I am currently building an app and would like the option of having users view other users playlists. Is this possible?
Of course this is possible. All this data would be in a database, and you would write stored procedures that would fall in a REST API that you would call from your app. You would need to do the filtering of said stored procedure to show users any kind of data you want (if you only want to show 'friends' playlists, or 'people around you'..etc). Remember, it's just all data. Nothing more. You format the data to look nice, but it's still just data.

I'm building an iOS app with Swift that currently uses Firebase.
Here is what I want to do:
I have a list of items, whenever I add or subtract items from that list I want to send the updated list to all users, they will receive the updated list the next time they open the app.
How should I approach this? Is it possible with Firebase?
I had the same issue
I solved it by making the users download the list each time the user enters the app.
the issue here is that they must be connected to the internet
you can back it up and check: if internet is offline - use the old list in your local database

If I wanted to make an app that allows users to add their own photos to a UICollectionview what method would I use? Also, how could that be added to Firebase's real-time database?
You need to give your users access to the camera and photo library.
You wouldn’t use the Firebase real-time database, you could use the Firebase Storage module, but I would use a product like Cloudinary, which allows you to do nice things like centring, resizing, facial detection etc.

I have simple TableViewController with customers. Every cell has photo, name and phone number. I want to cache this information. So when you will be offline or has slow connection, you will see information from last refresh until data refresh again. Refresh will start every time you enter this screen. I will have more screens, where I will want to cache different informations. I want to ask you about best practice of caching in iOS.
My idea is to use CoreData with Fetched result controller. Is it good idea or not?
if it's limited data you need to cache, you can also consider NSUserDefaults to read - write and delete.

I would like to allow users to send me emails directly through my app, and am wondering if this is possible to do?
Your best and most simple way is to bring up the send email view (or even mailto:) with your app specific email to receive comments and requests on.
Another option is to design a web page that has a couple of fields for information and then hooking it up with PHP.
Just about anything works, it all depends on how you balance user experience and easy of implementation.

I am developing an eCommerce app for iOS. I want to display recently viewed products in one of my app's views. I want to do the same thing that eBay did in their iOS app. Whenever I viewed some product or searched for a product, it showed in a recently-viewed table.
How can I do this in my iOS app? Any help is appreciated. Thanks.
You need to keep track of whatever products the user views or searches. Keep a list of product ids or whatever is appropriate. Store this list in NSUserDefaults or a database depending on your needs so the data is available each time the app is run.
Use this list to display those products in your "recently viewed products" view.
