I don’t understand why it doesn’t work for anyone, I can attach a video of installing and running this application from Testflight. i tested on iphone 12 pro max iphone 13 pro and iphone 14 pro max try using GoogleARCore it seems to work on ios but i’m not sure. ![3v7nth](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/f/7/3f729433c5cb620d719f6f39fc7d561d3c3f24c9.png) ---

I believe your demo video was distributed, I see the yellow dot in the bottom left corner of the app. The Settings I changed in addition to the certificate also have the “Force 32bit Floating Point Precision” option, which defaults to false, which I turned on, because if I didn’t my package would disappear on testFlight Maybe there are some details we haven’t noticed, like plugins? ---

By the way, what I’m doing here in the test certificate app is if I don’t lock the frame rate it will also cause a black screen ---

If you happen to have a 4.27 version of your project (like we did), you can package to iOS Shipping and successfully upload to TestFlight using “4.27 Plus” from the Epic GitHub. Follow this video EXACTLY for proper setup [How to source build unreal engine 4.27.2 in 2023 full step by step | Tutorials |UE4.27.2 |SourceUE4 - YouTube](https://youtu.be/zV-07N5Fd1w) For VS 2019, I checkboxed some additional Windows 10 SDK’s that he didn’t in the video, and then for VS 2022, I had to install .NET Framework 4.8 SDK and the targeting pack (you can do this under Individual Components tab) in addition to 4.6.2. These two things are what got rid of some packaging errors I had. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/8/f/78f96a2b5de4b0fb956dc5f55103445aab218e80.png) Then you need to uncheck “Support Bitcode In Shipping” in the project settings. Then on your Mac, run this command in xcode to create a stripped version of the ipa file USERNAME@USERNAME ~ % xcrun bitcode\_strip /PATH\_TO\_IPA\_FILE/YOURAPP.ipa -r -o /PATH\_TO\_IPA\_FILE/YOURAPPStrip.ipa replacing USERNAME with your username, PATH\_TO\_IPA\_FILE with the path, and YOURAPP with the name of your ipa file. Hope this helps someone! ---

Looks like this will finally be fixed in 5.3. Epic has checked in a fix to Github. [https://github.com/EpicGames/UnrealEngine/commit/f996307f1a02a4d695ff82a8cfa34dc096991ed2?diff=split](https://github.com/EpicGames/UnrealEngine/commit/f996307f1a02a4d695ff82a8cfa34dc096991ed2?diff=split) I’ve tested it and can confirm that it works. You’ll need to build your own copy of the Apple ARkit Plugin. But other than that, the fix is pretty simple. -e ---

These should work. Unreal 5.1 = [Dropbox - AppleARKit\_UE5.1.zip - Simplify your life](https://www.dropbox.com/s/ozqy4igua2tjw4d/AppleARKit_UE5.1.zip?dl=0) Unreal 5.2 = [Dropbox - AppleARKit\_UE5.2.zip - Simplify your life](https://www.dropbox.com/s/uw9g62uhtmky49x/AppleARKit_UE5.2.zip?dl=0) as you might expect, no warranties or guarantees or anything. just put them in your project Plugin’s folder. Or you could put it in the engine’s Plugins folder. i only compiled for Mac. but at the end-of-the-day that’s all you really need. -e ---

Can you please explain the entire process of how to apply this fix for Windows, for UE 5.1 or 5.2? Is it actually possible to manually fix this bug? Thanks!!
