Consider the following code:
let op1: Int = 1
let op2: UInt = 2
let op3: Double = 3.34
var result = op1 + op2 + op3
Where is the error and why? How can it be fixed?

Swift doesn’t define any implicit cast between data types, even if they are conceptually almost identical (like UInt and Int).
To fix the error, rather than casting, an explicit conversion is required. In the sample code, all expression operands must be converted to a common same type, which in this case is Double:
var result = Double(op1) + Double(op2) + op3
