I have read this (Difference between computed property and property set with closure) helpful question but it doesn't fully answer something i'd like to know.

It answers the difference between: 

//closure
var pushBehavior: UIPushBehavior = {
    let lazilyCreatedPush = UIPushBehavior()
    lazilyCreatedPush.setAngle(50, magnitude: 50)
    return lazilyCreatedPush
}()

and

//computed
var pushBehavior: UIPushBehavior {
    get{
        let lazilyCreatedPush = UIPushBehavior()
        lazilyCreatedPush.setAngle(50, magnitude: 50)
        return lazilyCreatedPush
    }
}

I understand this. Now if we change the first one what is the difference between the computed variable in the second example and this: 

var pushBehavior: UIPushBehavior {
    let lazilyCreatedPush = UIPushBehavior()
    lazilyCreatedPush.setAngle(50, magnitude: 50)
    return lazilyCreatedPush
}

To me this acts exactly like the get{} but without the get keyword. Is that the case and if so why do we have the get keyword?

There is no difference.

From the documentation

You can simplify the declaration of a read-only computed property by removing the get keyword and its braces.
