Human evaluations are difficult, because they are all opinions. Human evaluations are very difficult. Because they are all someone’s opinions. I found it. Human vertical and horizontal evaluations are all stood on someone’s opinions. So that there is no perfect evaluation. If some consultants bring to you perfect human resource evaluation, the consultants are liars.
2020/2/16. The Timer with Swift
I was suffering about how to use timer with swift…
import SwiftUI
struct ContentView: View {
@State var count = 0
func timerStart() {
_ = Timer.scheduledTimer(withTimeInterval: 1, repeats: true, block:{
timer in self.count += 1
})
}
var body: some View {
VStack{
Button(action:{self.timerStart()}) {
Text("Timer Start")
}
Text(String(count))
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
Above code is very easy, but reaching to it, I was very suffered…
Xcode prints too much errors…
