Swift 2.0 : Confused between update frames vs constraints

Pasan Premaratne and others

I'm a little confused between update frames vs constraints. I usually try one or the other until I get what I want. Instead of that approach I want to understand what both are and how to pick it.

Thanks in advance

Welby,

Here's now I understand it.

If you update Frames, your object on the screen gets modified. Meaning, if you have a label, the computer looks at the constraints you set up, and it moves and or changes the size of the label in accordance to what constraints are set up.

If you update constraints, the computer looks at the location and size of the your object, and changes the constraints.
