As of #85052 the Flutter engine iOS artifacts contain iOS ARM simulator binaries, and the Flutter.xcframework should only contain a ios-arm64_x86_64-simulator directory. It also was built on Xcode 12, so the ios-armv7_arm64 directory has been renamed ios-arm64_armv7. However, because the artifact downloads do not remove old directories from the bundle, the old and new architecture triple directories exist next to each other.

Steps to reproduce

$ git checkout stable
$ flutter precache
$ git checkout a2fa6d4 # master as of https://github.com/flutter/flutter/pull/85052
$ flutter precache
$ ls bin/cache/artifacts/engine/ios/Flutter.xcframework

Expected

ios-arm64_armv7
ios-arm64_x86_64-simulator

Actual

ios-arm64_armv7
ios-arm64_x86_64-simulator
ios-armv7_arm64
ios-x86_64-simulator
