Can an app in development affect other apps on the phone? - ios

I am having this weird issue while developing an app on iOS 10. Since I started testing it on my iPhone, other apps I have such as Facebook, Slack, LINE or Google Photos get randomly signed out quite often, like multiple times a day.
Could this be related to my app at all? It uses UserDefaults and Keychain to handle user log in/out within my app. I have a feeling that those two might have something to do with this but I'm not so sure.
I read that this was an issue when iOS 7 first came out but I found nothing regarding iOS 10. So I think it's just me.
Thank you for your help.

Unless there's some obscure bug in iOS 10, there is nothing you can do in your iOS app that can affect any other app. That's the whole point of sandboxing. One app can't mess with another.
This assumes your iOS device is not jailbroken and you are only using public APIs in your app. If you are using private APIs or developing on a jailbroken device, then anything is possible.

What are iOS development limitations in data collection?

I know that iOS's development restrictions are harsher than those of Android, especially those concerning with privacy (ex: application usage tracking). There is allegedly only one iOS application that allows application usage tracking, which is Moment https://itunes.apple.com/us/app/moment-screen-time-tracker/id771541926?mt=8 .
I'd like to know if such limitations on data collection in iOS are only imposed on the app store, or even mere iOS development.
Thank you in advance.
#Jiyoun As far as my experience in iOS Development, you've more space for playing in iOS development than publishing app on Appstore. Thats why Jailbreak still exist and still in news.

Is it okay to use my own app from my own device which contains AdMob advertisements

I have implemented an iOS application which has AdMob advertisements in it.
As far as I know if you don't identify your device as a test device during the development phase, Google finds it out and suspends (temporarily or even permanently sometimes) your account.
My app is live on AppStore now. Can I use my own app? Since I used my iPhone as a test device before, I am a little bit worried about it.
Thanks in advance...
Once the app is in production phase and live in the app store, you can use it as any normal user would. However, you should refrain from clicking the ads multiple times as that would lead to click fraud.

Do I need an iOS device to test PhoneGap Built apps?

I'm a complete noob and figuring out all this as I go along so bear with me.
I've built an app using jQuery Mobile, used PhoneGap Build and it works totally fine on Android and I'll deploy it soon. I'm now trying to figure out the more complex steps towards getting it ready for the iOS market. I've got my developer account set up and have tested my app as built with Xcode 4.2 and Cordova.
What I'm having confusion over (well one of the things) is whether or not I need an actual iOS device in order to get the proper provisioning and certificates. Can I get those, run the package through PG Build and then test it with the Xcode iOS simulator? Must I bother my friends to give me one of their iPhones to test on?
If I'm being vague or asking this the wrong way I apologize.
I'm currently building an app for iOS using Phonegap and even though I have done some testing with a physical device I have seen that the simulator works really well. I mean it would definitely be a good idea to at least run one test of your final version on a physical device before you decide to submit, Apple and pretty much everyone else very strongly suggest that you do, but you aren't required to test on a physical device. All the provisioning and certificate stuff can be done through the Apple Developer site.
The only real reason I could see your app not getting approved relating to this topic is if there is some weird glitch that is only present on a physical device and looks fine on the simulator.
And keep in mind, though it probably won't get you disapproved I've noticed that Phonegap apps that use jQuery Mobile tend to be more glitchy on the transitions compared to when they are run on the simulator.
No you don't need an iOS device to get certificates. You can get them using OpenSSL. I created a GUI to help do just this for Windows users.
However Apple is one of the strictest in approval. It takes 8 days for them to approve an app. And they have been know to not approve apps simply because of there appearance.
Now I myself prefer to have iDevices to test apps.

You will need an Apple computer to submit apps to the App Store. Apple no longer has a web based App Submission

How can I send my iOS app to my client for them to use it?

I've been developing an app using Titanium Appcelerator, until now I've been previewing it using the iOS Simulator and my iPhone.
Now, I want to send my app to the client so they can use it on their iPhone. How can I do this?
Bear in mind this is my first iOS app and so I am not fully au-fait with the terminology or process in making an app go live.
There is no Apple provided mechanism for achieving this, however apps like TestFlight provide a good mechanism for this. You have to register your clients device in order to allow them to install your app. Yes, this should work for Titanium.
You can find out how TestFlight works here:

Create an iPhone app for personal use without using Xcode or going through the App Store

I want to make a little app just for me. I don't want to distribute it, and don't want to make any money from it, I just need to have this app with me.
I don't have a Mac capable of running Xcode, and I don't want to waste any money on the developer license.
Is there a way I can make an app for only my personal iPhone 4s, without going through the App Store or using Xcode? My iPhone is jailbroken.
A web app might be a better solution.
The short answer is no. You would need a Mac/Xcode to compile/build the application for you. As #Thalecress suggested you might be better off building a web app.
Also check PhoneGap, with it you can deploy your web app in several platforms (including iOS, Android and WP7). Phonegap also offers a build service that you can use to wrap the final web app as a native app to run it on a device (PhoneGap:Buld).
