Duplicate CFBundleIdentifier in copied _Testing_* overlay frameworks breaks simulator install

Lỗi nằm trong vòng lặp sao chép của copy_bundle.sh, script mà giai đoạn build của InjectionNext chạy, và trong cách khắc phục tạm thời được đề xuất là fix_testing_framework_ids.sh. Bắt đầu bằng cách chạy vòng lặp PlistBuddy trong issue trên thư mục Frameworks của iPhoneSimulator trong Xcode để xác nhận rằng _Testing_CoreTransferable.framework báo cáo định danh CoreGraphics. Hoàn thành khi bản build Debug cài được lên simulator, mọi overlay Testing* đều có CFBundleIdentifier duy nhất, và script không làm gì ngoài cấu hình Debug.

Note: includes fix

Summary

copy_bundle.sh copies every Testing*.framework from the platform developer frameworks directory into the app's Frameworks/ directory. Apple ships _Testing_CoreTransferable.framework with a copy-pasted CFBundleIdentifier that duplicates _Testing_CoreGraphics.framework's. Two frameworks sharing one identifier inside a single app bundle makes installd reject the install, so any Debug build with the InjectionNext build phase fails to launch on the simulator.

Error

Please try again later. Found bundle at
/Users/<me>/Library/Developer/CoreSimulator/Devices/<UDID>/data/Library/Caches/
com.apple.mobile.installd.staging/temp.Y6ODte/extracted/Payload/Allstar.app/
Frameworks/_Testing_CoreGraphics.framework with the same identifier
(com.apple.dt.swift-testing.overlay.CoreGraphics) as bundle at
.../Frameworks/_Testing_CoreTransferable.framework

Root cause

The identifiers as shipped by Xcode:

$ D="$(xcode-select -p)/Platforms/iPhoneSimulator.platform/Developer/Library/Frameworks"
$ for f in "$D"/_Testing_*.framework; do
    echo "$(basename $f): $(/usr/libexec/PlistBuddy -c 'Print :CFBundleIdentifier' "$f/Info.plist")"
  done

_Testing_CoreGraphics.framework:      com.apple.dt.swift-testing.overlay.CoreGraphics
_Testing_CoreImage.framework:         com.apple.dt.swift-testing.overlay.CoreImage
_Testing_CoreTransferable.framework:  com.apple.dt.swift-testing.overlay.CoreGraphics   ← wrong
_Testing_Foundation.framework:        com.apple.dt.swift-testing.overlay.Foundation
_Testing_UIKit.framework:             com.apple.dt.swift-testing.overlay.UIKit

This is an Apple bug in the toolchain, but InjectionNext is what surfaces it: nothing else copies these overlays into a shipping app bundle. The relevant loop in copy_bundle.sh:

(cd "$PRODUCTS_DIR" && for fwork in $TESTING_FRAMEWORKS \
    "$PLATFORM_DEVELOPER_LIBRARY_DIR"/Frameworks
    TESTING_COPIED="$CODESIGNING_FOLDER_PATH/Frameworks/$(basename "$fwork")"
    if [ -f "$fwork/Info.plist" -a ! -d "$TESTIN
        rsync -a "$fwork" "$CODESIGNING_FOLDER_PATH/Frameworks" &&
        codesign -f --sign "$EXPANDED_CODE_SIGN_
            --preserve-metadata=identifier,entitlements,flags ... "$TESTING_COPIED"
    fi
done)

Note --preserve-metadata=identifier — the bad identifier is carried through to the signature as well.

Reproduce

1. Add the standard InjectionNext run-script phase to an iOS app target.
2. Build & run in Debug on a simulator with an Xansferable.framework carries the CoreGraphicsidentifier.
3. Install fails with the error above. Allstar.ath overlays with identical CFBundleIdentifiers.

Suggested fix (upstream)

Derive each overlay's identifier from its own fr, and stop preserving identifier when re-signing:

(cd "$PRODUCTS_DIR" && for fwork in $TESTING_FRA
    "$PLATFORM_DEVELOPER_LIBRARY_DIR"/Frameworks/_Testing_*.framework; do
    TESTING_COPIED="$CODESIGNING_FOLDER_PATH/Fra")"
    if [ -f "$fwork/Info.plist" -a ! -d "$TESTING_COPIED" ]; then
        rsync -a "$fwork" "$CODESIGNING_FOLDER_P
        # Xcode ships _Testing_CoreTransferable with CoreGraphics' identifier;
        # installd rejects two bundles sharing a
        OVERLAY="$(basename "$fwork" .framework)" &&
        /usr/libexec/PlistBuddy -c \
            "Set :CFBundleIdentifier com.apple.dt.swift-testing.overlay.${OVERLAY#_Testing_}" \
            "$TESTING_COPIED/Info.plist" &&
        codesign -f --sign "$EXPANDED_CODE_SIGN_IDENTITY" --timestamp=none \
            --preserve-metadata=entitlements,fla
            --generate-entitlement-der "$TESTING_COPIED"
    fi
done)

Rewriting all overlays (rather than special-casing CoreTransferable) keeps the script correct if Apple duplicates another
identifier later.

Workaround (verified working)

For anyone hitting this before an upstream fix lld phase after the InjectionNext phase thatrepairs the copied overlays in place.

BuildScripts/fix_testing_framework_ids.sh:

#!/bin/bash
#
# Apple ships _Testing_CoreTransferable.framework with the same CFBundleIdentifier as
# _Testing_CoreGraphics.framework (com.apple.dt.Graphics).
# InjectionNext's copy_bundle.sh copies every _Testing_* overlay into the app, and
# installd refuses to install a bundle containinidentifier.
#
# Rewrite each copied overlay's identifier to ma, then re-sign.
# Must run after the InjectionNext build phase.

[[ "$CONFIGURATION" =~ Debug ]] || exit 0

FRAMEWORKS="$CODESIGNING_FOLDER_PATH/Frameworks"
[ -d "$FRAMEWORKS" ] || exit 0

shopt -s nullglob
for fwork in "$FRAMEWORKS"/_Testing_*.framework; do
    plist="$fwork/Info.plist"
    [ -f "$plist" ] || continue

    name="$(basename "$fwork" .framework)"
    want="com.apple.dt.swift-testing.overlay.${n
    have="$(/usr/libexec/PlistBuddy -c 'Print :CFBundleIdentifier' "$plist" 2>/dev/null)"
    [ "$have" == "$want" ] && continue

    echo "fixing $name: $have -> $want"
    /usr/libexec/PlistBuddy -c "Set :CFBundleIdentifier $want" "$plist" &&
    codesign -f --sign "${EXPANDED_CODE_SIGN_IDEe \
        --preserve-metadata=entitlements,flags --generate-entitlement-der "$fwork"
done

Then chmod +x it and add a New Run Script Phase last (after InjectionNext):

"${SRCROOT}/BuildScripts/fix_testing_framework_i

It's idempotent, no-ops outside Debug, and --prey drops identifier so the new one makes it intothe signature.
