iOS11 AppIcon can't change

Question

• Xcode 9 beta 6

• iOS 11 beta 10

  I want package application with custom App icon , so I try to replace AppIcon.png files at DerivedData (/Users/XXX/Library/Developer/Xcode/DerivedData/project/Build/Products/Debug-iphoneos/xxx.app)

  It worked at iOS 10, but doesn't work at iOS 11

  Can anybody solve it?

  Thanks for advance

I have found a solution. I change app icons in the source .xcasset folder, not in Derived Data (using ImageMagick). So, here is my script:

#!/bin/bash

IFS=$'\n'
BASE_ICONS_DIR=$(find ${SRCROOT}/${PRODUCT_NAME} -name "AppIcon.appiconset")
IFS=$' '
CONTENTS_JSON="${BASE_ICONS_DIR}/Contents.json"

version=`/usr/libexec/PlistBuddy -c "Print CFBundleShortVersionString" "${INFOPLIST_FILE}"`
# The next line adds special suffix, necessary in my project
version="${version/'$(VERSION_SUFFIX)'/$VERSION_SUFFIX}"

function tag() {
    export PATH=$PATH:/usr/local/bin:/opt/boxen/homebrew/bin/
    ICON_PATH=$1

    width=`identify -format %w ${ICON_PATH}`
    [ $? -eq 0 ] || exit 1

    height=$((width * 30 / 100))

    if [ "${CONFIGURATION}" != "AppStore" ]; then
       convert -background '#0008' \
       -fill white -gravity center \
       -size ${width}x${height} \
       caption:"${version}" \
       "${ICON_PATH}" +swap -gravity south -composite "${ICON_PATH}" || exit 1
    fi
}

ICONS=(`grep 'filename' "${CONTENTS_JSON}" | cut -f2 -d: | tr -d ',' | tr -d '\n' | tr -d '"'`)

ICONS_COUNT=${#ICONS[*]}

IFS=$'\n'

for (( i=0; i<ICONS_COUNT; i++ )); do
    tag "$BASE_ICONS_DIR/${ICONS[$i]}"
done

This script is executed before Copy Bundle Resources. After executing app icons are changed, so I need to revert changes with additional Run Script as a last Build Phase:

if [ "${CONFIGURATION}" != "AppStore" ]; then
   IFS=$'\n'
   git checkout -- `find "${SRCROOT}/${PRODUCT_NAME}" -name AppIcon.appiconset -type d`
fi

My Build Phases looks like this:
