes like this via daily.dev._
