I'm trying to figure out how to make an iPhone application allow multiple users (that have it installed) share data among them. Now, the tricky part is that I don't want to host a server at my place (very poor ISP services), so I would opt for an online hosting solution. Next, by data I understand them to be able to, let's say, post a comment that would become readable to all the other users and to see what other users have said.
So, in my mind, I'm thinking of either having a file remotely hosted that could be accessed by multiple users at the same time, or a database of some sort or anything like that.
You haven't given us much to go on -- it's not even clear what your question is. If you're just asking how to go about this, I'd suggest the following steps:
Figure out what, specifically, you want the app to do, what data it will share, and who the data will be shared with. Is this an app that you're going to distribute publicly? Will all users share the same data, or will groups of users share with each other but not outside the group? How big is the data, and how is it structured? Can any part of the data change at any time (like a shared document) or will the data just be updated (like a SMS conversation)?
Decide how you want to host the data. If you'll need to serve a lot of users, you'll want some sort of database. If you'll need to serve a LOT of users, you'll want to make sure that your solution will scale easily. There are lots of hosting companies that provide access to databases like Oracle or MySQL, and that may be enough for your purposes. Or, you might want to look into some of the web services options, such as those offered by Google and Amazon. These can be fairly easy to use and have the advantage that they'll scale very well.
Get to work. You'll probably want to build a very basic version of your app around the same time that you're getting the server side working, so that it's easier to test. Once the server side is working and reliable, you can shift the focus back to building out the rest of your app.

I am developing a full web application...
I am considering using prismic.io to outsource some web content which I will query through graphQL. But I would store personal information about users in a local instance of mongoDB.
Whats the long term benefit? If I can just store all of the content myself through an instance of mongodb which holds it all for me.
This is mostly my opinion, if you're a developer working alone or just with other developers, and are only looking for a place to store data, then you're probably better off not using a CMS. One of a CMSs main purposes is to extend the ability to significantly modify an application to non-technical individuals. For example, building a website for a local restaurant, and wanting to allow them to change their menu, without you having to build out a UI to enable it. With a CMS they'd be able to easily change the text and other content on their platform, whereas interacting with a mongo backend might be a bit less straightforward for them. For a more industrial example, say you have a marketing team, who need to run A/B tests to determine the optimal content for a site, they can perform their tests, and have their changes reflect into a template you set up, without them (and you if you set it up cleverly) having to write any extra code. There are more advantages and disadvantages to using a CMS, but I think accessibility is the main reason reason to consider one, especially long-term.
I'm using swift — and the app needs to send a photo and matching text (that a user submits) to a server so that I can download the photo/text.
Would an existing FTP server that I have setup for my website be possible for this application? Or would it make more sense to do something with a web portal?
During my research, I'm finding options like Backendless, Alamofire, Gold Racoon, and various others. They seem like overkill for the simple task I'm looking to accomplish. Is there some minimal service out there that can automate my simple need? If not, which of these options would you recommend for my situation?
Ideally the setup would be free, but I'd be willing to spend up to $100 or $10/month if the service fits.
I'm new to app development so I'm feeling overwhelmed with the options and not sure how to begin researching. I hope beginner questions aren't frowned upon here — I would really appreciate any advise on what I should begin learning to achieve my goal of sending a photo+text from an iOS app to a place where I can access them.
If there are other questions I should be asking to achieve this, please let me know.
For your case there are two main routes to consider
1. BYOS (Bring Your Own Server)
With this option, you are responsible for creating and maintenance of your own server.
Now you can use various services such as Digital Ocean and Amazon for this.
On top of this, you would be responsible for creating your own database and maintaining it as well. Plus, you would need to write server side code along with client side code (the app) in order to instantiate communication between the two.
The advantage of this is that you virtually have control of everything but I think it is pretty clear how painful this task is.
2: BAS (Backend As a Service) Highly recommended
With this route, you simply have to write the app and let another service handle the server side of things. One of the most common ones is Firebase. Most folks including startups go down this route.
There are a bunch of other services out there.
Two Cents:
Whatever option or service you decide to use, I would recommend you make sure that:
a. The service has a good track record.
You do not want something that might end up getting shutdown in the next couple months. I know it is hard to predict this but certain initial guesses/probabilities can be made.
b. Make sure its community is vibrant.
The last thing you as a newbie wants is to be stuck and have no one to help you. Research around and see the different questions people ask and whether or not answers exist.
When is it a good idea to use more than one DBMS? What are the possible repercussions, and how do you decide when to do so?
I'm currently building an application which runs an analysis on our users' websites and stores it. This allows me to analyze all the data and give them analytics.
Since the data collected from each site is static and varies greatly from site to site, CouchDB seemed like a great fit. But in order to create this system, I'd need to build a user account system which couch is quite horrible at (reserving names, emails, etc has all sorts of problems).
My first thought was to use MySQL to handle the user accounts and CouchDB for the massive amounts of data. Essentially, trying to use a hammer for a nail and a screwdriver for a screw.
Is this a time when more than one DBMS is a good idea?
I don't see anything wrong with using MySQL for users accounts and CouchDB for crawled information.
For the users, you might even consider something simpler, like GDBM
I've searched the web for this bit to no avail - I Hope some one can point me in the right direction. I'm happy to look things up, but its knowing where to start.
I am creating an iPhone app which takes content updates from a webserver and will also push feedback there. Whilst the content is obviously available via the app, I don't want the source address to be discovered and published my some unhelpful person so that it all becomes freely available.
I'm therefore looking at placing it in a mySQL database and possibly writing some PHP routines to provide access to my http(s) requests. That's all pretty new to me but I can probably do it. However, I'm not sure where to start with the security question. Something simple and straightforward would be great. Also, any guidance on whether to stick with the XML parser I currently have or to switch to JSON would be much appreciated.
The content consists of straightforward data but also html and images.
Doing exactly what you want (prevent users from 'unauthorized' apps to get access to this data') is rather difficult because at the end of the day, any access codes and/or URLs will be stored in your app for someone to dig up and exploit.
If you can, consider authenticating against the USER not the App. So that even if there is a 3rd party app created that can access this data from where ever you store it, you can still disable it on a per-user basis.
Like everything in the field of Information Security, you have to consider the cost-benefit. You need to weigh-up the value of your data vs. the cost of your security both in terms of actual development cost and the cost of protecting it as well as the cost of inconveniencing users to the point that you can't sell your data at all.
Good luck!
How does one build a directory of 'Spots' for users to check-in to in a native iPhone app? Or, does the developer borrow data from, let's say, Google Maps?
When you Use data obtained from another network or source, you take a risk that the data may change and or may not be accurate, The data may cease to exist, (more so with google, LOL, one minute they are there like gangbusters, the next they are like "Gone" no explanation no apologies, just missing in action, if your developing an application for a business its always best to use your own data sources.
That may be more expensive but its the only way you will have any kind of control over your application resources,.
You can go both ways, it depends on what you want to do and how you designed it to do it. You can have a prerecorded and static database of spots, or you can update it sometimes connecting to some server or you can do it all dynamically by loading each time data from the internet.
Which one to choose? first you shall design your app having in mind something like:
How many times will these datas change
How frequently will these changes happen
How much will it cost to do an update
and so on
Developing your own database of places is likely to be quite an undertaking (and your competitors have a big head start). Google is beginning to provide their Places API for "check-in" style applications, so you may be able to get in on their beta.
