ci/circleci: build-and-test-swift-5.1 failure seems unrelated to the changes in this PR:

Exit status of command 'carthage bootstrap --no-use-binaries --platform iOS --cache-builds' was 1 instead of 0.
Task failed with exit code 65:

Thanks for the contribution @ejensen. Looks good, have you manually tested across other devices and not just iPhone X?
Let me look into CI.

@cocojoe Yes I verified the layout on iPhone SE, iPhone 6, iPhone 6 Plus, iPhone X, iPhone XR and iPhone XS Max.
