Legacy ionic 3 app build problems with branch-cordova-sdk

[newuser44]

Been having this problem for weeks now.
A legacy app that is on ionic 3. Have updated to cordova iOS 5. Could be other programs that our outdated too? Been trying to get things to build with

Trying to do fresh set up.

cordova platform add ios@5
Using cordova-fetch for cordova-ios@5
Adding ios project...
Creating Cordova project for the iOS platform:
    Path: platforms/ios
    Package: com.app-MWA-Carrier.test
    Name: CarrierControl
iOS project created with cordova-ios@5.1.1
Installing "branch-cordova-sdk" for ios

    at /Users/sbrothers/work/appRelease/mobileapps/carrier-control/plugins/branch-cordova-sdk/src/scripts/lib/xmlHelper.js:5:18

Each time I try something else I get a different error. I'll keep posting what I find. I think my next step is to remove branch.

UPDATE Remove branch plugin, can get iOS to build. Things are working correctly.
Add to config.xml

Build again different error.

The plugin does show up in the plugin folder.
Try to build again.

Building for DIT

Build is all screwed up. Have to start over adding and removing iOS to fix this.

What is going on?

Update again.
Add and remove Branch plugin from command line. Got error below. Even tried it all again using the @4 flag. I think both times its downloading the latest.

Do my build. Getting this in the log

Any update? Getting the same problem and searching the web for a solution. Google brings me back to my own problem from months ago.

Adding platfrom iOS auto address all the plugins which seems to cause a problem for Branch io.
Please advice?
