Since this is a framework header, it should import other WebCore headers using <WebCore/ syntax.

Missing space before the <.

This could probably be nonatomic (as could may other properties here).

Can be nonatomic.

> +@property (nonatomic, retain, readwrite) NSArray<AVFunctionBarMediaSelectionOption *> *audioFunctionBarMediaSelectionOptions;
> +@property (nonatomic, retain, readwrite) NSArray<AVFunctionBarMediaSelectionOption *> *legibleFunctionBarMediaSelectionOptions;

We normally omit “readwrite” when possible. It’s a little unusual for a property whose value is NSArray to be “retain” rather than “copy”.

> Source/WebCore/platform/mac/WebPlaybackControlsManager.mm:98

Missing space between the brackets.

> Source/WebCore/platform/mac/WebPlaybackControlsManager.mm:104
> +    completionHandler(@[], nil);

Ditto.

> +    _audioFunctionBarMediaSelectionOptions = audioOptions;

I’d make a copy of audioOptions here (and change the property from “retain” to “copy”.

We normally don’t use trivial accessors from within a class’s own implementation, but just use the ivar directly.

> +    _legibleFunctionBarMediaSelectionOptions = legibleOptions;

I’d make a copy of legibleOptions here (and change the property from “retain” to “copy”.

Added nonatomic.

We discussed this on irc and agreed that this can be removed from the header because it's a part of the protocol.
