this example uses Dynamic Font with respect to line height line height

DynamicFontLineHeight.swift

// MARK: - Helper

struct Layout { // this uses Dynamic Font and calculates spacing for correct line height
  static let weight = SwiftUI.Font.Weight.semibold
  static let size = UIFontMetrics.default.scaledValue(for: 17)
  static let lineHeight = UIFontMetrics.default.scaledValue(for: 22)
  static let uiFont = UIFont.systemFont(ofSize: size, weight: weight.toUIKit())
  static let spacing = max(0, lineHeight - uiFont.lineHeight)
}

// MARK: - Usage

struct ContentView: View {
  var body: some View {
    Text("Hello nerd")
      .font(.system(size: Layout.size, weight: Layout.weight))
      .lineSpacing(Layout.lineHeight)
      .padding(.vertical, Layout.spacing/2)
  }
