Why is the initial display of WKWebView slow on iOS/Objective-C (Swift)?(Native Gawa, Hybrid)

Gawa Native/Hybrid app development using iOS's WKWebView
Use WKWebView with Objective-C (Swift).
View/Close HTML (web page) in WKWebView with native button tap
Checked the speed of the Yahoo page/"Hello World!" simple page.
It takes between 1. and 2.5 seconds for the display to complete.
Even if it's the same URL, the display speed (display time) varies every time in Repeated Application Launch/Repeated Operation.
The display speed (display time) varies from URL to URL.
How it is displayed is instantaneous after the above time when it is white, and it is not displayed from the read part.
In the app, the screen transition of the app screen is done in an instant, and only WKWebView takes 1.?sec to 2.5sec.

Created a browser app
Enter URL 表示 Display button tap 一瞬 HTML page is displayed in an instant
No matter how many times you try in that state, it will appear in an instant.
一瞬 Moment is so fast that it is impossible to measure visually.

Does WKWebView take between 1. and 2.5 seconds to generate?
時間The reason why there is a variation in time is that what happens when you create it inside the library?

To reuse the generated WKWebView, the generation process is for the first time only.
First time only takes 1.?seconds to 2.5 seconds
The second and subsequent display is instantaneous.= Same speed as browser.

Why can't I find information about slow generation and display of WKWebView?
(There is a lot of information that the display is fast.No fast or slow generation information.)
If the program/use of WKWebView is different, is there a case where the generation/view takes 1.?sec to 2.5sec is displayed correctly?

This is a self-answer.

Generating WKWebView takes a few seconds (e.g., 1.5 to 2.5 seconds タイミング Timing, time varies by terminal).

1. I can't make a definitive decision because I can't find any sentences or information such as "It doesn't take long / it takes time to generate" or "Specifications" or "How to speed up generation / cause of delay".
2. I created a separate test application for this verification, but it is still slow to generate.
3. Swift, Objective-C, and videos of development apps from different countries show that generation takes a few seconds (including some predictions).
4. It's just a supplement."I contacted Apple, but it was ""I can't answer"".":Note: There is a possibility that the inquiry to Apple itself was not answered due to a problem.
