Xcode Build Numberを自動更新

この記事では、日付とカウンターに基づくカスタムフォーマットを使用して、Xcode でビルド番号をビルド毎に自動で増やす手順を説明します。下図の様にmacOS AppのAbout Menuで表示されるカッコ内の数字1がビルド番号です。

BuildNum

プロジェクトに2つファイル(versin.sh, Config.xcconfigを追加。配置場所は$SRCROOT/$PRODUCT_NAME. SRCROOTはxcodeprojディレクトリと同レベル。

#!/bin/bash
# version.sh
  # This script is designed to increment the build number consistently across all
# targets.
   
# Navigating to the 'PRODUCT_NAME' directory inside the source root that xcodeproj dirctory is placed at.
cd "$SRCROOT/$PRODUCT_NAME"
   
# Get the current date in the format "YYYYMMDD".
current_date=$(date "+%Y%m%d")
   
# Parse the 'Config.xcconfig' file to retrieve the previous build number. 
# The 'awk' command is used to find the line containing "BUILD_NUMBER"
# and the 'tr' command is used to remove any spaces.
previous_build_number=$(awk -F "=" '/BUILD_NUMBER/ {print $2}' Config.xcconfig | tr -d ' ')
   
# Extract the date part and the counter part from the previous build number.
previous_date="${previous_build_number:0:8}"
counter="${previous_build_number:8}"
   
# If the current date matches the date from the previous build number, 
# increment the counter. Otherwise, reset the counter to 1.
new_counter=$((current_date == previous_date ? counter + 1 : 1))
   
# Combine the current date and the new counter to create the new build number.
new_build_number="${current_date}${new_counter}"
   
# Use 'sed' command to replace the previous build number with the new build 
# number in the 'Config.xcconfig' file.
sed -i -e "/BUILD_NUMBER =/ s/= .*/= $new_build_number/" Config.xcconfig
   
# Remove the backup file created by 'sed' command.
rm -f Config.xcconfig-e

もう一つは

// Config.xcconfig
// Configuration settings file format documentation can be found at:
// https://help.apple.com/xcode/#/dev745c5c974
// この変数名はXcodeと衝突しなければ任意
VERSION = 1.0.1
BUILD_NUMBER = 202306211

Project Settings, Info -> Configuration & Targets Settings, Build Settings -> Versioning 図ではcarbonwatchukなるProject, TargetsのConfigurationの例を示している。

```
cd "$SRCROOT/$PRODUCT_NAME"
source version.sh
