Current functionality returns an Any from the value
property for an element, which means that the developer user has to downcast to the specific type required when getting the value, for example:
let myValue = element.value as! Float
Also, while setting the value does not require type casting (because the value is being set to Any, any typed value will do), setting the wrong typed value will lead to a run-time error.
By creating type-specific versions of the value
property, such as floatValue
, type safety will be enforced at compile time for both getting and setting, and make code more readable:
let myValue = element.floatValue
It wold be possible to do automatic casting for the decimal types. For example, if the element data type is Int and the underlying value is an Int, the user could nevertheless obtain the value using floatValue
and the value would be automatically cast to the desired type. However, such an approach could lead to unintended consequences and errors, and undermines the compile time type safety this change offers.
