Setting Up App Icons in Xcode 26 with Icon Composer

幸好在 Xcode 中设置 Icon 和 Launch Screen 比较简单，不用花多少功夫，现在就让我们 diving in吧。 首先，要准备4组图标（如果是发布在 iOS 平台上），这4组分别是 120 x 120 px， 152 x 152 px， 167 x 167 px， 1024 x 1024 px 的尺寸，要 PNG 格式。 然后，将这4张图片 Add Files to <Your Project>。 最后，在你的 xcodeproj 中将 App Icons Source 设

Use Icon Composer to create a single multilayer file that you can add to your Xcode project to represent your Liquid Glass app icon everywhere your app icon appears across iOS, iPadOS, macOS, watchOS, and the App Store.

问题原因 当我下载App Store中的应用，Image仍然可以获取到iOS App Icon。 当我从Git Hub中下载App Store版本，并安装到手机上时，仍然是无法获取iOS App Icon的。 因此，我认为问题可能是 Xcode 16 对资源加载机制的更改 以及 App Icon 不再作为普通资源提供访问 有关。

Here's a friendly breakdown, including common pitfalls and alternative methods. The core idea is to use the new .icon file format created by Icon Composer as your single source of truth.

If you use Xcode 26 to build your app, then when the app is run on a device or simulator with iOS 26, then the Icon Composer file (glass app icon) is used. But if the app is run on a device or simulator with iOS 18 or earlier, it will use the existing App

Using Icon Composer, you add the background, adjust size and positions of the layers, set opacity, color/gradients, shadows, and glass effects. Xcode uses the single .icon file to generate all the icon variants it needs for all supported platforms.

今天在添加app icon的时候发现，现在在XCode上一张图片就够了。
