Application architecture

External assets

A number of assets used in the app come from other repositories, and should be periodically updated. Because updating these items can be a lengthy process it is performed manually rather than at build time:

• iD presets database (https://github.com/openstreetmap/id-tagging-schema)
• iD presets icons (https://github.com/ideditor/temaki, https://github.com/mapbox/maki)
• Name Suggestion Index (https://github.com/osmlab/name-suggestion-index)
• NSI brand imagery (pulled from Facebook/Twitter/Wikipedia)
• StreetComplete quest filters (https://github.com/streetcomplete/StreetComplete)
• WebLate translations (https://hosted.weblate.org/projects/go-map/app)

How to update external assets

Starting from the src directory:

• (cd presets && ./update.sh) # fetches latest presets.json, etc. files and NSI
• (cd presets && ./getBrandIcons.py) # downloads images from various websites and converts them to png as necessary
• (cd presets && ./uploadBrandIcons.sh) # uploads imagery to gomaposm.com where they can be downloaded on demand at runtime (password required)
• (cd POI-Icons && ./update.sh) # fetches maki/temaki icons
• (cd xliff && ./update.sh) # downloads latest translations from weblate (password required). This step is very noisy and produces many pages of warnings that can be ignored.

Continuous integration

Prerequisite

• Make sure you have fastlane installed. (From a terminal, change to the src/iOS directory and run bundle install.)
• Since fastlane stores your provisioning profiles and certificates in a Git repository (MATCH_REPO), you need to create a new, empty repository if you haven't already. The profiles and certificates are protected by a password (MATCH_PASSWORD).
• When creating the Beta locally, fastlane will make sure that your certificates and provisioning profiles are up-to-date.

How to release a Beta locally

You'll need to obtain the values for the following parameter:

• MATCH_REPO: The URL to the Git repository that contains the provisioning profiles/certificates
• MATCH_PASSWORD: The password for encrypting/decrypting the provisioning profiles/certificates
• FASTLANE_TEAM_ID: The ID of the developer team at developer.apple.com
• FASTLANE_USER: The email address that is used to # to App Store Connect
• FASTLANE_ITC_TEAM_ID: The ID of the team at appstoreconnect.apple.com

In order to release a new Beta to the TestFlight testers, run

% MATCH_REPO=<GIT_REPOSITORY_URL> \
  MATCH_PASSWORD=<MATCH_PASSWORD> \
  FASTLANE_TEAM_ID=<APPLE_DEVELOPER_TEAM_ID> \
  FASTLANE_USER=<APP_STORE_CONNECT_EMAIL> \
  FASTLANE_ITC_TEAM_ID=<APP_STORE_CONNECT_TEAM_ID> \
  bundle exec fastlane beta

Formatting

In order to have a consistent code style, please make sure to install SwiftFormat and run it on a regular basis. Consider setting up a pre-commit Git hook, as described here.

Assets

The Go Map!! app icon was created by @Binnette.

Presets and translation

Go Map!! is using iD presets, so you can improve translations by improving translations of iD presets.
