Not only "swift-algorithms" but also "swift-collections" which is announced yesterday are so amazing library I think.
I wonder why apple didn't include that libraries in official swift.
Maybe you who will answer to me absolutely don't know too.
If you don't know, could you tell me if developer teams of each of library is different with developer team of official swift?
They're both not in the swift standard library (yet) because they haven't passed the Swift Evolution process. This is explained in the Swift Algorithms announcement:
It’s our ambition for the standard library to include a rich, pragmatic set of generic algorithms. We think the Algorithms package can help realize this goal by serving as a low-friction venue to build out new families of related algorithms—giving us an opportunity to iteratively explore the problem space and learn how different algorithms connect and interact—before graduating them into the standard library.

I understand that in order to use Selectors in Swift, one must mark the Swift function #objc and have at least internal visibility because the function must be exposed to the Objective-C runtime.
So from my understanding, when running those #objc marked Swift functions as selectors, Objective-C's core is majorly involved. So I'm wondering will Apple eventually make Swift completely independent from Objective-C as Swift is primarily written in C++?
Thats a complicated question, and only Apple truly knows. I would say no because of how many apps still use Objective C and the fact the some people still use it in new apps. It would be hard for apple to just completely ignore those developers and potentially take massive amounts of revenue away from themselves and other developers, on top of most of their OS still uses some Objective C. I hope that makes sense and sorry if people get upset that you asked this on SO.

I want to go with Xamarin.Forms project. Now, I am bit confuse for consuming Rest API for this project. Performance matters.
There are many available but can any body please suggest me which should be best for Xamarin.Forms(.Net Standard)?
Microsoft Http Libraries or third party libraries like Refit, RESTSharp, PortableRest, etc.
Please suggest
All of these options are viable. I think the performance differences between these libraries will be marginal. So, it mostly comes down to what you feel comfortable with.
I like to use Refit because it will take a lot of redundant code out of your hands and you just have to focus on the contract. All the code for the actual calls is generated at compile-time (and thus won't impact your performance at runtime).
Also have a look at how well the library is maintained and if it's active. If you choose one that is already inactive for a while, chances are that you will start relying on older software versions which might not be what you want.

My boss ia bashing Scala language due to an previous experience with ScalaScript from https://scala.com so are there some relationship between they?
I am trying to evagelize Scala in my company, so it is important to eliminate this misunderstandings.
Scala.com is the home of Scala, Inc. a producer of multimedia software. It was founded in 1987 as a Norwegian company called Digital Visjon. They work with digital signage solutions (commercial or enterprise digital media displays and related scripts and communication, etc.)
They have absolutely no connection whatsoever to the scala language.
Maybe scala.com is related to Scala the language: maybe they use the language internally, maybe their "solutions" are somehow based on the Scala language, who knows ... My hunch is that they are not related, because it they were they would advertise it or change name.
However, Scala the language is definitely not related to scala.com. I had never heard of this thing before.

I recently read through Code Complete, and it recommends that I create a project specification before actually coding.
The book didn't go very far into detail about what 'specs' are, and how they are made. Because this is a crucial part of software development, I would like to know how to create quality specs that are not too exhaustive.
Where can I learn more about software specifications? Or any of the other prerequisites outlined in Code Complete?
Here's Joel's article on Function Design documents.
http://www.joelonsoftware.com/articles/fog0000000036.html
If you are looking for books, I can recommend two right now, and in fact, I ordered a third because it looked good.
The two I can recommend fully are:
Software Requirements (2nd Edition)
More about Software Requirements
I also ordered a third book:
Software Requirements Patterns
Joel Spolsky posted the functional spec to his CoPilot application along with a brief blog post about it.

Developing software solutions which already exist and are available for re-use (either commercial or open-source). AKA "re-inventing the wheel".
Same as above, but your solution being broken. AKA "re-inventing the square wheel".
Developing solutions for problems which do not exist.
Again, I'm interested in a more formal approach, e.g. TRIZ
Doing some research beforehand (1) and investing in solid software architecture (2,3) usually helps :)
When you're planning to develop something you always need to calculate the benefits of doing some and the things like the ROI.
