iOS: possibility to keep an application always on top - ios

Is it possible to implement such a feature like this in iOS devices, allowing an app to be always on top?
Using private APIs/workarouds is not a problem.

In iOS 6, there is a feature called Guided Access
For details check:

Any way of knowing if bluetooth is on/off without triggering "allow app to access" bluetooth prompt on IOS 13+?

I'm trying to design a flow where if the bluetooth is turned off, then display a specific page, or skip the page entirely of bluetooth is already on. However, I want to do this without triggering this popup on IOS 13+.
I am using IONIC 6 to build the IOS app and using diagnostic.isBluetoothAvailable() to do this. However, this asks bluetooth permissions if not requested.
Is this possible? Thanks bunch!

Can I make an IOS app that can prevent some IOS features?

I am new to IOS development.
I was just wondering if it is possible to make an app that will prevent other apps from being opened or an app that will prevent you from going to safari/settings/etc...
Is Apple (IOS) okay with this? I know Android can be different and allows some of these features to persist.
You can't accomplish this in IOS platform , every app is responsible of it's own constraints , permissions and sandbox
No, it can not be possible. Even if you do it some how, apple will reject that.

Lock iPhone and iPad Screen programmatically

I want to lock screen iPhone and iPad programmatically
I have searched a lot but didn't get proper idea. I have found one app Lock me but it is not worked on after iOS 7.
here is that link
https://github.com/neuroo/LockMeNow
as per my search I think we are able to implement this functionality using private api and using kiosk mode.
I don't think you can programmatically lock the iPhone or iPad from you application. that not full fit the apple policy and its guide line. In iOS app development we can not handle any API that out of the application. Apple not make any API for lock screen that you fire from your native app.
Other things is you are attached one link in your question. that clearly write the limitation that:
This application can obviously not be accepted (as is) on the Apple Store, and that's mostly why I put it here. If you want to use the application, you will need a developer cert (or a jailbroken device and using the iDevice build toolchain).

Need to lock all application on the iPhone by using an app

I am developing an app for one of my client,he wants me to provide a functionality to lock all available apps on his iPhone using this app,but i haven't much idea about it,i know about the screen lock like passcode app but not this one.
Please suggest some best tutorial link.
Thanks
You can't access another app functionality from your app according to Apple guidelines so it is not possible.
Unfortunately, it is not possible to lock the device programmatically. There is no available API for this.
It's not possible, Apple didn't allowed it.
This could've been possible in Android but sorry this is impossible in iOS. Apple doesnt allow that.
It's not possible for an app to lock itself down. However if you have access to the device you can set up Guided Access when the app is open, preventing it from being closed. If you have an enterprise setup you are also able to set up Supervised Mode where you should be able to configure Guided Access over wifi.

Controlling iOS device

Is it possible from my app to run in background, turn on/off other apps, control the iOS device without jailbreaking it? I understand that this app will not pass Apple's review/approval, but I am not planning it, instead, I just need to distribute it to clearly defined list of devices. I just prefer not to require to jailbreak device.. Is it possible?
I believe its possible without actually jailbreaking the physical device. Check out the second answer to this question for some more information. iOS app without developer program or jailbreak
