how to get count of array outside tableview method swift

Question

I want to increase UIView size according to array count. Currently, I am doing this -:

var socialMediaURLSArray = [URL]()

and in View did load i am doing this -:

 viewHeightConstraints.constant = (60 * 1) + 170

In place of 1, I want to define socialMediaURLSArray count.

In place of 1, I want to define socialMediaURLSArray count.

so

viewHeightConstraints.constant = (60 * socialMediaURLSArray.count) + 170

You may need to to the above code inside the didSet of the socialMediaURLSArray to make it auto update.

_{You may need to call view.layoutIfNeeded() to update the constraint. Also you can perform it inside an animation block}

it always show socialMediaURLSArray.count = 0

Are you appending urls to the socialMediaURLSArray ?
