iOS app missing dependencies //build/toolchain/ios:ios_x64

[rollyceballos]

Problem

I've cloned the repo, setup ninja, gn, openssl and pkg-info but still stuck with Xcode not finishing the chip_xcode_build_connector.sh script

I'm getting an Error Unresolved dependencies looking for //build/toolchain/ios:ios_x64 and can't figure out what that is. I've seen various issues reported with the iOS project but all other workarounds/solutions doesn't work so maybe this is a recent bug or I completely missed a step in the CHIP setup guide?

Proposed Solution

Add missing setup guide if any?

I figured this one out as actually running the app on an iPhone instead of just building it against a simulator. I should have figured as this was more of device integration I should have thought of it this way. It may help if there's a mention in any of the documents to run the iOS app against an actual device or build it to an arm64 target instead of the simulator so it's quick for anyone starting on this project.
