How to make a release

Apple

test the build on a real device. It is imperative that you run selftest and it gives you OK
if necessary, up version number in all relevant files (you can use ./edit-version-number.sh)
run ./scripts/release-notes.sh - it prints changelog between latest tag and now, put this output under new version in file ios/fastlane/metadata/en-US/release_notes.txt (on top); if file got too big delete the oldest version from the bottom of the file
now is a good time to commit a ver bump and release notes changes
create this release version in App Store Connect (iTunes) and attach appropriate build. note last 4 digits of the build and announce it - this is now a RC. no need to fill release notes yet
cd ios/ and then run DELIVER_USERNAME="my_itunes_email@example.com" DELIVER_PASSWORD="my_itunes_password" fastlane deliver --force --skip_binary_upload --skip_screenshots --ignore_language_directory_validation -a org.doichain.doiwallet --app_version "6.6.6" but replace 6.6.6 with your version number - this will upload release notes to all locales in itunes
go back to App Store Connect and press Submit for Review. choose Yes, we use identifiers - for installs tracking
once its approved and released it is safe to cut a release tag: run git tag -m "REL v6.6.6: 76ed479" v6.6.6 where 76ed479 is a latest commit in this version. replace the version as well. then run git push origin --tags
you are awesome!

do android after ios usually
test the build on a real device. We hace accounts with browserstack where you can do so.
its imperative that you run selftest and it gives you OK. note which build you are testing
go to appcenter.ms, find this exact build under master builds, and press Distribute -> Store -> Production. in Release notes write the release, this field is to smaller than iOS, so you need to keep it bellow 500 characters.
now just wait till appcenter displays a message that it is succesfully distributed
noice!
