Xcode 10.2 does not open after installation from App Store - xcode

When I try to open Xcode 10.2 after installing it from the App Store, it doesn't open. After a while, a dialog box comes with an error "check with the developer to make sure Xcode works with this version of mac os".
Can anyone help? My Mac OS is Mojave 10.14.2

Xcode 10.2 includes SDKs for iOS 12.2, watchOS 5.2, macOS 10.14.4, and
tvOS 12.2. Xcode 10.2 supports on-device debugging for iOS 8 and
later, tvOS 9 and later, and watchOS 2 and later. Xcode 10.2 requires
a Mac running macOS 10.14.3 or later.

SDK Version Issue.This app was built with the iOS 14.5 SDK

ERROR ITMS-90725: "SDK Version Issue. This app was built with the iOS 14.5 SDK. All iOS apps submitted to the App Store must be built with the iOS 15 SDK or later, included in Xcode 13 or later.
My current version is macOs Big Sur version(11.4)
and my xcode version(12.5.1)
You need XCode 13 to use iOS 15 SDK. Simply update your XCode and MacOS (if necessary), then build the app again.
After updating XCode, your iOS SDK will be automatically updated.
Instruction for Older macOS:
Use this patch and upgrade your macOS https://github.com/Ben216k/Patched-Sur
After the upgrade, you can install XCode 13 on your older mac.
Here you can see all the supported mac lists: https://bensova.gitbook.io/big-sur/supported-macs
Below are steps I followed to solve the same issue in the same context:
Upgrade macOs Big Sur -> macOs Monterey v12.4
Update Xcode 12.x -> Xcode 13.x or later
Note: Upgrade could take some minutes. Hence, be patient

Unable to download iOS 11 Simulators for XCode 13.2.1

I'm unable to download iOS 11 Simulators for XCode 13.2.1
what should I do?
You can check supported simulators for specific Xcode version on Apple Xcode support page.
Additionally, as answered on a similar issue, simulator availability depends on the installed MacOS version. While Xcode 13.2.1 seems to support iOS 11 simulators on Big Sur, on Monterey the lowest available version is 12.4.

Is it possible to run on iOS 9.3.1 from Yosemite?

When I try to run from XCode 6.4 I get "iPad may be running a version of iOS that is not supported by this version of Xcode." It won't let me open the Xcode beta either, saying it needs to be on OS 10.11. I need to install an app right now though. Is there a way to do it from Yosemite?
Apple have recently dropped support for Xcode on Yosemite. The last supported version is 7.2.1. If you want to use Xcode 7.3 which supports iOS 9.3 and above you'll need to use El Capitan which is a free update for Yosemite users.

Xcode 3 and iOS 6

A newbie question. I have Xcode 3.2.6 and my ipad is iOS 6.0. It seems this version of Xcode doesn't support the iOS version. What version do I need to upgrade my Xcode to so that I can test apps on devices running iOS 6.
And, my second question do I have to download the .dmg to upgrade Xcode. Currently I am running snow leopard 10.6.8.
For iOS 6 you will need Xcode 4.5 and at least Lion (10.7)
You need OS X Lion 10.7.4 or later to install the latest version of Xcode from the AppStore. Then you will be able to build apps to your device with iOS 6.0.
