Well, that entirely depends on the API. Android, for example, has a
getPressure() accessor in MotionEvents that returns a float between 0.0f and 1.0f, but the actual granularity of your result obviously depends on the hardware – if the screen can only detect “pressed” vs “non-pressed”, you will only ever get 0.0f or 1.0f.
EDIT: As per Julio Gorgé’s answer, iOS does not offer this functionality.
EboMike already answered correctly your question regarding Android devices. For iOS, I can say it does not expose touch pressure information through public APIs at this moment.
There’s a workaround for iOS. See my answer in Tap pressure strength detection using accelerometer
