I am currently using Crashlytics in my app and it's working well. However, we are thinking of using NewRelic on the backend to better be able to pinpoint issues in our platform. The NewRelic mobile library has a crash reporter built into it as well (that can be opted out of).
I am assuming you don't want to use two crash reporters considering one will trump the other, however, I haven't seen any information on this anywhere and would just like to confirm.
Additionally if you could explain why along with the answer that would be very helpful.
You can only have one signal handler installed. The last one that registers "wins".

I've been struggling to find how I could potentially implement a simple (iOS) app that would be able to block all connections to a specific domain (to prevent the user from accessing a specific social media platform for example, even from another app).
The information that I have found so far is that I should probably create a Packet Tunnel Provider within a Network Extension and ask the user to add VPN configurations, but I haven't found any example code that would show exactly how to implement this.
Do you have any idea how I could do that in a simple way (block all connections to a specific domain)? Is there a framework/library that I could use to do it easily?
Thank you!
Well, it would not be easy, but you can do it.
Sample code from Apple could be found here and here. This project is for iOS, but it may be on deprecated Swift version, so you will need to do some work to launch it now.
The part you are interested in the SimpleTunnel sample is FilterDataProvider and FilterControlProvider, other things you can omit, because the purpose of this sample is to demonstrate a lot of abilities.
There is also a sample for macOS that is more focused on your needs, and macOS SDK is alike to iOS, but less powerful.
You may want to see this video to sort things up in mind.
There are a lot of firewalls solutions for ios and mac, and some of them are opensource

You will need a developer account, a network extension capability assigned to an application identity, and proper network extension entitlement file a to run things up.
There is a way to sign it manually for development without account&capability, but to distribute you will need it anyway.
For some restrictions you may be needed to install MDM profile on the device.
Is it possible to create an API inside an iOS app to let 3rd party developers create app add-on that are downloadable for users inside the app?
I could not find any ressources for this topic online.
I think that's going to go against the app store guidelines if your intention is that the 3rd party developers write code, which will be downloaded and executed.
There's something of a grey area between legitimate uses and illegitimate uses of downloaded code:
Legitimate Example 1: Something like Hopscotch where children are creating simple fun shared games. These can be considered user generated content.
Legitimate Example 2: A game which is driven by scripts allows for the run-time downloading of patches to fix bugs in the scripts or even to add new levels. I believe such usages have been rejected occasionally in the past, but are generally accepted these days.
The relevant guideline from the guidelines is (emphasis mine):
2.5.2 Apps should be self-contained in their bundles, and may not read or write data outside the designated container area, nor may they download, install, or execute code, including other iOS, watchOS, Mac OS X, or tvOS apps.
And the all-encompassing:
We will reject apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, "I'll know it when I see it". And we think that you will also know it when you cross it.
If your idea is to create some sort of app-store within your app-store app, then I would abandon it immediately, because that's going to be way over Apple's line.
That said, you haven't given much detail about your app, so I might have made wrong assumptions about where you're thinking of going.
I'm currently looking for a way to track user activity. I'm working on an IOS app using swift and i need stats of apps usage. basically I want to get-make a tracking of the used apps. Data like opened apps, start time and shut down time... I know that for get all stats, maybe is necessary run a backgroud service, but, this is another problem that i think to solve after. for now i want to know if it's posible, if there is some way to get stats for used apps. I know that the UIApplication class call the UIApplicationMain function when an app is launched. Maybe, from my app, there is a way for access this info?... Thanks, i have been a long time reading but really, i can't see some clear option.
If (as David has interpreted your question in the comments) you are trying to track usage of other apps that aren't yours, he's right; you can only track your own app's usage.
If you are needing to track events in your own app, there are a good number of analytic frameworks available to do exactly what you are needing to do.
Flurry is one I've used in the past with success, and is one of the more well know solutions. I've also utilized Google's analytics framework. Both are pretty straightforward to integrate into your app and to track the sort of fine grained events you are looking to capture. You can't go wrong with either one of those.
Here is a (slightly old) list of additional tracking/analytics options beyond Flurry and Google's offerings.
You can record your feedback and user experiences, and bug reports with lookback.io
Is it possible to interactively remote debug an iOS App with xCode (or some other interactive debugger, if necessary)?
Has anyone got a neat framework I can stick in my App that will allow this? I can imagine Apple might not want this for live Apps, but for enterprise deployment and for Beta deployment, it would be ace.
A workflow that might work is a customer with a bug can get in touch and then I can email them with a link that will launch my app and connect it to my debug server. With magic.
There's an S.O. question from back in '11 about this – I'm hoping things might have moved on. However, a post here suggests it's probably not possible.
I want to be clear crash reporting, log acquiring and analytics are all very nice and everything (you're right – I use them too), but that is not what this question is about. Thank you :-)
Definitive answers along the lines of "This is just not possible because …" or, "It's possible but fearsomely involved because …", or ideally "Yeah, it's easy and cool, check out …" would be wonderful.
Thanks.
I think what you are searching is not possible. If you want, take a look at Bugfender, it's a product we have built that helps somewhat to do what you want.
With Bugfender you can get the logs from a remote device you choose, is not remote debugging but for now it might be the closest thing to what you want.
I am pretty new to development for iOS devices with jailbreak. From what I am reading I understand that to be able to do all the cool things which you can't do on non-jailbroken phones you have to hook up to a given class and override some of its behaviour. Since there is no documentation how a developer tracks to which class exactly he should hook?
I imagine that for instance if I wanted to have my app respond to a given event such as phone boot, call hang up or user clicking on an icon I would manually generate the given event and see what invocations have been made. Is this the proper way to track where you should hook your code and if yes how is it done.
Note I am not interested in exactly those events mentioned above I am more interested the approach in general.
There are several approaches:
Disassemble binaries
You can disassemble a binary or just dump classes with something like class-dump.
So, you can see the whole hierarhy of classes.
Find dumped classes
Most of major iOS subsystems were dissasembled by somebody already. You can find quite a lot of useful stuff.
As example. Google search "Springboard headers" got this
Dump classes in a runtime.
