Swift4 Daily Boot Time

iOS apps are available when the app is not running or when the app is running in the background.

• Taking action at a specific time
• Use a timer, etc., to perform the processing at a fixed cycle

is not allowed.This is an iOS specification.

Next, I wanted to get the value of how long I was booting up per day.

If you simply want to perform the processing at a certain period, you can set up a server outside and send a silent push to the terminal at a certain period, but is that consistent with the purpose of one no?(I don't think so)

If you disclose why you want to do this (check the daily boot time), I think it will be close to solving one no's purpose.
