Add splash screen for iOS
Apple guidelines are different from Android https://developer.apple.com/design/human-interface-guidelines/patterns/launching/
I would prefer the app without the splash screen on Android. A splash screen offers the user no real added value. The delay is not terrible but definitely noticeable. If there was a way to turn it off, I would do it immediately.
It seems that the map does not load in the background. Would it be possible to load the map in the background and then exit the splash screen?
The splash screen is shown when the app loads into the phone's memory. Removing it would simply show a blank screen and would not speed up the app.
If that's the case, I don't have a problem with it. I tried an older phone and the duration seemed pretty similar, so I thought it was an artificial delay.

I find these guidelines interesting, considering how probably every Google app in existence along with a few other apps (including iOS' GoMap OSM editor) have a splash screen.
Apple Human Interface Guidelines discourage using splash screens, and they do it for a good reason. It is better to implement a launch screen, which shows a part of user interface available without loading anything else (e.g. a tab bar with no content above it). Here is a good explanation of iOS best practices for launch screens:

In this fashion, a good launch screen for iOS would look something like that:
If it can ne animated maybe show a loading indicator on the map as well.
