Apple iOS Build With Unity IAP Not Launching On iPad

Apple iOS build with Unity IAP not launching On iPad but works on iPhone and Android device, I am able to test and complete the IAP pruchase in sandbox environment using TestFlight so I know that IAP is in fact working, but why crashing app on iPad.

On iPad it just shows grey screen, doesn't get to show Splash screen - below are two logs, one from iPad and other from iPhone - both running iOS 13.4.1:

I don't see any errors in the logs and we have heard of no similar reports and possibly limited to your implementation. Please compare with the Sample IAP Project https://forum.unity.com/threads/sample-iap-project.529555/

 

@JeffDUnity3D That's the thing, it doesn't log any info after that as seen in the iPhone build which works. It works fine when IAP is disabled.

Here's where the IAP service is initialised:

@iMancha Please publish, test and compare to the Sample IAP Project https://forum.unity.com/threads/sample-iap-project.529555/

 

@JeffDUnity3D

1. Downloaded sample, followed dialog to update API dependencies.
2. Created Project link to Unity Services, Analytics and IAP were already enabled as per samples settings.
3. Deployed to iPad, same issue(grey screen) but log has even less data(well it stops at UnityIAP UnityEarlyTransactionObserver: Added to the payment queue ):

What iPad version and iOS version? Unfortunately we don't have a quick solution for you.

 

iPad 6th Gen iOS 13.4.1 - tested with WIFI/NO WIFI. same result.
iPhone XR same OS version as above- WORKS

 

The issue is only on your iPad?

 

Yes, only iPad. updated previous reply.

 

Hi,

Sorry for necro-ing (kinda), but we are encountering an extremely similar issue where our app freezes at launch (before the Splash Screen) on one specific iPad, and were wondering if there was any update on this?

For reference, we run our application on a lot of devices, and only one (an iPad Air 2 running on OS 13.5.1) has this issue. Only on this device, when we run our application with the "Debug executable" off (from Xcode's scheme window), our app doesn't load and infinitely stay on a gray screen. The same result is obtained when using a version of the application which went through either Testflight or the App Store (which is problematic)

We are mainly using Unity 2019.4.13f1, but have confirmed that upgrading to 2019.4.20 didn't fix it.

The only 'application logs' we get when running are the same 2 cited on this thread's first post :

1. UnityIAP UnityEarlyTransactionObserver: Created
2. UnityIAP UnityEarlyTransactionObserver: Registered for lifecycle events

We tried to check the entire devices logs around the 'freeze moment', but didn't get anything useful (device logs attached, the Unity IAP ones are on lines 1643-1644)

We know for a fact that this bug is not present on some others iPad Air 2 running the same OS version, but this only makes it harder for us to pinpoint, or event know how many users / devices are concerned.

Any news or help about this bug would be welcome!

 

Does it work correctly with a test app without IAP?

 

@ArthurMWM Check your network settings / proxy settings and provisioning of the device for use by testflight.

Not that I know, only speculating after reviewing the logs for piano-app, after those UnityIAP lines, there are logs talking about a Web exception, and SOAuthorization which is in a "AppSSO" framework (I never have used). Based on that I guess there could be a single-sign-on, or testflight related issue.

 

Having the same problem on an iPad Air 4th gen, running iOS 15.0.1 . The iPad belongs to my nephew and thus has its apple account connected to his dad's account, which could be a meaningful datapoint

Additional Info:
Unity 2020.3.19f1
XCode 13.0

Build runs fine on other devices, including an iPhone 8 running iOS 14.6, and a first generation iPad Air running iOS 12.6

This is the entirety of the XCode log output:
2021-10-17 13:09:16.871885+0200 WordBlocks[1857:96740] UnityIAP UnityEarlyTransactionObserver: Created

@nicholasr , tagging you as the last post in this thread was in March

 

There are no errors in the log that you supplied. As mentioned previously, are you certain it's related to IAP? What is the behavior without IAP installed? Perhaps test with a new/empty project to compare.

 

For reference (since we answered earlier with a problem of ours that seemed similar) - we did find a (quite dirty) patch, in case it helps anyone

The patch being in Xcode
- Select your main Unity-iPhone target
- Go into Build Phases
- Open "Link Binary With Libraries"
- Press +
- Add UnityFramework.framework (the one who's under the Unity-iPhone Project category)

I won't pretend we understand exactly why this does the trick, but we found this workaround here : https://issuetracker.unity3d.com/is...ns-triggers-watchdog-termination-after-launch ; where the symptoms were similar enough to our problem, so we tried the proposed workaround which solved our issue

 

Thanks @ArthurMWM,
Its working for me you saved me.

 

Thanks @ArthurMWM - I was running into the same issue, surprising but also not surprising that Unity does not account for this when creating the Xcode build..

 

Thanks @ArthurMWM !
It's working for me!

 

Thank you, it's working for me
