** BUILD FAILED ** The following build commands failed: Ld about react-native-fbsdk-next

I don't know. But there is no actual error message here, so there is nothing to go on, I will not make any progress and thus will have to wait for more information.

I just did a build today using this library though, it worked fine. I suggest trying the example from this repo, perhaps with a npx react-native-clean-project first.

It turns out I never added the blank File.swift to make bridging headers. Doing so I'm no longer getting those long errors but when I click on the custom login button component I have:

            <ButtonWithIcon
                iconPath={require('../assets/icons/fb-icon.png')}
                title={'Continue with Facebook'}
                pressEvent={() => {
                    LoginManager.logInWithPermissions(["public_profile", "email"]).then(
                        function (result) {
                            if (result.isCancelled) {
                                alert("Login Cancelled " + result)
                            } else {
                                alert("Login success with  permisssions: " + result.grantedPermissions.toString());
                                alert("Login Success " + result.toString());
                            }
                        },
                        function (error) {
                            alert("Login failed with error: " + error);
                        }
                    )
                }} />

Nothing happens like nothing in the console or anywhere.

Then I tried implementing using LoginButton which I added as:

            <LoginButton
                onLoginFinished={
                    (error, result) => {
                        if (error) {
                            console.log("login has error: " + result.error);
                        } else if (result.isCancelled) {
                            console.log("login is cancelled.");
                        } else {
                            AccessToken.getCurrentAccessToken().then(
                                (data) => {
                                    console.log(data.accessToken.toString())
                                }
                            )
                        }
                    }
                }
                onLogoutFinished={() => console.log("logout.")} />

When I click on LoginButton the app just crashes without any error in the console log or anywhere.

So, I opened Xcode ad directly run the app from there and upon clicking the custom button I get this error:

[native] Exception 'fbMY_APP_ID is not registered as a URL scheme. Please add it in your Info.plist' was thrown while invoking logInWithPermissions on target FBLoginManager with params (
(
"public_profile",
email
),
2816,
2817
)

and

Attempt to present <UIViewController: 0x7fb3dcc581f0> on <UIViewController: 0x7fb3df116650> (from <UIViewController: 0x7fb3df116650>) whose view is not in the window hierarchy.

So I looked for the updated my. info.plist to this:

    <array>
        <dict>
            <key>URL Schemes</key>
            <array>
                <string>fb403240190770482</string>
            </array>
        </dict>
    </array>
    <key>FacebookAppID</key>
    <string>403240190770482</string>
    <key>FacebookDisplayName</key>
    <string>doconcall (DEV)</string>
    <key>LSApplicationQueriesSchemes</key>
    <array>
      <string>fbapi</string>
      <string>fb-messenger-share-api</string>
      <string>fbauth2</string>
      <string>fbshareextension</string>
    </array>

But that also didn't work, then I copied and pasted the info.plist exactly as given in the example and it works.

I am not able to see any actual error message in the info you pasted

I see notices that there was an error message, but where is the actual error message?

How should I find that out? Because I've pasted the entire log it shows when it fails. I'm not able to run the app it crashes with that long log of things in the Bug report section.

I think the confusion is here:

  <key>CFBundleURLSchemes</key>
  <array>
    <string>fbAPP-ID</string>
  </array>

The docs say " replace APP-ID with your App ID" but it's not clear about the format needed here which should be:

  <key>CFBundleURLSchemes</key>
  <array>
    <string>fb403240190770482</string>
  </array>

hence keep the fb and add your APP-ID after that.
