AR Foundation unity20193.1f Building ios

I encountered a problem when I used version 3.1f of unity2019 to release. When I released ios in xcode, I could use iphone8p ios13.3 to run normally, and use iphone exr ios13.3.1 to flash back after a while. How can I solve this problem to release. When I released ios in xcode, I could use iphone8p ios13.3 to run normally, and use iphone xr ios13.3.1 to flash back after a while. How can I solve this problem，thank you

 

I believe it is a bug that Unity has to patch. I am experiencing the same problem with iOS 13.3.1 here.

 

Hello,

Thanks for replying.
iOS 13.3 target does not show in XCode 11.3. But it still works on 13.3 if i set it to 13.2 as we can see in the image.

This is the error that i get when i try to run it on iOS 13.3.1. It basically quits the app as soon as i run it on 13.3.1. The same setting runs perfectly on my other device which is 13.3.

I am also using the latest version of Unity, AR Foundation etc etc.

Please let me know if you need more info.
Thank you.

 

I use Unity 2019 3.0f1 create a empty project

 

I used the vmware to use mac10.15, installed xcode11.3beta, just released an empty project in unity, and built it to the IphoneXR, the application crashed.Thank you for answering me.Email:yvettezz@126.com

 

I can use xcode11.3.1 to release and run normally, it is good, thanks for your reply, I am not sure if it is a bug

 

Hey, buddy, I've solved the problem, the application doesn't crash anymore, you can try another version of xcode. I'm not sure what the problem is

 

In unity 2019, 2.2f will be released perfectly, which should have nothing to do with xcode

 

It took me two days. In Unity 2019 2.2f can be released to xcode normally, successfully built to the phone, and successfully run, but not in Unity2019 3.1f, my phone iphonexr ios13.3.1.Thank you for your follow-up and help, please take my knees.life F***s us all

 

Hey! Thank you for sharing your solution.

It did not work for me unfortunately. My project was build with 2019.3.
It gave me error because unity doesn't support downgrading projects.
Did you have problem downgrading?
I am assuming that you created an empty project with 2019.2 and it worked with iOS13.3.1?

Also, your video is spot on. The app opens for a brief moment, with a black screen. It then returns to the home page.

 

Yes, I downgraded to unity2019 2.2f, which can be used normally

 

I found this link after some digging.

There are currently 2 solutions for us (and for the 200+ people following that post).
Users can choose to downgrade to Unity 2019.2. Or simply pay for a Developer Apple ID.
