Is there any way (workaround?) with that i can use @environmentobject in a class?

@EnvironmentObject pulls objects out of the SwiftUI environment, which is only available during the render phase of a View. So, no.

I would question why you think you need to do that in the first place and examine what exactly you are trying to do.

im creating a stopwatch app and i have a class for the timerManager, which increases the timer by one. I d like to use some data in that whuich is set in a view.
