This is also an issue on SYNC Gen 1.1 and is a problem for app partners who want to upgrade to the newest SDK but also support as many vehicles as possible.
It may be better to just remove the check for the display capabilities since the RPC response will also indicate if it is supported or not.

Proposed solution:

- (nullable SDLCreateInteractionChoiceSet *)sdl_choiceFromCell:(SDLChoiceCell *)cell {
    NSArray<NSString *> *vrCommands = nil;
    if (cell.voiceCommands == nil) {
        vrCommands = self.isVROptional ? nil : @[[NSString stringWithFormat:@"%hu", cell.choiceId]];
    } else {
        vrCommands = cell.voiceCommands;
    }
    
    if(![self.displayCapabilities hasTextFieldOfName:SDLTextFieldNameMenuName]) {
        SDLLogW(@"This display may not support SDLCreateInteractionChoiceSet. It may not be shown. Cell: %@", cell);
    }
    NSString *menuName = cell.text;
    NSString *secondaryText = cell.secondaryText;
    NSString *tertiaryText = cell.tertiaryText;
    SDLImage *image = cell.artwork != nil ? cell.artwork.imageRPC : nil;
    SDLImage *secondaryImage = cell.secondaryArtwork != nil ? cell.secondaryArtwork.imageRPC : nil;

    SDLChoice *choice = [[SDLChoice alloc] initWithId:cell.choiceId menuName:menuName vrCommands:(NSArray<NSString *> * _Nonnull)vrCommands image:image secondaryText:secondaryText secondaryImage:secondaryImage tertiaryText:tertiaryText];
    return [[SDLCreateInteractionChoiceSet alloc] initWithId:(UInt32)choice.choiceID.unsignedIntValue choiceSet:@[choice]];
}
