initalizer for conditional binding must have optional type, not int :     if let hrAverage: Int = 
    (oldHR1+oldHR2+oldHR3+oldHR4+heartRate!)/5 {
    
    print(hrAverage)

    } 


    else {
    
     let hrAverage = (oldHR1+oldHR2+oldHR3+oldHR4) / 4
    
     print(hrAverage)

    }

Getting this error that tells us "initalizer for conditional binding must have optional type, not int" I've been stuck on how to get rid of it. I have to unwrap value heartrate using optional binding! help!
