I am having difficulty in converting an Int32 to String. I tried to following:
String(cartItem?.quantity)
"\\(cartItem?.quantity)"
but no luck.
cart.quantity
is of type Int32.
quantity is an attribute of cart in the CoreData model.
The question isn't clear but what I think this issue boils down to is that you can't init a string with an optional value.
So either do as @matt suggested and force unwrap the cartItem
String(cartItem!.quantity)
or supply a default value
String(cartItem?.quantity ?? 0)
Of course if you need to handle the fact that you might not have a cart then it is better to do it like
if let cart = cartItem {
let str = "\(cart.quantity)" //or String(cart.quantity)
//do stuff with str
} else {
//handle no cart state
}
you can by declare string and data
var arrayOf32Int: [UInt32] = [1,32,100,984,13,542]
let data = Data(bytes: arrayOf32Int, count: arrayOf32Int.count * MemoryLayout<UInt32>.stride)
let string = String(data: data, encoding: .utf32LittleEndian)!
print(string)
