Why you should care
For code readability purpose, if a property initializer is a scalar value or the return type can be clearly inferred from the body then it can be omitted.
How we detect
CAST Highlight counts one occurrence each time a variable (or class property) is declared with an explicit type and initialized with one of the following scalar values:
- “…” or ‘…’ (string)
- false or true (boolean)
- integer or signed integer
- decimal : a dot followed by a digit number
var a : String = "it's a string" // +1 VIOLATION val b : Boolean = false // +1 VIOLATION const val c : Int = 123 // +1 VIOLATION val d : Any = -123 // +1 VIOLATION val e : Float = .123 // +1 VIOLATION
