A better way to deal function with weak reference.

At a Glance

• Function without return value:

  button.rx.tap
      .subscribe(onNext: weak(self) { me in me.showAlert() })
      ...

  is equivalent to:

  button.rx.tap
      .subscribe(onNext: { [weak self] in
          guard let me = self else { return }
          me.showAlert()
      })
      ...

• Function with return value:

  let searchResults = rxText
      .flatMapLatest(weak(self, default: .empty()) { me, text in
          me.searchGitHub(text)
      })

  is equivalent to:

  let searchResults = rxText
      .flatMapLatest { [weak self] text -> Observable<[Repository]> in
          guard let me = self else { return .empty() }
          return me.searchGitHub(text)
  }
