Use Size-Class and add size variation for fonts from Attribute Inspector of Label property.

Here are different possible variations, you can set with Size class:

Here is (result) preview of font-size variation, in iPhone and iPad

Update

The result you are expecting, may not be possible using IB (Storyboard) but you can try it with following programmatic solution:

extension UIDevice {
    
    
    enum DeviceType: String {
        case iPhone4_4S = "iPhone 4 or iPhone 4S"
        case iPhones_5_5s_5c_SE = "iPhone 5, iPhone 5s, iPhone 5c or iPhone SE"
        case iPhones_6_6s_7_8 = "iPhone 6, iPhone 6S, iPhone 7 or iPhone 8"
        case iPhones_6Plus_6sPlus_7Plus_8Plus = "iPhone 6 Plus, iPhone 6S Plus, iPhone 7 Plus or iPhone 8 Plus"
        case iPhoneX = "iPhone X"
        case unknown = "iPadOrUnknown"
    }
    
    var deviceType: DeviceType {
        switch UIScreen.main.nativeBounds.height {
        case 960:
            return .iPhone4_4S
        case 1136:
            return .iPhones_5_5s_5c_SE
        case 1334:
            return .iPhones_6_6s_7_8
        case 1920, 2208:
            return .iPhones_6Plus_6sPlus_7Plus_8Plus
        case 2436:
            return .iPhoneX
        default:
            return .unknown
        }
    }
}


// Get device type (with help of above extension) and assign font size accordingly.
let label = UILabel()

let deviceType = UIDevice.current.deviceType

switch deviceType {
    
case .iPhone4_4S:
    label.font = UIFont.systemFont(ofSize: 10)
    
case .iPhones_5_5s_5c_SE:
    label.font = UIFont.systemFont(ofSize: 12)
    
case .iPhones_6_6s_7_8:
    label.font = UIFont.systemFont(ofSize: 14)
    
case .iPhones_6Plus_6sPlus_7Plus_8Plus:
    label.font = UIFont.systemFont(ofSize: 16)
    
case .iPhoneX:
    label.font = UIFont.systemFont(ofSize: 18)
    
default:
    print("iPad or Unkown device")
    label.font = UIFont.systemFont(ofSize: 20)

}
