For in loop inside or outside UIView.animate block?

Does one of the following functions has an advanced over the other, or does it not matter in performance/best practice?

1.
UIView.animate(withDuration: 1){
    for b in self.someArray{
        b.frame.origin = self.myNewPosition
    }
}

2.
for b in self.someArray{
    UIView.animate(withDuration: 1){
        b.frame.origin = self.myNewPosition
    }
}

Option 1 creates a single animation and all of the updated properties are animated together.

Option 2 creates X number of animations and each one can do whatever you want.

Use option 1 if you want all of the origins to change at the same time for the same duration.

Use option 2 if you want a different animation for each object in the array.
