I have an array defined using RxSwift as
public var calendarNDays = BehaviorRelay<[CalendarControlDayModel]>(value: [])
CalendarControlDayModel is a structure as below.
struct CalendarControlDayModel {
var date: String = ""
var day: Int = 0
var name: String = ""
}
Once the calendarNDays is updated with elements at some point of time I want to modify the name property of i-th element in the array.
Like self.calendarNDays.value[i].name = "Nancy". However, I get the compilation error "Cannot assign to property: 'value' is a get-only property".
What is the way to modify a particular property of an element in a behaviour relay array?
As the compiler suggests the value in BehaviorRelay is a read-only property.
Therefore in order to make changes to the array you first need to copy it and use the accept method to reflect the changes.
Similar to
var update = calendarNDays.value
update[i].name = “Nancy”
calendarNDays.accept(update)
