I’m just starting with fastlane and I’m exeperiencing a behavior I can’t explain.
In the Xcode project the build number is set to 703, and when running the lane which updates it it changes it to 585..586 and so on..even if I set it back to 703 every time.
I tried using fastlane run get_build_number and the number does correspond the latest wrong number it did set.

I tried specify a number (703) and now it does increment from there.
I actually did start a fresh installation of fastlane for the project and
I was expecting that it would read the build number from Xcode but it obviously doesn’t.
Where does fastlane actually read the build number from before incrementing it?

Many thanks
