Existing backing field without assignment

Last modified: 03 December 2024

Reports property setters that don't update the backing field.

The quick-fix adds an assignment to the backing field.

Example:

class Test {
    var foo: Int = 1
        set(value) {
        }
}

After the quick-fix is applied:

class Test {
    var foo: Int = 1
        set(value) {
            field = value
        }
}
