Apple needs to understand that it will take much more than just solely depending on Indie games. Otherwise it is going to show the world they are very inexperienced in gaming. Not saying I am against mobile games, as I am a fan of Monument Valley. But they need to treat the Apple Arcade service like the iBooks store. Offering a wide range and similar titles that is already available in other places.
As mentioned in the other post, if Nintendo really join forces with Apple, it would certainly make a historical moment in gaming. A way to make this possibly work would involve something that has never been done before. For example, if the Switch retail price is $299. Nintendo could charge the same cost by building a Switch emulator baked into iOS. Where the user pays the same price to unlock it. And instantly the entire library on Nintendo’s eShop will be accessible to millions of people without impacting hardware sales. Also Nintendo can make more money if they build Joy-Con controllers specifically designed for iPhones. For the iPad, that can easily be solved by having their Switch Pro Controller paired with it.
