No Space in Method Call Violation: Don't add a space between the method name and the parentheses. (no_space_in_method_call)

Question

I have many such warnings in the code:

"No Space in Method Call Violation: Don't add a space between the method name and the parentheses. (no_space_in_method_call)"

although there are no spaces and square brackets there, what could be the problem?

example

DispatchQueue.main.async {
    self?.StartActivityWithIgnore(activityIndicator: (self?.activityIndicator)!)
}

An attempt to create a similar function was unsuccessful.
