iOS App exports as 32-bit

So i was making a game running on iPhone. Mine has iOS 11.2.5 installed, so i need a 64-bit build target in order to run the game on my iPhone.
I’ve selected IL2CPP and Universal Build in Player Settings and tried to Build and Run on my iPhone.
Xcode however says

Apple LLVM 9.0 Error: Invalid iOS deployment version ‘-miphoneos-version-min=11.1’, iOS 10 is the maximum deployment target for 32-bit targets

What should I do?
I tried to build an XR Project if that helps

DevTK

As quick workaround just set “Target minimum iOS version” in Unity Player Settings to 10.0

That won‘t do it because it still exports 32 bit. And all those apps need to work with iOS11

It really depends if ARKit is mandatory for your app or not. In case it’s mandatory then set minimum supported iOS level to 11.0, and set Architecture to ARM64-only.
Otherwise if AR is optional for your project then pick lower minimum supported iOS level (even as low as 8.0) and it will work just fine on iOS 11.0, because it will include both 32 bit and 64 bit slices. But you need to be careful and allow user to reach AR functions only when running on iOS 11 device, also you would need to check if phone model is iPhone 6S or later.
