Copy code
class Human(val name: String, age: Int) {
    var age = age
        private set
    
    fun birthday() {
        //party hard
        age++
    }
}
can this be simplified somehow or is it good as is?

If immutable class will work in your case, then you can write:
Copy code
data class Human(
    val name: String,
    val age: Int
)

fun Human.birthday() = copy(age = age + 1)
In this case 
birthday
returns new instance instead of modifying existing one.

nah it needs to be mutable, i was wondering if its possible to set getters and setters for variables declared in the primary constructor (like 
name
in my example)

Copy code
data class Human(
    val name: String,
    private var age: Int
) {
    fun birthday() {
        //party hard
        age++
    }
}

@dawidhyzy in your example the setter of 
age
isn't private, is it?

then I think this is the best you can get:
Copy code
class Human(val name: String, age: Int) {
    var age = age
        private set
    
    fun birthday() {
        //party hard
        age++
    }
}
