I'm trying to develop an app, where I want it to be an opportunity for the user, to set the background image, to an self-taken image from the camera roll.
I've been googling a lot about this, but can't really find anything helpful.

I need to use the camera in background mode for continuous taking images.but as per apple documentation, we could not use the camera in background mode. Is there any alternate solution for fetching camera without opening application.My task is that When user clicked one button, app should be close and taking images continuously.Could you please any one guide me to do this task?
As the apple documentation say it, it's not possible:
Camera usage is prohibited while in the background.
And I don't think there is any way to do that.
It's good that apple doesn't allow because it increases risk of apps capturing your moments from background without making you notice. Thus risk to privacy.
In my app i would like (with the user permission) to change their iphone background image. Is it possible? If yes i would like some answer in Swift
The only way to do it is to save the image to the camera roll, so the user can then set it as a background himself.
Is it possible to get current lock screen background image in iOS?
I see some apps edit lock screen background.
Can anyone tell about this?
Unfortunately it's not possible. Apple does not allow you to do this. Maybe you can try using some private APIs, but you can not submit your App to the official App Store.
I need to check periodically if the camera is obscured or not.
I was thinking of doing this by taking pictures periodically and checking them for brightness, if there is any way to let an App take pictures while the App is in background. Apple does this within it's Find my iPhone system, as I've read (taking randomly/secretly photos of the thief). Is there any way of achieving this within an own App?
Or do you have any other idea how to achieve this?
Not in any way while your app is in the background. Here's a list of services allowed while the app is in the background.
You can only, sort of, check the luminosity while your app is active by calculating it from the images you take. Apple does not allow access to the light sensor to apps yet.
is there a way to setup an image as a device wallpaper? Originally I want to download an image, save it somewhere in a picture roll and set it up as a wallpaper programmatically.
google doesn't give me any answer on how could it be done.
Unfortunately this API is not exposed to developers. There is also no URL scheme exposed for developers to launch the Photos app.
You're only option is to display a prompt that tells the user to manually go to the Photos application to set their wallpaper, and indicate how they would set the wallpaper there.
