3.0.0

[3.0.0] - 2026-08-20

Fluidable now builds in the Swift 6 language mode. Adopting this release
requires source changes in any project that conforms to Fluidable's delegate
protocols or matches on FluidCoreAnimatorError.

Minimum requirements are unchanged: iOS 15.0 or later, built with Xcode 26.

Breaking Changes

1. Delegate protocols and view-facing types are now @MainActor

FluidDelegate is annotated with @MainActor, so every protocol that inherits
from it is main-actor isolated as well:

• FluidTransitionConfigurationDelegate
• FluidTransitionActionDelegate
• FluidTransitionSourceConfigurationDelegate
• FluidTransitionDestinationConfigurationDelegate
• FluidTransitionSourceActionDelegate
• FluidTransitionDestinationActionDelegate
• FluidNavigationConfigurationDelegate
• FluidNavigationActionDelegate
• FluidNavigationSourceConfigurationDelegate
• FluidNavigationDestinationConfigurationDelegate
• FluidNavigationSourceActionDelegate
• FluidNavigationDestinationActionDelegate

The following declarations are annotated directly:

• FluidResizableTransitionDelegate
• FluidNavigationBarCompatible
• FluidFrameDimensionCompatible
• FluidInteractiveView
• FluidBackgroundCompatible
• FluidAnimatorCompatible
• FluidCoreAnimatorLayerConvertible
• AdaptiveElement
• AdaptiveInterface
• FluidNavigationControllerDelegate
• FluidViewControllerTransitioningDelegate
• FluidLayout

Conforming types must be main-actor isolated. UIViewController and UIView
subclasses already are, so most conformances keep compiling unchanged. A
conformance declared on a type that is not isolated needs an explicit
annotation:

// Before (2.x)
final class TransitionCoordinator: NSObject, FluidTransitionSourceConfigurationDelegate {
    func transitionPresentationStyle(from source: FluidSourceViewController,
                                     to destination: FluidDestinationViewController,
                                     with navigation: FluidNavigationController?) -> FluidTransitionStyle {
        return .fluid(behavior: .all)
    }
}

// After (3.0.0)
@MainActor
final class TransitionCoordinator: NSObject, FluidTransitionSourceConfigurationDelegate {
    func transitionPresentationStyle(from source: FluidSourceViewController,
                                     to destination: FluidDestinationViewController,
                                     with navigation: FluidNavigationController?) -> FluidTransitionStyle {
        return .fluid(behavior: .all)
    }
}

Any access to these types from a non-isolated context now has to hop to the
main actor, for example with await MainActor.run { ... } or by marking the
calling function @MainActor.

2. FluidCoreAnimatorError.invalidArgument carries String instead of Any?

The from and to payloads changed from Any? to String so that the error
is Sendable. The values are formatted with String(describing:) before the
error is thrown, so the rendered text is unchanged.

// Before (2.x)
case .invalidArgument(let id, let key, let from, let to):
    print(id, key, String(describing: from), String(describing: to))

// After (3.0.0)
case .invalidArgument(let id, let key, let from, let to):
    print(id, key, from, to)

3. FluidRoundCornerStyle.all raw value changed from 11 to 15

all was defined as [.top, .right, .left, .left], which omitted .bottom
and duplicated .left. As a result all.contains(.bottom) returned false
and its description dropped bottom. It is now [.top, .right, .bottom, .left].

// Before (2.x)
FluidRoundCornerStyle.all.rawValue          // 11
FluidRoundCornerStyle.all.contains(.bottom) // false

// After (3.0.0)
FluidRoundCornerStyle.all.rawValue          // 15
FluidRoundCornerStyle.all.contains(.bottom) // true

If you persisted the raw value of all, remap 11 to 15 when reading it
back:

let stored: Int = defaults.integer(forKey: "cornerStyle")
let style: FluidRoundCornerStyle = stored == 11 ? .all : .init(rawValue: stored)

4. roundingCorners and maskedCorners now honour arbitrary combinations

Both accessors matched self against the five named constants with a switch.
Because switch on an OptionSet is exact equality, any other combination fell
through to default and produced no rounding. They now union the corner sets of
every flag they contain, so combinations that were silently ignored start taking
effect.

let style: FluidRoundCornerStyle = [.top, .right]

// Before (2.x)
style.roundingCorners  // nil
style.maskedCorners    // []

// After (3.0.0)
style.roundingCorners  // [.topLeft, .topRight, .bottomRight]
style.maskedCorners    // [.layerMinXMinYCorner, .layerMaxXMinYCorner, .layerMaxXMaxYCorner]

roundingCorners still returns UIRectCorner.allCorners when all four corners
are selected, because allCorners has a raw value of ~0 and is not equal to
the union of the four individual corners.

Added

• Sendable conformance for the public value types: FluidDriverType,
  FluidAnimationType, FluidBackgroundStyle, FluidDriverInteractionType,
  FluidNavigationStyle, FluidPresentationStyle, FluidSlideDirection,
  FluidDrawerPosition, FluidTransitionStyle, FluidGestureDirection,
  PennerEasing, FluidAnimatorEasing, FluidAnimatorState,
  FluidInteractionBehavior, FluidRoundCornerStyle, and FluidGestureAxis.
• PrivacyInfo.xcprivacy privacy manifest, shipped with both the SwiftPM
  resource bundle and the Xcode framework target. Fluidable collects no data
  and uses no required-reason API, so every key is declared empty.

Changed

• The library, the test target, the example app, and the UI test target all
  build in the Swift 6 language mode.

Fixed

• FluidRoundCornerStyle.all now includes .bottom. See breaking change 3.
• roundingCorners and maskedCorners now round the corners of any flag
  combination instead of only the five named constants. See breaking change 4.
