Description

XCode complains:
Pattern that the region based isolation checker does not understand how to check. Please file a bug.

Reproduction

 import SwiftUI
 import UIKit

 public actor TextLayoutManager: NSObject, NSTextContentStorageDelegate, NSTextLayoutManagerDelegate
 {
     private let textContentStorage: NSTextContentStorage
     private let textLayoutManager: NSTextLayoutManager
     public let textContainer: NSTextContainer
     private(set) var lineRects: [CGRect] = []

     public override init() {
         textLayoutManager = NSTextLayoutManager()
         textContentStorage = NSTextContentStorage()
         textContainer = NSTextContainer(size: CGSize(width: 0, height: 0))
         super.init()
         textContainer.lineFragmentPadding = 0
         textContainer.lineBreakMode = .byWordWrapping
         textContainer.maximumNumberOfLines = 0
         textLayoutManager.textContainer = textContainer
         textLayoutManager.delegate = self
         textContentStorage.delegate = self
         textContentStorage.textStorage = NSTextStorage()
         textContentStorage.addTextLayoutManager(textLayoutManager)
     }
 }

It should compiles.
