Is it possible to impose restrictions in Auto Layout from threads other than the main one?

No, changes to Auto Layout constraints should only be made from the main thread. UIKit is not thread-safe, and any interface operations, including modifying constraints, must be performed on the main thread to avoid unpredictable behavior and crashes.
If you need to update constraints from a background thread, you should switch to the main thread, for example, using:
DispatchQueue.main.async {
// update Auto Layout constraints
}
This ensures the interface works correctly.
