Aug 01, 2019 If you know apple unveiled dark mode finally on MacOS officially but by default come to turn off dark mode macOS Catalina. So you can enable or turn on dark mode from the Mac settings. Dark mode on macOS help to get documents, Xcode for Developers. Oct 12, 2018 The Dark Mode theme available in MacOS Mojave 10.14 onward offers a unique visual interface and desktop environment to work in, shifting nearly all onscreen visual elements to dark grays and blacks. For many Mac users, the Dark theme is perhaps the most popular new feature to arrive in MacOS Mojave.
In iOS 13, Apple has included a system-wide Dark Mode option similar to the one it brought to the Mac in 2018 with the release of macOS Mojave. Dark Mode is designed to be easier on the eyes by providing less harsh display brightness in situations where ambient lighting is lower, while maintaining contrast and vibrancy.
If you have an OLED iPhone, such as an iPhone X, iPhone XS, or iPhone XS Max, enabling Dark Mode may also conserve battery life whenever true blacks are on screen, since black pixels in an OLED panel basically switch off and consume far less power.
Enabling Dark Mode in iOS 13 is easy – simply follow the steps below.
- Launch the Settings app on your iPhone or iPad.
- Tap Display & Brightness.
- Under Appearance, tap Dark to switch to Dark Mode.
Alternately, you can set a custom schedule for the display change by using the Options menu that appears when you toggle on the Automatic switch.

Update colors, images, and behaviors so that your app adapts automatically when Dark Mode is active.
Overview
In macOS and iOS, users can choose to adopt a system-wide light or dark appearance. The dark appearance, known as Dark Mode, implements an interface style that many apps already adopt. Users choose the aesthetic they prefer, and can also choose to toggle their interface based on ambient lighting conditions or a specific schedule.
All apps should support both light and dark interface styles, but might perform better with a specific appearance in some places. For example, you might always adopt a light appearance for printed content.
Before you change your code, turn on Dark Mode and see how your app responds. The system does a lot of the work for you, and if your app uses standard views and controls, you might not need to make many changes. Standard views and controls automatically update their appearance to match the current interface style. If you already use color and image assets, you can add dark variants without changing your code.
Choose Adaptive Colors for Your UI
Choose colors that adapt automatically to the underlying interface style. Light and dark interfaces use very different color palettes. Colors that work well in a light appearance may be hard to see in a dark appearance, and vice versa. An adaptive color object returns different color values for different interface styles.
There are two ways to create adaptive color objects:
- Choose semantic colors instead of fixed color values. When configuring UI elements, choose colors with names like
labelColor
. These semantic colors convey the intended use of the color, rather than specific color values. When you use them for their intended purpose, they render with color values appropriate for the current settings. For a complete list of semantic color names, seeNSColor
andUIColor
. - Define custom colors in your asset catalog. When you need a specific color, create it as a color asset. In your asset, specify different color values for both light and dark appearances. You can also specify high-contrast versions of your colors.
You configure custom color assets using Xcode’s asset editor. Add a Color Set asset to your project and configure the appearance variants you want to modify. Use the Any Appearance variant to specify the color value to use on older systems that do not support Dark Mode. Password safe for mac.
To load a color value from an asset catalog, load the color by name:
When you create a color object from a color asset, you do not have to recreate that object when the current appearance changes. Each time you set the fill or stroke color for drawing, the color object loads the color variant that matches the current environment settings. The same is true for semantic colors such as
labelColor
, which adapt automatically to the current environment. By contrast, color objects you create using fixed component values do not adapt; you must create a new color object instead. Note
For the user's content, always preserve colors that the user explicitly chooses. For example, a painting app should not try to change colors that the user applies to their canvas. Use adaptable colors primarily in the views and controls for your app’s chrome.
Create Images for All Appearances
Make sure the images in your interface look good in both light and dark appearances. Interfaces use images in many places, including in buttons, image views, and custom views and controls. If an image is difficult to see when changing appearances, provide a new image asset that looks good in the other appearance. Better yet, use a symbol image or template image, which define only the shape to render and therefore do not require separate images for light, dark, and high-contrast environments. https://hidhifz.weebly.com/miracast-for-mac.html.
For information about configuring images for both light and dark interfaces, see Providing Images for Different Appearances.
Update Custom Views Using Specific Methods
When the user changes the system appearance, the system automatically asks each window and view to redraw itself. During this process, the system calls several well-known methods for both macOS and iOS, listed in the following table, to update your content. The system updates the trait environment before calling these methods, so if you make all of your appearance-sensitive changes in them, your app updates itself correctly.
If you make appearance-sensitive changes outside of these methods, your app may not draw its content correctly for the current environment. The solution is to move your code into these methods. For example, instead of setting the background color of an
NSView
object's layer at creation time, move that code to your view’s updateLayer()
method instead, as shown in the code example below. Setting the background color at creation time might seem appropriate, but because CGColor
objects do not adapt, setting it at creation time leaves the view with a fixed background color that never changes. Moving your code to updateLayer()
refreshes that background color whenever the environment changes. Choose Visual-Effect Materials Based on the Intended Usage
Visual-effect views add transparency to your background views, which gives your UI more visual depth than if the backgrounds were opaque. To ensure that your content remains visible, visual-effect views blur the background content subtly and add vibrancy effects to adjust the colors of your foreground content automatically. The system updates these effects dynamically, ensuring that your app's content remains visible when the underlying content changes.
Use visual-effect views in your interface as container views, and add subviews to them to represent your foreground content. Configure each visual-effect view with the material or effects that are appropriate for the appearance you want:
Mac Os X Dark Mode
- In macOS, configure an
NSVisualEffectView
with the appropriate material based on how you use that view in your interface. For example, when using a visual-effect view as the background for a sidebar interface, configure it with theNSVisualEffectView.Material.sidebar
material. - In iOS, configure a
UIVisualEffectView
with specific vibrancy and blur effects to create the appearance you want. Blur effects define the apparent thickness of the background view, and vibrancy effects adjust the appearance for specific types of content to ensure that they remain visible. For example, when your view contains labels, choose theUIVibrancyEffectStyle.label
style or one of the other label-related vibrancy options.
Important
Do not use deprecated materials, such as
NSVisualEffectView.Material.light
, in macOS 10.14 and later because those materials do not adapt to Dark Mode. Instead, choose newer materials that adapt correctly to the environment. Opt Out Only as Needed
Make every effort to adopt both light and dark appearances in your apps. If supporting one appearance makes no sense for all or part of your app, you can opt out of appearance changes in the appropriate windows or views. For example, you might always use a light appearance for your app's printing views.
You can configure all or part of your interface to opt out of a specific appearance. You can also adopt a specific appearance for your entire app. For more information, see the following:
Avoid Expensive Tasks During Appearance Transitions
When the user toggles between light and dark interfaces, the system asks your app to redraw all of its content. Although the system manages the drawing process, it relies on your custom code at several points during that process. Your code must be as quick as possible and not perform tasks unrelated to the appearance change. In macOS, AppKit usually creates transition animations during appearance changes, but it aborts those animations if your app takes too long to redraw itself.
