building to simulator - ld: symbol(s) not found for architecture x86_64

[8secz-johndpope]

arm64 Undefined symbols for architecture x86_64: "_OBJCCLASS$_ARView", referenced from: objc-class-ref in ARViewController.o (maybe you meant: _OBJCCLASS$_ARViewController) ld: symbol(s) not found for architecture x86_64

I ripped out the production sdk and threw in the simulator sdk

I'm not clear how to use together - sometimes I need to build to device right now I need to build to simulator for other things...

are there some settings to check? above it seems embed frameworks uses sim folder link with uses the link library....

same problem -

ld: warning: ignoring file /Users/matt/Documents/gitWorkspace/8secondz-ios/8secondz/External/DeepAR.framework/DeepAR, building for iOS Simulator-x86_64 but attempting to link with file built for iOS-arm64 Undefined symbols for architecture x86_64:

I'm sure it's possible to combine the two frameworks together - not sure how though. If not - it's fine I can work around it - instructions aren't clear though.

It seems that the two frameworks included ( one for hardware / one for simulator ) can not / or should not be both imported - ie - if you're building to simulator - use simulator framework / if your building to device rip out simulator and use device framework - which is what I mostly use so not a problem - but need to test something with ios13.

so dropping in the simulator frameworks works a treat for dev / both on device + simulator - but not appropriate for app store. can get around it by creating a new schema target. developement prod

distantly related - (actually didn't work so well) https://gist.github.com/kenthumphries/cf04683184217c7331f9c213c556c65a https://stackoverflow.com/questions/40400086/xcode-add-embedded-binary-with-buildscript/40484337#40484337

this code successfully signs and includes only for debug builds / framework is weakly linked - it's an awesome pod - worth having a look. https://raw.githubusercontent.com/CocoaDebug/CocoaDebug/master/CocoaDebug/copy_and_codesign.sh

basically - the answer to this problem don't include both frameworks / make them weakly linked - then at run time - in build script - determine what to include copy and codesign. I'll take another look when I have more bandwidth.

I believe I went through a few steps in the right direction but even though I managed to select the right frameworks between simulator and production I still have the error

If you need simulator and production SDKs in the same project you could create two separate targets for them.

Then you can add the frameworks only to the target that uses them and set up embedding as needed.
