Like this:

public var reloadFRCsNeedToPerformWhenFail : [()->()] = []

If you use a type alias to make ()->() a type, you can do it your way:

public typealias VoidVoid = ()->()
public var reloadFRCsNeedToPerformWhenFail = [VoidVoid]()

Or, forego the [] shortcut notation and use the full generic:

public var reloadFRCsNeedToPerformWhenFail = Array<()->()>()
