Tests

• all tests were successful
• prepare updates to LoopDocs and LGTM

Test Details

Build with Mac-Xcode, both Xcode 16.4 and Xcode 26.1.1

• build succeeded and app behavior is nominal
• Because this PR changes the build order, if you are using an existing clone, you must at least do a clean build folder and you might need to rm -rf ~/Library/Developer/Xcode/DerivedData before you can build successfully

Build using GitHub actions (which uses Xcode 16.4).

• successful build: https://github.com/docs-test/LoopWorkspace/actions/runs/19584158137

Install that build onto a test phone (SE 2nd gen running iOS 18.7.2)

• App installs with correct branch and version number
• behavior is nominal

Build using Mac-Xcode with a fresh download:

/bin/bash -c "$(curl -fsSL \
  https://raw.githubusercontent.com/loopandlearn/lnl-scripts/main/BuildLoop.sh)" \
   - update_dev_to_3.9.3

Apply typical customizations

• no changes are required to the customization select script, however, live_activity will be part of dev once this PR is merged so will need to be removed from the customization list if present
