AudioKit Cookbook v.5 build fails (xcode 13.2.1)

Question

I have been trying to build, to no avail, the Cookbook under Xcode 13.2.1. I get "Analyze Failed" with the following errors:

Stk:

Command CompileSwiftSources failed with a nonzero exit code

Semantic issues (20): (some of the error messages appear with varying array sizes, I quote only one for brevity):

• No template named num_get (istream)
• No template named bitset (istream)
• Implicit instantiation of undefined template std::ostream (sstream, istream)
• Invalid operands to binary expression ('std::ostringstream' (aka 'basic_ostringstream') and 'const char [60]') (instrmnt.h, Filter.h, Whistle.cpp)
• Invalid operands to binary expression ('std::ostream' (aka 'basic_ostream') and 'char') (Stk.h)

AudioKit: Command CompileSwiftSources failed with a nonzero exit code

Any suggestions to get this going? I am at a complete loss. I am targeting iOS 15. I'll be happy to provide additional information, if needed.

For reference here are the versions of the Cookbook and dependencies that I'm using:

• Cookbook (?, 5/2/2022 commit)
• AudioKit 5.4.1
• AudioKitEx 5.4.0
• AudioKitUI (?, 5/3/22 commit)
• DunneAudioKit 5.4.1
• KissFFT 1.0.0
• SoundpipeAudioKit 4.4.1
• SporthAudioKIt 5.3.1
• STKAudioKit 5.3.0

Answer 1

Does it look like all the Swift Packages were loaded properly? I'm on that same Xcode version so it should be working. Here are a few things to try:

• Select File > Packages > Resolve Package Version

• Delete the app from your device/simulator if you ran it previously on another Cookbook version

• Restart Xcode and select Product > Clean Build Folder

A fresh install of Xcode did the trick. Go figure. Thanks everyone for your suggestions and information.

Answer 3

For me this happened the second time. I was working on a pure C++ command line project in Xcode 14.1 and suddenly couldn't build it anymore. I couldn't build anything if it had #include <iostream> line.

Reinstalling Xcode fixed this problem. Thanks for the tip! Here is what I did eventually:

• Deleted Xcode 14.1 from /Applications
• Deleted /Library/Developer/CommandLineTools
• Deleted ~/Library/Developer/Xcode/DerivedData/
• Rebooted
• Reinstalled Xcode from .xip archive and reinstalled CommandLineTools for Xcode 14.1 from .pkg
