One more step in order to have an Xcode project find MXParallaxHeader to be found : it needs a new tag, maybe 1.1.0 should be chosen

[Drusy]

Any plan to tag/release this @maxep ?
We now have to target the master branch to use SPM, would be nicer using a release !

[Drusy]

Spoke too fast, using the master branch results in missing headers for Swift projects
Umbrella directory '~/Library/Developer/Xcode/DerivedData/Template-fhwdlwrvaxparjdwvnikcfyarzff/SourcePackages/checkouts/MXParallaxHeader/Sources/include' not found
