Resolved Launching ECSSamples on iOS, crash immediately

I would like to run ECSSamples in this sample on iOS device.

https://github.com/Unity-Technologies/EntityComponentSystemSamples

However, it crashes immediately after booting.

It crashes at this part of the screenshot on Xcode.
UnityFrameworkLoad returns 0x0.



Not limited to this sample, it happens in all projects that implement ECS.

I also tried it on an Android build, but it works fine.
Of course, it's okay on Unity Editor.



Development environment

• Unity: 2020.2.1f1, 2021.1.6f1
• Xcode: 12.5 (12E262)
• macOS: Big Sur 11.3.1 (20E241)
• Device: iPhone XS Max (iOS 14.6), iPad mini 2 (iOS 12.5.4)

Package version

• com.unity.entities: 0.17.0-preview.41
• com.unity.jobs: 0.8.0-preview.23
• com.unity.platforms.android: 0.10.0-preview.10
• com.unity.platforms.ios: 0.10.0-preview.10
• com.unity.rendering.hybrid: 0.11.0-preview.42

Is it missing something?
Or is it a preview version so it doesn't work?

Thank you!

 

I contacted support and the answer was that it could be built using an older package, so I solved it that way.

@sugiharam2
I am troubled by the crash of the entities 0.17 anroid package.
According to the configuration you provided, I downgraded to the 0.16 pre21 version, but there were 2 errors on unity2020.3, as follows:
Library\PackageCache\com.unity.entities@0.16.0-preview.21\Unity.Scenes\Hybrid\FileUtilityHybrid.cs(33,21): error CS0618:'UnityWebRequest.isNetworkError' is obsolete:'UnityWebRequest.isNetworkError is deprecated . Use (UnityWebRequest.result == UnityWebRequest.Result.ConnectionError) instead.'
-------------------------------------------------- ---------------------------------------------
Library\PackageCache\com.unity.entities@0.16.0-preview.21\Unity.Scenes\Hybrid\FileUtilityHybrid.cs(33,48): error CS0618:'UnityWebRequest.isHttpError' is obsolete:'UnityWebRequest.isHttpError is deprecated . Use (UnityWebRequest.result == UnityWebRequest.Result.ProtocolError) instead.'
How did you deal with it? thanks.

 

@sugiharam2, could you please share your manifest? Seems like other packages should be updated as well.

RESOLVED. In my case I had to downgrade "com.unity.physics" to "0.5.1-preview.2"
