Use of variables

[vandilsonlima]

why can't I do this? let w = 100 view.widthAnchor == w Compile says

Binary operator '==' cannot be applied to operants of type NSLayoutDimension' and 'Int'

while this is possible view.widthAnchor == 100

@vandilsonlima the compiler is inferring that w is an int, to use a variable in a layout expression, the value needs to be a CGFloat

let w: CGFloat = 100
view.widthAnchor == w

Should compile

@ateliercw thanks for your help. I didn't notice that I should use a CGFloat instead of an Int.
