watchOS 是否有替代图标？
Is alternative icon available for watchOS?
从iOS 10.3开始，开发者可以设置alternative icons，这很好。
配套的 watchOS 应用是否支持它？
我的应用最近因此被拒绝了。
Specifically, we noticed that for the user selected alternative icon themes no alternative Apple Watch icons matching the iPhone icon theme were submitted.
来自 Apple 的 Human Interface Guidelines，您应该为备用图标提供各种尺寸。
对于您的情况，您应该提供 watchOS 应用程序大小的图标。
Like your primary app icon, each alternate app icon is delivered as a collection of related images that vary in size. When the user chooses an alternate icon, the appropriate sizes of that icon replace your primary app icon on the Home screen, in Spotlight, and elsewhere in the system. To ensure that alternate icons appear consistently throughout the system—the user shouldn't see one version of your icon on the Home screen and a completely different version in Settings, for example—provide them in the same sizes you provide for your primary app icon (with the exception of the large App Store icon). See App Icon Sizes.
如何：
info.plist中CFBundleIconFiles的值是一个数组。你应该用图标文件的名称填充它：
- 无@2x @3x后缀
- 没有关于文件命名的强制规则，应用程序会根据需要自动选择正确的解决方案。
- 不关心顺序
从 watchOS 4.0 beta 开始，watchOS 不支持备用图标。
我最终回答了 Apple Review 团队，该应用旨在不在 Watch App 中提供备用图标。
