Swift package checksum failure

[ccharp]

🐛 Describe the bug

I'm following the "Building an ExecuTorch iOS Demo App" tutorial here: https://pytorch.org/executorch/stable/demo-apps-ios.html

I try to build and test the app with the following CLI:

xcrun simctl create executorch "iPhone 15"
xcodebuild clean test \
     -project examples/demo-apps/apple_ios/ExecuTorchDemo/ExecuTorchDemo.xcodeproj \
     -scheme App \
     -destination name=executorch
xcrun simctl delete executorch

I get the following errors:

xcodebuild: error: Could not resolve package dependencies:

I have tried restarting xcode and my mac, and clearing all local caches I could think of:

rm -rf ~/Library/Developer/Xcode/DerivedData    
rm -rf ~/Library/Caches/org.swift.swiftpm 
rm -rf ~/Library/org.swift.swiftpm/configuration
rm -rf ~/Library/org.swift.swiftpm/security

Hi Corbin,

Some of the caches aren't clear still, we need to figure out which and let Xcode re-download the packages, please try to:

rm -rf ~/Library/org.swift.swiftpm

And nuke the Derived Data entirely.

You may also like to try the latest release:

git clone https://github.com/pytorch/executorch.git --branch release/0.3 --recursive && cd executorch

@shoumikhin thanks for the reply!

I had success (with a caveat) with v0.3. For some reason, my local conda environment did not install the version of numpy specified in pyprojct.toml. The following completed successfully:

./backends/apple/coreml/scripts/install_requirements.sh

./backends/apple/mps/install_requirements.sh

However, I got a runtime error related to incompatible versions of Pandas and Numpy when running

python3 -m examples.portable.scripts.export --model_name="mv3"

I had to manually install the correct version of NumPy to complete the remaining build steps:

(executorch-0.3) csc-wt@Stargazer ~/git/executorch ‹release/0.3› 
$ pip install --force-reinstall -v numpy==1.25.2

Note that pyproject.toml specifies numpy>=1.25.2.

I did not have success with v0.2.1. Same errors, though I wonder, since no one else is reproducing, if I had some stale submodule state or something. I did a clean clone for 0.3.

@ccharp that should be fixed on the main branch by https://github.com/pytorch/executorch/pull/4430
