Add explicit UIKit/AppKit imports for Library Evolution support

[shreks7]

To allow YouTubePlayerKit to be used part of the xcframework and when
BUILD_LIBRARY_FOR_DISTRIBUTION=YES is set.

Great find 👍

Have you tried to just use import SwiftUI as it already handles the conditional import of UIKit and AppKit?
Similarly to the conditional declaration of the Image typealias of the YouTubeVideoThumbnail which only imports SwiftUI.

YouTubePlayerKit/Sources/VideoThumbnail/YouTubeVideoThumbnail.swift

Line 2 in c2665ad

import SwiftUI

YouTubePlayerKit/Sources/VideoThumbnail/YouTubeVideoThumbnail.swift

Lines 131 to 137 in c2665ad

	#if os(macOS)
	/// A video thumbnail image.
	typealias Image = NSImage
	#else
	/// A video thumbnail image.
	typealias Image = UIImage
	#endif

Ah that is simpler and easier! It works.
