Gesture: System gesture gate timed out.

Forums > SwiftUI

I'm currently learning to program and I've set myself a small app as a project. The app scans the ISBN code of a book using the tablet's camera, compares the code with the Google Books API and displays selected information in a form. The fields are TextFields so that additional data can be entered. These books are then stored in a database. However, I am now faced with a problem: Every time I try the app on the iPad and click on an input field (e.g. it should be possible to assign an individual topic to each book), I receive the following error message in the console:

"<0x102605330> Gesture: System gesture gate timed out."

It then takes about 1 second until the cursor appears and I can enter something. If I close the input and type again in a field, the cursor appears immediately and the following error message appears in the console:

"-[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:] perform input operation requires a valid sessionID"

Can anyone help me find out what the problem is and what I can do about it?


I'm having a similar problem on a pretty basic project setup. My main issue is that it takes a second or two for the TextField to come into focus once I've tapped on it on my phone. I also get this error: <0x101e0af70> Gesture: System gesture gate timed out.

Here's my example with a SwiftUI project set up to use my iPhone when testing. I got some code in ContentView like this:

import SwiftUI

struct ContentView: View {
    @State var text: String = "";

    var body: some View {
        VStack {
           Text("Hello, world!")

           TextField("Pick a time", text: $text)
              .padding(.horizontal, 20)


Anyone ever figure out what's going on here?


I too am experiencing this issue, and don't know how to resolve



I fieldfield especially when I use the simulator is not showing up. Also got this issue written in my console: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem. If you want to see the backtrace, please set CG_NUMERICS_SHOW_BACKTRACE environmental variable.
