The base port for LND REST api for the first node is usually 8081. This port seems to conflict with other applications (e.g. local development), but in particular it conflicts with XCode build PhaseScriptExecution which runs on 8081.

PhaseScriptExecution Start\ Packager /Users/rosssavage/Library/Developer/Xcode/DerivedData/Satimoto-evtdshsaqaokluevsdbhyvsxutjv/Build/Intermediates.noindex/Satimoto.build/DebugTestnet-iphonesimulator/Satimoto.build/Script-FD10A7F022414F080027D42C.sh (in target 'Satimoto' from project 'Satimoto')
cd /Users/rosssavage/Source/Projects/react-mobile/ios
/bin/sh -c /Users/rosssavage/Library/Developer/Xcode/DerivedData/Satimoto-evtdshsaqaokluevsdbhyvsxutjv/Build/Intermediates.noindex/Satimoto.build/DebugTestnet-iphonesimulator/Satimoto.build/Script-FD10A7F022414F080027D42C.sh
Connection to localhost port 8081 [tcp/sunproxyadmin] succeeded!
Port 8081 already in use, packager is either not running or not running correctly
Command PhaseScriptExecution failed with a nonzero exit code

Describe the solution you'd like
To be able to configure the base port settings manually either in the settings.json file or via UI
