Safe Areas 安全区
A safe area defines the area within a view that isn’t covered by a navigation bar, tab bar, toolbar, or other views a window or scene might provide. Safe areas are essential for avoiding a device’s interactive and display features, like the Dynamic Island on iPhone or the camera housing on some Mac models.
译: 安全区域定义视图中未被导航栏、选项卡栏、工具栏或窗口或场景可能提供的其他视图覆盖的区域。 安全区域对于避免设备的交互和显示功能至关重要，例如 iPhone 上的动态岛或某些 Mac 机型上的摄像头外壳。

Status Bar 状态栏
Tips: 从ios14开始有刘海屏的iPhone状态栏高度不一定是44了, 故之前判定是全面屏的相关宏将不再适用 !
// 不再适用
