How to Release a New Version of the Apps

You have to be part of our core dev team to do this.

Prerequirements

To enable release via fastlane, create your copy of the Appfile
```
cp fastlane/Appfile.dummy fastlane/Appfile
```
Enter values for apple_id (your Apple developer account) and itunes_connect_id (your Apple account with access to AppStoreConnect). Those two could be the same Apple account.
Sensitive files are protected with git-crypt. To compile release builds, install git-crypt:
```
brew install git-crypt
```
And unlock the encrypted files:
```
git-crypt unlock /path/to/xikolo-ios.key
```
The keyfile is managed by our core dev team and should never be made public or added to the repository.

There is a fastlane command for each step. One for all flavors and one for each flavor (suffix: _flavorname)

Retrieve the iOS Distribution Certificate (in person) and the Provisioning Profiles (via Xcode, you must be part of our development team)
Update metadata (especially the release notes) in fastlane/metadata (fastlane will create a new version in iTunesConnect)
Optional: Create app screenshots via fastlane make_screenshots
Upload metadata via fastlane upload_metadata
Optional: Upload screenshots via fastlane upload_screenschots
Upload IPA via fastlane release
Wait until iTunesConnect has processed the build
Assign the build to the release manually
Submit the release to review manually
Create a GitHub release (incl. git tag) for the release via fastlane tag_release
Refresh the dSYM files on Firebase for the current app version via fastlane refresh_dsyms
