Building to iPad4 with Unity 2019

Is it actually possible to make a build that deploys to both 32bit and 64bit devices anymore? I have made a build that functions on iOS 12 device but cannot get get it to deploy on an iPad4. No matter what I do, I keep getting these warnings about optimization and stepping but all the google info seems to suggest that I would need to disable Swift optimization w$$anonymous$$ch does not seem to be an available option. I have been trying and trying to get a build of my game onto IPad4 but without success.
