Ever since I've updated to Xcode 15.2 (I'm currently using Xcode 15.3) my console gets flooded with logs from CFNetwork and DataDetectorsUI. I've never seen those logs before. Is there a way to suppress them? I can't even find my own logs anymore without filters.

It seems like a WKWebView doesn't handle 421 responses automatically.
What basically happened is the following:
The client requests a page at foo.example.com
During TLS negotiation, the server presents a certificate which is valid for both foo.example.com and bar.example.com (and the client accepts it). This could be done with a wildcard certificate or a SAN certificate.
The client reuses the connection to make a request for bar.example.com.
The server is unable or unwilling to support cross-domain connection reuse and serves HTTP 421.
The client does not automatically retry with a new connection.
According to the RFC7540 section 9.1.2 we MAY retry the request manually with a new TCP connection.
The iOS' Safari browser and all web browsers handled this correctly by retrying the request.
Isn't the webview also supposed to handle this automatically? @eskimo

If I put the code for my UIBezierPath inside the draw(_ rect:) function I get these strange very thin black corners around the view and the tail. When dragging the view (e.g. within a presented view controller) these thin lines also start flickering. I assume it's a weird rendering bug. Does anyone know if there is a way to fix this?
To test this, just put the following view inside a view controller
class RenderingView: UIView {
		lazy var backgroundView: UIView = {
				let view = UIView()
				view.layer.cornerRadius = 8
				view.translatesAutoresizingMaskIntoConstraints = false
				return view
		}()
		private lazy var shadowView: UIView = {
				let view = UIView()
				view.translatesAutoresizingMaskIntoConstraints = false
				return view
		}()
		private lazy var textLabel: UILabel = {
				let label = UILabel()
				label.numberOfLines = 0
				label.textAlignment = .center
				label.translatesAutoresizingMaskIntoConstraints = false
				label.text = "Rendering Bug"
				return label
		}()
		override init(frame: CGRect) {
				super.init(frame: frame)
				setup()
		}
		required init?(coder: NSCoder) {
				fatalError("init(coder:) has not been implemented")
		}
		private func setup() {
				backgroundColor = .clear
				backgroundView.backgroundColor = .yellow
				layer.borderWidth = 0
				setupLayout()
		}
		private func setupLayout() {
				[shadowView, backgroundView, textLabel].forEach(addSubview)
				backgroundView.leadingAnchor.constraint(equalTo: leadingAnchor).isActive = true
				backgroundView.topAnchor.constraint(equalTo: topAnchor).isActive = true
				backgroundView.trailingAnchor.constraint(equalTo: trailingAnchor).isActive = true
				backgroundView.bottomAnchor.constraint(equalTo: bottomAnchor).isActive = true
				shadowView.leadingAnchor.constraint(equalTo: backgroundView.leadingAnchor).isActive = true
				shadowView.topAnchor.constraint(equalTo: backgroundView.topAnchor).isActive = true
				shadowView.trailingAnchor.constraint(equalTo: backgroundView.trailingAnchor).isActive = true
				shadowView.bottomAnchor.constraint(equalTo: backgroundView.bottomAnchor).isActive = true
				textLabel.leadingAnchor.constraint(equalTo: backgroundView.leadingAnchor, constant: 10).isActive = true
				textLabel.trailingAnchor.constraint(equalTo: backgroundView.trailingAnchor, constant: -10).isActive = true
				textLabel.topAnchor.constraint(equalTo: backgroundView.topAnchor, constant: 10).isActive = true
				textLabel.bottomAnchor.constraint(equalTo: backgroundView.bottomAnchor, constant: -10).isActive = true
		}
		override func draw(_ rect: CGRect) {
				shapeBackground()
		}
		private func shapeBackground() {
				let tailLayer = CAShapeLayer()
				let bezierPath = UIBezierPath(roundedRect: CGRect(x: backgroundView.bounds.minX,
																													y: backgroundView.bounds.minY,
																													width: backgroundView.bounds.width,
																													height: backgroundView.bounds.height - 12),
																			cornerRadius: 8)
				let shadowBezierPath = UIBezierPath(roundedRect: CGRect(x: backgroundView.bounds.minX + 5,
																																y: backgroundView.bounds.minY + 10,
																																width: backgroundView.bounds.width - 10,
																																height: backgroundView.bounds.height - 12 - 10),
																						cornerRadius: 8)
				[bezierPath, shadowBezierPath].forEach {
						$0.move(to: CGPoint(x: backgroundView.bounds.midX - 12, y: backgroundView.bounds.maxY - 12))
						$0.addLine(to: CGPoint(x: backgroundView.bounds.midX, y: backgroundView.bounds.maxY))
						$0.addLine(to: CGPoint(x: backgroundView.bounds.midX + 12, y: backgroundView.bounds.maxY - 12))
						$0.fill()
						$0.close()
				}
				tailLayer.path = bezierPath.cgPath
				tailLayer.fillColor = UIColor.white.cgColor
				shadowView.layer.shadowPath = shadowBezierPath.cgPath
				shadowView.layer.cornerRadius = 8
				backgroundView.layer.masksToBounds = true
				backgroundView.layer.mask = tailLayer
		}
