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.

As the title said. I had done some search but most of them seem for users not for developer.
Any way for checking compatibility or finding breaking changes between iOS versions?
My app is targeting to iOS 10 and now I want to change to 13 for new app upload due to
"Starting April 2020, all new apps and app updates will need to be built with the iOS 13 SDK and support the all-screen design of iPhone XS Max or later."

How to check whether my swift code is working fine in different iOS
version？
You have many ways:
Manual QA.
Run your UI and Unit Tests.
Read your libraries' documentation if there's breaking features.
To explain further, Apple's note, which you seem got a little bit confused of:
Starting April 2020, all new apps and app updates will need to be
built with the iOS 13 SDK and support the all-screen design of iPhone
XS Max or later.
It only means that you should build your app with iOS 13 SDK - which does not necessarily mean you need to make your app/project target a minimum iOS 13.0 version.

I'd like to develope an iOS-app using Flutter. But unfortunately I'm having a Windows PC, so my question is if there are any good working iOS simulators that might be working with the IDE I'm using (intelliJ). Or is it better if I install a VM with macOS on it and develop there?
Thank you for your advice.

You can build your iOS Apps here, but you will not be able to test them on a real device.
The Build System of macOS is required to compile and distribute Apps for iOS and macOS.
If you read the License of macOS carefully, you will recognise that it is not allowed to install it anywhere but on a mac device.
There are workaround known in the community like a "Hackintosh". I would not recommend doing it that way. You will most likely have to buy specific hardware in order to get it going smoothly. For that money, you can already buy a real mac. Note, in order to release the App on the AppStore or test it on a real device, you can not use a "Hackintosh" aswell.
There are Macs out there that come at a price tag starting at around $400, and they are more than enough to build apps and be used for programming. Have a look at MacBook Pros 2012 to 2015 or iMacs from 2013 to 2015, or have a look at a Mac mini. I started this way aswell and I don't regret.
Having said that, building your Apps for Android only is a good way to get started with Flutter.
it is impossible. mac is needed because flutter runs in flutter using xcode build. The ios design can be implemented on windows. cupertinoWidget

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
https://www.dropbox.com/sh/52i59bkony8ke6b/AAD8zZzekK3dY-7EVJnHa6SXa?dl=0
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.
thanks,

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.
