Thats the last part in my Code:

func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?) {
    if let data = characteristic.value {
        let weight: Int = data.withUnsafeBytes { $0.pointee }
        Label1.text = String(weight) + "Hz"
    }
}

I just want to change the Label in the String with "HZ"

You probably haven't connected the @IBOutlet in the storyboard/XIB correctly. – Peter Warbo Mar 28 '20 at 13:08
How can I do that – DomiAki Mar 28 '20 at 13:10
1) Press ⇧⌘F, 2) Type `Label` and press return, 3) Click on the appropriate Interface Builder search result 4) Remove the dead connection – vadian Mar 28 '20 at 13:16
What you mean remove the dead connection – DomiAki Mar 28 '20 at 13:22
Im not sure but i just have to add an Label in Main storyboard and then add it in the Viewcontroller or? – DomiAki Mar 28 '20 at 13:23
There is a dead (the corresponding outlet is missing) connection `Label` in the class in Interface Builder. Remove it and connect it to `Label1` – vadian Mar 28 '20 at 13:28
you mean this one:@IBOutlet weak var Label1: UILabel! ? – DomiAki Mar 28 '20 at 13:31
I mean in **Interface Builder**. Did you read my first comment and follow the steps? Please read also the duplicate. – vadian Mar 28 '20 at 13:33
ahh ok i know what you mean but how can i remove it and connect it to label1 – DomiAki Mar 28 '20 at 13:36
