I developed an iPad Game Application and uploaded it to the App Store. But they rejected as it crashes only on iPad Air with iOS 7.1.2.
i couldn't replicate the bug/crash in iPad Simulator. As i dont have an Physical Device, is there any alternate way to test the application other than physical device & simulator ?
crash Report:
you can find the crash report in the below link

Crash may cause from the following reasons in your case -
Are you using any web-service or doing any activity which requires internet? If yes, then be sure that there is network available before calling or sending request from or to a server.
It may also happens if your iOS deployment target is less than ios7.1. So you need to check your deployment target too Under Build settings Tab, in Deployment section.

A while back, I remember putting several of my apps on to my iPhone. However, once I upgraded my phone's software, none of my apps worked. I had to reinstall them with the new version of Xcode. I recently published an app, and I'm not sure if it'll crash when iOS 9.3 comes out. I would not like that to happen, and I want to know what I can do to fix it. My Xcode project currently allows all softwares about 9.0.
Edit
So people were confused what I was talking about. Here is what happened
I had Xcode 7.0.1 or something and my phone was 9.0 My apps that I built into my phone worked fine
When I upgraded my iPhone software, my apps crashed. They did not open.
I published an app into the App Store
I was wondering if my app would crash when iOS 9.3
Hope that is more specific.
Edit:
It was fine
Only with that information is hard to know.
However, it is rare to crash between .X versions, and even between iOS8 and iOS9 it was rare to crash with older versions. Usualy older APIs are well supported.
If you want to be sure you can always install the beta.

I am learning XCode. Soon I will have to test my apps in a real device. I have a Mac but not an iPhone. I suppose I have to buy something. Is the iPod touch a good option to test my first apps?
I am not asking an opinion. This is just a technical question. Is the iPod Touch technically capable to be used with XCode to test, is it a correct tool for a developer?
You don't need a physical device until you need to test some basic features like "Calling...", "a camera to take a photo/video", "motion detections", "user's location"... and the things which you can't expect from a "iOS Simulator". Xcode (of course Apple) provides some simulators (few may call it emulators) for different devices like iPhone, iPad, and iWatch. So at initial "for only learning purpose" you may remain on it, once you get familiar with iOS development, you can purchase an iPhone (or iPad and not iPod). For me, if I'll own an iPhone then I can use it as my personal phone too. For iPod – you can't make phone calls or send message through your network. If you own an iPad then you have two options, one with sim or without sim. It depends on you to choose a device.
If you're planning to build professionally on later stages you should go with an iPhone (may be latest).
P.S. However, if your budget is not great then you can buy an iPhone4s (it supports iOS 9). And you can test almost everything on it.
Yes, you can use iPod touch to test, but basic phone functionalities you can't.

I am submitting my app to app store but it's only compatible with iphone and ipod. When I added the app in itunes connect it;s making me submit an ipad screenshot.
Is it mandatory for apps to be universal? How can I get around this?
In XCode Target -> General -> Deployment Info -> Devices should be set to iPhone.
If your app is only supposed to support iPhone/iPod, only upload iPhone screenshots, don't upload iPad screenshots. Same works the other way around. The only time you should upload both is if your app is universal.
It is not mandatory for apps to be Universal, nor is required to submit both iPhone and iPad screenshots, you can just submit your 3,5" and 4,0" iPhone screenshots.
If it's complaining because iPad screenshots are missing, you might want to check in XCode that your project isn't configured as Universal.

Do I need to have an actual physical iPhone or iPad to develop iOS apps with Xamarin?
I am getting an error about there being not provisioning profiles detected.
I know I have to provision a profile to a device. I was wondering is it possible to create a virtual device and provision a profile to that?
I haven't been able to find in the documentation where to do that.
You dont need an actual device to develop for iOS, but it helps a lot.
You can use the iPhone/iPad Simulator but only on a Mac. You also have to install XCode for this. But like you said, you need to create a Provisioning Profile online on developer.apple.com with App IDs or use a WildCard. I suggesst reading something like
this
Yes, you need a provisioning profile for deploying & testing your
apps on a real iPhone, iPod or iPad.
You need XCode, no provisioning profile or such, for an iPhone or iPad simulator. Note: this is not an emulator, it "mimics" only the software on the phone, not the hardware. Like this it's possible that your app may run way different than a real phone or tablet.
Their is another way to deploy & test your app: Testflight. Xamarin Studio supports Testflight directly form the IDE. You should give that a look.

I had an older mac that all of a sudden became "too old" to submit my apps to the apple app store. Now I need to buy a used iPhone for development/testing and would like to save money and buy the cheapest oldest one that I can, but am worried that XCode will say "this iPhone is too old", forcing me to get a newer one. Does anyone know if that's the case?
All hardware becomes obsolete eventually. As of today, Apple requires that iOS apps support iOS 4.3 or later. So you need an iPhone or iPad than can run at least iOS 4.3.
Of course that is likely to change later this year when iOS 8 comes out. Apple may change the minimum to be iOS 5 or even iOS 6.
If you want your dev iPhone to work for at least a couple of years, get one that can run iOS 7. This mean iPhone 4 or newer. But it is should be noted that the iPhone 4 will (most likely) never support iOS 8 or higher. It barely runs iOS 7.
So your goal should be to get the newest phone you can, not the oldest. Otherwise you'll be looking to buy another one next year.
As an Apple developer you need to get used to keeping current. That is Apple's way.
