Xcode 10.2.1 and iOS 12.3 beta - ios

Updated Xcode to 10.2.1
Have a customer who is having an issue with my app on iOS 12.3 beta
Xcode 10.2.1 does not have a simulator for the 12.3 beta
How can I install iOS 12.3 beta as a simulator in Xcode?


Only Apple can provide new simulator iOS deployment versions to Xcode. For you to test your application on iOS 12.3 Beta, you will need to install your application on a physical device with that specific OS version or wait for Apple to introduce new iOS deployment version to Xcode.
UPDATE (2019-08-09):
What you could do is install beta software on your Mac (beta macOS version and beta Xcode version) and beta software on your iOS device (iPad or iPhone). Beta Xcode version usually always has upcoming iOS versions available for you to test, either on simulator or physical device. As of this update iOS 13 and iPadOS are available for beta testing.
Beta software can be found here.


I am having the same issue w/app crashing on iPad running 12.3.1 on wifi.
The below has not helped me yet, maybe it will help you;
To find all simulators you can run => xcrun simctl list devices
scroll to top to see available devices.
To run say iPad (6th Generation) => react-native run-ios --simulator="iPad (6th generation)"

How to install iOS 9.x Simulator on Xcode 11?

I'm developing and iOS app with iOS 9 support, but with Xcode 11 update I'm missing the possibility to add / install iOS 9 simulator.
Is there any chance to have iOS 9.x simulator in Xcode 11?

It seems iOS 9 simulator is supported by Xcode 11, but only on macOS 10.14 Mojave. After upgrade to macOS 10.15 Catalina, this simulator is not supported any more.
Though I didn't find confirmation of this in any release notes. The only acknowledgment I found is this tweet by Apple engineer: https://twitter.com/xenadu02/status/1140093901438689280?lang=en

I tried installing Xcode 10.1 on my Mac, but it also did not work for iOS9, i suspect it has to do with Apple dropping support for 32 bit applications (like iOS9)

iOS 9.3 (9.3 - 13E233) - com.apple.CoreSimulator.SimRuntime.iOS-9-3 (unavailable, The iOS 9.3 simulator runtime is not supported on hosts after macOS 10.14.99.) (unavailable, The iOS 9.3 simulator runtime is not supported on hosts after macOS 10.14.99.)

I've got macOS Catalina 10.15.5 currently installed and the only solution I found to test my app on iOS 9 simulator it's described in the following steps:
create a virtual machine with macOS Mojave 10.14.4 (following steps are done into the virtual machine)
install Xcode 10.2.1
Download and install the simulators you need from Preferences/Components
install Xcode 11
Now you should be able to test your app on iOS 9... kind of

How to launch app using Xcode 7.1 with iOS Deployment target iOS 7.1?

I want to launch my app for users who have iOS 7.1 and ahead. After installing Xcode 7.1 after running on iOS 7.1 simulator its giving
The iOS 7.1 simulator runtime is not available.
Unable to open liblaunch_sim.dylib. Try reinstalling Xcode or the simulator runtime.
After reading solutions of
How can I run the iOS 7.1 Simulator in Xcode 7.0 beta 2?
As you can see in comments also with El capitan and Xcode 7.1 its not working.
The only thing which i want here is my app should be available for iOS 7.1 and ahead users.

You will need a device with iOS 7.1 to check your app. If you have deployment target set to 7.1 it should run on that device with no problem.

Older Simulator runtimes are available for download through Xcode's preferences.
Goto Xcode -> Preferences -> Downloads to see the list of compatible legacy simulator runtimes.
El Capitan supports iOS 8.1 and newer runtimes.
Yosemite supports iOS 7.1 and newer runtimes.
There is a known issue mentioned in the Xcode release notes which prevents the iOS 7.1 simulator runtime from working in Xcode 7.
Thus, you can't currently use the iOS 7.1 simulator runtime with Xcode 7.
