尝试在标签上打印日志文件（swift4）

Question

My code below is calling coreData to print on a label. If I print on a label it only takes the last entry of coreData unlike what is printed on the log file.

for i in user! {

        print( "color: \(i.username!) Score: \(i.password!)")
        displayL.text = ( "color: \(i.username!) Score: \(i.password!)")
    }

LOG FILE

VIEWCONTROLLER

Answer 1

Try this:

for i in user! {
    print( "color: \(i.username!) Score: \(i.password!)")
    displayL.text = "\(displayL.text ?? "")\ncolor: \(i.username!) Score: \(i.password!)")
}

As you can see I'm concatenating the string instead of overriding it in every iteration
