Slow load on iOS when using Unity 2018, but not seen when using Unity 2017

I created a simple project that only has 1 cube, 4 spheres and a UI text label. When I build to iOS with Unity 2017.4.13f1, the scene loads as expected. However when I build the same project with Unity 2018.2.13f1, after the Unity splash screens goes away, there is a noticeable delay before the text shows up over the 3D objects in the scene. This project has no scripts or other assets imported, so it is strange that there would be this noticeable of a delay when the scene loads on the phone. This does not happen in the editor. Thoughts? This has been tested with both versions of Unity and on iOS 11.4.1 and iOS 12.0.1 with the same results.

I noticed this on a larger project and after hours of searching which plugin or script might have been causing it, I started with the simple project I described above in 2017.4.13f and then upgraded it to 2018.2.13f1 and saw the delay in loading.
