I rule they just have to be in your spell component pouch - you grab your sack quick and cast, then go back to having both hands on your weapon.
All this innuendo is making Eric's grandma blush.

I used to be in the "you can hold it with one hand" crowd, but I changed my stance soon after. Those that wield with two hands (without War Caster) must sheathe or drop before casting. It makes the versatile property useful for fighter-mage types.
The thing where you don't use your object interaction to drop something is totally a house rule. It's really commonly used, but beware of building a rules argument that includes it.
http://www.sageadvice.eu/tag/interaction/Pretty sure that it qualifies as DM purview under not an action, like talking or other trivial things. So, you could totally build a rules argument on that foundation. Also, I think Crawford weighed in that it's not an action via twitter at some point, so that's even more sturdiness to the foundation.![]()
It's a lot easier to hold a "2 handed" weapon in one hand than it is to try and hold two regular weapons in the same hand or a sword in a hand that's supposed to be holding a shield strap...
Saying you can't hold a great sword in one hand while waving the other around is like saying it's impossible to turn the handle on a door if your great sword is is unsheathed. It's unrealistic, untypical and just wrong on a lot of levels.
Dual wielding makes more sense to require a weapon to be dropped or stowed due to the awkwardness of trying to hold two item in one hand or under your arm, etc...
