iOS 12 support and fix bugs

[NguyenASang]

Fix lag when changing brightness and brightness changes after respring

First, I don't have any devices with iOS 13+, so I need someone to test it on other iOS.

Before (actually not as much as the video, just slightly):

IMG_8413.MP4

After:

IMG_8414.MP4

One problem I have is after respring, the glyph and value of slide aren't updated immediately. I don't know if the problem is my code or yours because I don't have any device to test.

[NguyenASang]

It was my fault, fixed it. Still need someone to test it on newer iOS version before merging.

Cheers @NguyenASang thats a great set of contributions! I'll test it out in the coming days on my iPad that is still jailbroken on iOS 14 and i have to find other testers for iOS 13, 15 & 16, as i can't risk breaking compatibility for these platforms.

In the meantime i would like to make a test build on Github Actions - is there any way you can request to let your forked code make a CI pipeline run? I can't find any information on how to request them, just how i can approve them (https://docs.github.com/en/actions/managing-workflow-runs/approving-workflow-runs-from-public-forks).

[NguyenASang]

I'm not really sure how to do that. However, I just noticed that I haven't enabled the workflow on my fork, maybe that's why you can't run it?

[jschiefner]

@NguyenASang Did you enable workflows in your fork? if not please do and let's see if i can then approve it somehow.

[jschiefner]

@NguyenASang i enabled workflow runs for Pull Requests, please merge the main branch into your feature branch and push, i hope this should trigger the workflow. Also enable workflows in your fork settings if you can first.

[NguyenASang]

It worked! But failed, I will try to fix

[NguyenASang]

@jschiefner Done.
