Should I init a struct or is it valid to get data from non initialize one in Swift?

Question

I have a struct which just contains some static let data. I Use it as storage for cleaner code and separating function parts from static data which is huge ... something like following code:

    struct XtraStates {
        static let clickMovePlus: [() -> (States.Action)] = [
            {.scaleTo(.small).speed(dims.anim.scaleTime)},
            {.visibility(.hide).speed(dims.anim.hideTime)},
            {.noAction.duration(1)},
            {.clickMove},
            {.visibility(.show).speed(dims.anim.hideTime)}
        ]
        
        static let clickMoveForce: [() -> (States.Action)] = [
              ....
        ]
        
        static let allMouseEventsActivate: [() -> (States.Action)] = [
            {.localClicks(.activate)},
            {.localMouseMove(.activate)},
            {.globalClicks(.activate)},
            {.globalMouseMove(.activate)},
        ]
        //..... And goes on .....
  }

• I can read data from it by calling XtraStates.clickMovePlus and it works perfectly but I wonder is it a valid way?

• does it init itself every time I get any data from it or it will never get initialized?

• what will be the difference if I initialize it like static let xtarStates = XrtaStates() and read data from initialized one?

• also which method is more efficient in term of Speed And Memory/CPU usage no matter how small it is?

• and finally will be any difference if I keep these data in the Class/Struct which use them most of the time?

Thanks
