Are there any official documents regarding Sidebars / Navigation Drawers or whatever they may call them, written by Apple? I know that there are no official Sidebar component - I am just looking for any mentioning of Sidebars in official Apple documents (whatever it may say). Want to know how Apple sees these sidebars and if they express any opinion about how and when to use them
The most official response I can find from Apple is in one of their WWDC talks where they explicitly mention Hamburger menus (or sidebars):
"Their value is greatly overstated and they have huge usability downsides".
https://developer.apple.com/videos/play/wwdc2014-211/
(around 31 mins)
There is nothing in the Human Interface guidelines about Hamburger menus, which in itself should imply that Apple doesn't rate them. As is stated in the video
"Typically we don’t provide design advice about the things that we don’t offer".
So although these UI elements may make sense for your app, Apple recommends other approaches to designing your UI and menus.

I have a problem regarding scammers in my app:
In the private chat between users, users may feel comfortable sending nudes or other sensitive information
The other user is a scammer and might screenshot the information and will re-sell it else where or use it to blackmail the user in some capacity.
I can detect screen recordings and if there is an active capturing in progress can hide content
However with screenshots I can only detect the screenshot after the fact but not beforehand to black out content.
Are there any known code patterns or SDKs that assist with this?
iOS doesn't allow it, There are no observers for screenshots before being taken. And you can't do anything about it, Because it's just not possible to stop someone from taking screenshots, both physically and digitally. You might want to look into other solutions to protect user data.
The only SDK I know of is ScreenShieldKit
There's this answer that provides an alternative, but I've not had a chance to test it out.

In the official Human Interface Guidelines Apple is reference the topic onboarding - a neat interface which only pops up when you open the app for the first time.
I‘ve seen this in many apps, yet I can‘t find information on how to implement it. It seems like a standardized interface. Check it out here: https://developer.apple.com/ios/human-interface-guidelines/app-architecture/onboarding/
Can anybody provide some information?
There are no ready-made components in UIKit specifically for onboarding views. You'll have to roll your own.

is there any further documentation of the Here Maps SDK for Swift? I have only found a simple mapView and nothing more.
Thanks for all your tips!
Unless this is what you were referring to, you might find this site useful. It seems to include more extensive topics than just mapViews.
This comes from the developer.here.com website:
Here iOS SDK Documentation
If you're looking for more depth than this, you might be out of luck. I have just performed some research on this topic and it doesn't seem to me that Here has extensive online resources.
This might be from the original site as well, but you can also check out this list of examples for inspiration/help.
Of course you can also refer to StackOverflow as a resource as well, as I have seen some posts about this service that have been posted on the site, so they may help with some of the problems you are facing.

Would be required to port some programming codes on Windows onto PowerPC. The codes would need some kind of optimisation and require the use to Altivec programming.
Would like to ask where to find a good beginner guide to Altivec and any SIMD programming if they would be similar to SSE?
Thanks
You should still be able to find PowerPC and AltiVec resources on motorola.com, ibm.com and developer.apple.com. Also search the [altivec] tag on StackOverflow as similar questions have come up before.
Apple has (or had) a very useful AltiVec->SSE migration guide that you could use in reverse - a quick Google search turned up a copy here.
Note that IBM calls AltiVec "VMX" these days, so you might also want to use VMX as a search term (in conjunction with POWER or PowerPC).

I want to automate the UI Testing of my app.
Please tell me how to use javascripting to automate the process.
Dint get much information after searching on google.
The main resource on Apple's site is the UI Automation Reference Collection which lists the various interfaces, etc. available.
If you click the "more" link at the top of the above link a brief overview is provided, although I'd recommend at least a quick read of a blog such as "How Do I Perform UI Automation Testing in iOS 4" over on The Code Project.
The following is a place for beginners.
http://blog.manbolo.com/2012/04/08/ios-automated-tests-with-uiautomation
One place to look is the UI Automation Reference. It is not really a tutorial but a reference.
In the Instruments User Guide you can read about how to run the scripts. It also walks you through how to script access to elements using the Recepies sample code.
