Imagine if all the wallets on Earth of every coin on Earth had one more button in them - an "Escrow" button, which would be as natural to any wallet as the "Send" button now.
If blockchain can safely swap values between addresses in a trustless system, why don't we use the same mechanism to safely escrow the values in a trustless system to safely meet the conditions of the swap? And one won't need any additional app to swap values - any values. I'm talking about all-swap thing.
