I am a beginner level programmer in iOS app development using Swift. Now I am facing the compile time issue "UInt8 is not convertible to CGFloat"
var numberOfAvatars:Int = 8
let count:Int = 1
let columns:Int = 3
let dimension:CGFloat = 84.0
var spacing:CGFloat = (avatarContentcroll.frame.size.width - columns * dimension)/(columns+1)
var scHeight:CGFloat = spacing + (numberOfAvatars/columns) * (dimension + spacing)
I've tried all the solutions out there and did many experiments. And I am not sure why still I am getting this error.
You have to do it explicitly as
var spacing:CGFloat = CGFloat((avatarContentcroll.frame.size.width) - CGFloat(columns) * (dimension))/(columns+1)
var scHeight:CGFloat = CGFloat(spacing + (CGFloat(numberOfAvatars)/CGFloat(columns)) * (dimension + spacing))
or you can try converting every expression in CGFloat
var spacing:CGFloat = ((avatarContentcroll.frame.size.width) - CGFloat(columns) * (dimension))/(columns+1)
var scHeight:CGFloat = spacing + (CGFloat(numberOfAvatars)/CGFloat(columns)) * (dimension + spacing)
You must explicitly cast your Int
s as CGFloat
s (via as
), or construct them -- like so:
var spacing:CGFloat = ((avatarContentcroll.frame.size.width) - CGFloat(columns) * (dimension))/(columns+1)
var scHeight:CGFloat = spacing + (CGFloat(numberOfAvatars)/CGFloat(columns)) * (dimension + spacing)
