A simple Bash script to generate an average build time for your iOS project. Replace with your project's workspace and scheme before use.

averageBuildTime.sh

#!/bin/bash

# Workspace and scheme parameters for the project
workspace="ProjectWorkspace.xcworkspace" # TODO: Replace with your project's workspace
scheme="ProjectScheme" # TODO: Replace with your project's scheme

# The number of times to build the project
numRuns=3

# Abort the process if any of the commands in this script fail
set -e

# Variable to hold the total build duration over all runs
totalBuildTime=0

echo "Building project $numRuns times..."

# Perform the build n times
for ((i=1;i<=numRuns;i++))
do
  echo "Starting build $i..."

  # Clean the project first
  echo "Cleaning project before starting the build..."
  xcodebuild \
  -workspace "$workspace" \
  -scheme "$scheme" \
  clean
  echo "Clean complete."

  # Get the start time of the build
  start=`date +%s`
  echo "Starting build $i at $start..."

  # Build the project
  xcodebuild \
  -workspace "$workspace" \
  -scheme "$scheme" \

  # Get the end time of the build
  end=`date +%s`
  echo "Build $i ended at $end."

  # Calculate the time it took to build the project
  runtime=$((end-start))
  echo "Build $i took $runtime seconds."

  totalBuildTime=$((totalBuildTime+runtime))
done

# Calculate the average build time
averageBuildTime=$((totalBuildTime/numRuns))
echo "Average build time was $averageBuildTime seconds."
