Version Settings Bundle

AppVersionBundle.md

This Gist explains how to set up an Xcode proj to show the app version and the last six characters of the lastest git commit message.

1. Add contents of SettingsAccess.swift to the Xcode project.
2. Add a Settings bundle to the app, then configure Root.plist like displayed here.
3. Add a Run Script build phase to the Xcode project. Copy the contents of CommitHash.sh to phase.

CommitHash.sh

#!/bin/bash
set -o errexit
set -o nounset

INFO_PLIST="${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/Info"
COMMIT_HASH=$(git rev-parse HEAD)

defaults write "$INFO_PLIST" CommitHash $COMMIT_HASH

Root.plist

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

SettingsAccess.swift

import Foundation

struct SettingsAccess {
    fileprivate static let appVersionKey = "app_version"
    
    static func initialize() {
        
        if let shortVersion = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as? String, let version = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") as? String, let commit = Bundle.main.object(forInfoDictionaryKey: "CommitHash") as? String {
            let trimmedCommit = commit[commit.index(commit.endIndex, offsetBy: -6)...]
			
            UserDefaults.standard.set("\(shortVersion)(\(version)) \(trimmedCommit)", forKey: appVersionKey)
        }
    }
}
