App getting crash when click on GoogleSignIn button

As the error clearly says, your app is missing support for the url schemes.

Add the following schemes to your info.plist

<key>CFBundleURLTypes</key><array>    <dict>        <key>CFBundleTypeRole</key>        <string>Editor</string>        <key>CFBundleURLSchemes</key>        <array>            <string>***Your bundle ID***</string>        </array>    </dict>    <dict>        <key>CFBundleTypeRole</key>        <string>Editor</string>        <key>CFBundleURLSchemes</key>        <array>            <string>com.googleusercontent.apps.107731993306-6s44u18onibp6gi0ddj94si1aifshhg6</string>        </array>    </dict>    <dict>        <key>CFBundleTypeRole</key>        <string>Editor</string>        <key>CFBundleURLSchemes</key>        <array>            <string>***Something here***</string>        </array>    </dict></array>

Check this url for your id => https://developers.google.com/identity/sign-in/ios/start-integrating

Your info.plist should look like ->

You have to add a URL scheme to your project

1. Open your project configuration: double-click the project name in the left tree view. Select your app from the TARGETS section, then select the Info tab, and expand the URL Types section
2. Click the + button, and add a URL scheme -com.googleusercontent.apps.107731993306-6s44u18onibp6gi0ddj94si1aifshhg6

I got that crash too. But accepted answer did not help me.I have fixed that crash in other way:

Double check that:

In AppDelegate straight DNS:

GIDSignIn.sharedInstance().clientID = "536164374389-ivga9a9at2g31nfmhpvdyhc98yf6afnr.apps.googleusercontent.com"

In Info.plist reverse DNS:

<string>com.googleusercontent.apps.536164374389-ivga9a9at2g31nfmhpvdyhc98yf6afnr</string>
