问题:

iOS applications built with Xcode 6 or higher allow embedding dynamic iOS frameworks within them. I am building a shared framework and would like to embed a sub-framework. How can I accomplish this?

Note: This is possible and is being used in production (for e.g., with Swift frameworks in CocoaPods).

Found the answer. Here's how it's done:

Navigate to Target > Build Phases
Click the small "+" icon and select "New Run Script Build Phase"

Paste the following:

cd $BUILT_PRODUCTS_DIR

mkdir $PROJECT_NAME.framework/Frameworks &>/dev/null

for framework in *.framework; do
    if [ $framework != $PROJECT_NAME.framework ]; then
        cp -r $framework $PROJECT_NAME.framework/Frameworks/ &>/dev/null
    fi
done

@Vatsal Manot's answer was very helpful for me. I modified it a bit and also had a need to sign the copied embedded framework. My script is below.

cd $BUILT_PRODUCTS_DIR/$PRODUCT_NAME.app/Frameworks/Custom.framework/Frameworks
for framework in *.framework; do
    mv $framework $BUILT_PRODUCTS_DIR/$PRODUCT_NAME.app/Frameworks/
    /usr/bin/codesign --force --sign "iPhone Developer" --preserve-metadata=identifier,entitlements --timestamp=none $BUILT_PRODUCTS_DIR/$PRODUCT_NAME.app/Frameworks/$framework
done
