I have this array defined inside a class:
var pickOption: [String]?
inside my classes init, I am trying to append to the array:
override init!(reuseIdentifier identifier: String!) {
self.pickOption?.append("aaa")
print(self.pickOption)
}
but self.pickOption is returning nil, why? and how can I fix it?
With first statement var pickOption: [String]? you have just declared the array of type string but never allocate the memory. As this is optional type, it will be nil at the time of declaration.
You need to allocate memory for array before using it. You can declare array as this var pickOption = [String]() and rest of code will do the work!!
You have to init it declare it like this
var pickOption = [String]()
as this line
self.pickOption?
with the optional won't run as in it's moment pickOption is nil
