How to add a framework inside another framework (Umbrella Framework)

Question

I have build a framework using the following tutorial.

And I also got this framework.

I am trying to implement the second Framework inside mine, from what I re

Answer 1

HERE IS AN DEMO PROJECT:

Umbrella Framework Demo

All answers under this line are wrong, cause they just do the thing that manually copy sub frameworks into "umbrella framework"

How to add a framework inside another framework (Umbrella Framework)

Umbrella framework

First thing we should know that "umbrella framework" is a conception in Mac OS not in iOS, the official document is here

https://developer.apple.com/library/content/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/CreationGuidelines.html#//apple_ref/doc/uid/20002254-BAJHGGGA

if you want to create an un-recommend "UmbrellaFramework", you must do these process step by step, and know details during the compile and link periods

1. Change all sub frameworks Mach-O to Static Library, it means compile this target as Static Library(.a)
2. Manually copy all sub-Framework into UmbrellaFramework during the build phase(Like other answers did)
3. Add "FakeBundleShellScript" to Target "UmbrellaFramework", it makes all sub frameworks package itself resources as bundle to join "UmbrellaFramework"
4. Change the framework load function, you must load the sub-framework resources via path or url, cause it became an bundle, this step means you should have the supreme control of all codes both sub-frameworks & umbrella

!!Here is an example of "FakeBundleShellScript" you can refer

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
BUNDLE_IN_ROOT="$APP_PATH/${FRAMEWORK_EXECUTABLE_NAME}.bundle"
if [[ -e "$FRAMEWORK_EXECUTABLE_PATH" ]]; then
  FRAMEWORK_MACH_O="$(otool -a "$FRAMEWORK_EXECUTABLE_PATH" | head -n 1)"
  FRAMEWORK_FAT_ARCH="$(lipo -info "$FRAMEWORK_EXECUTABLE_PATH")"
else
  FRAMEWORK_MACH_O="NO EXIST"
  FRAMEWORK_FAT_ARCH="NO EXIST"
fi
echo "FRAMEWORK_EXECUTABLE_NAME is $FRAMEWORK_EXECUTABLE_NAME"
echo "FRAMEWORK_EXECUTABLE_PATH is $FRAMEWORK_EXECUTABLE_PATH"
echo "FRAMEWORK_MACH_O is $FRAMEWORK_MACH_O"
echo "FRAMEWORK_FAT_ARCH is $FRAMEWORK_FAT_ARCH"
echo "BUNDLE_IN_ROOT is $BUNDLE_IN_ROOT"
if [[ "$FRAMEWORK_MACH_O" =~ "Archive :" ]]; then
  echo "Rmove Static-Mach-O is $FRAMEWORK_EXECUTABLE_PATH"
  rm "$FRAMEWORK_EXECUTABLE_PATH"
  defaults write "$FRAMEWORK/Info.plist" CFBundlePackageType "BNDL"
  defaults delete "$FRAMEWORK/Info.plist" CFBundleExecutable
  if [[ -d "$BUNDLE_IN_ROOT" ]]; then
    rm -rf "$BUNDLE_IN_ROOT"
  fi
  mv -f "$FRAMEWORK" "$BUNDLE_IN_ROOT"
elif [[ "$FRAMEWORK_FAT_ARCH" =~ "Architectures in the fat file" ]]; then
  #statements
  EXTRACTED_ARCHS=()
  for ARCH in $ARCHS
  do
    echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
    lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
    EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
  done
  echo "Merging extracted architectures: ${ARCHS}"
  lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
  rm "${EXTRACTED_ARCHS[@]}"
  echo "Replacing original executable with thinned version"
  rm "$FRAMEWORK_EXECUTABLE_PATH"
  mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"
fi
done

As all I said, the key point of to make an un-recommend "UmbrellaFramework" is !!!! [Compile the sub-frameworks as Static, process the resources via fake a bundle], REMEMBER!! Apple always said DONT'T CREATE AN UmbrellaFramework

if you can understand Chinese, more details to make an "UmbrellaFramework" can be obtained from my blog
