I would like to know what "consume an API" means in a less technical language possible and would like too some simple example in git and, if possible, using Ruby. I understand that I may be asking a lot, sorry for that, but I can not understand 100% of the examples I found.
I can not go on, because I have not yet been able to fully understand the subject.
Example:
I have a application, a CRUD simple and a API isa JSON that extract the results this CRUD?
Sorry for my limited understanding. I would very much like details with code example, just something basic.
It means that you take in data from an external source/url and do something with it. Here is an example:

In my app the user should be able to search other users that are stored in Firebase. Pretty much like Instagram for example. Tragically I found out that this is not quite possible in Firebase yet. Most of the posts I found about this were older, so was there anything added that could help me out here?
I thought about this:
Right now I have stored all`users with their information. When starting the app I could retrieve all usernames and store it in a variable and then work with that. But this is rather brute force approach... I figure I am not the only one with that problem, so does anyone know what I can do here?
I hope this question is conforming all guidelines, correct me if not.
If Firestore isn't adequate for the kinds of queries you want to perform, your only real alternative is to duplicate that data into another database that can do it.
You will have to come up with some options on your own, as requests for offsite software products are off-topic for Stack Overflow.

I'm currently working on an app that needs to communicate with a secure system. I need to generate a public and private key according to a couple of requirements. According to system specs, the key derivation iterations is required to be set to 1000, but I can't find any way to do this on iOS.
Can anyone help me out? Thanks!
As stated in comment, your question is a bit too broad. I am guessing that you are asking about PBKDF2.
You can use CommonCrypto to do that. I used it with Objective-C and it was relatively easy. I think there might be some difficulties to use it with Swift, but Google search has a lot of info how to do that.
You will need to use CommonCrypto function CCKeyDerivationPBKDF - link to docs. There is a round parameter which I think is what you are looking for.
This question might help too.

What I have researched about hashes doesn't make them that much clearer to me... what I see is a new [THING] that I cannot see the value in right now. I would RTFM if I could find one worth a beans instead of asking... here is what I was wondering...
I've been looking for answers for a few days now with now avail
Where the heck is a syntax manual for Ruby and further more RoR.
What are these things good for...
I know twitter somehow relies on something of this nature but what is exactly
There's a wealth of information out there, http://ruby-doc.org/core-2.3.0/Hash.html for example is pretty clear on what hashes are.
You need to get your head around some of the basics, there are plenty of tutorials out there, https://www.railstutorial.org/ is one that comes up often, http://guides.rubyonrails.org/getting_started.html is the most obvious place to start.

Can anyone help me with few indication about best way to do few things.
At this point I am in a situation where I have a task(.rake), and the code become so ugly that I need to split it out. So if I will create another file, probably a module with multiple classes and methods or just methods, where should I put the file (libs probably?)? (this file may be used by models as well). Also if I want to do the same or a module?
Any books, tutorials, articles, and opinions are welcomed.
Thank you
Check out the Rails Guides for an introduction - beyond that, there are many different [opinionated] resources on the matter, ie:
Railscasts

Does linked data applications use tagging for easier information retrieval? Where to get information on this specific topic?
For semantic annotation (tagging) the following applications would be good starting points:
http://gate.ac.uk/
http://www.ontotext.com/kim
Especially the GATE system includes a lot of information and tutorials related to both POS-tagging and ontology-based semantic tagging.
And yes, once your text has been semantically tagged, it is much easier to connect it to other pieces of text using the extra semantic medatada.
