Xcode15 compile error

That looks like a very old version. Update to the latest version of SwiftUIIntrospect (0.11.0) and let me know if it works.

Also I'd appreciate something more than a screenshot as that gives me very little contextual information about how the error is occurring.

• Is the library being linked in a project, SPM package, or are you just compiling from source?
• Are you running on Intel or M1?
• Which Xcode 15 beta are you using exactly?
• Can you provide a relevant reproducible example?

I have the same issue when installing using Cocoapods. When I install using SPM I get
Could not find module for target 'x86_64-apple-ios-simulator'... (works building on device but need simulator for SwiftUI previews)

M1
Xcode 15 Beta 6

@oscarkockum could you provide a small reproducible example that showcases this issue please? I'm unable to reproduce in my M1 machine running Xcode 15 beta 7.

Also, feel free to file a separate issue about x86_64-apple-ios-simulator with a suitable reproducible example as I wasn't able to reproduce that one in #189 either but I'd really like to get to the bottom of it once and for all.

Hi @davdroman !

I created a quick project but could not reproduce the error, and found out the issue comparing the build settings.
Had an EXCLUDED_ARCHS arm64 due to an old GoogleMaps SDK workaround. Removing it fixed the issue.

@oscarkockum that's excellent news! I'll cross post this to #189 to help folks still struggling with this.

[davdroman]

@oscarkockum just to clarify, is this particular Protocol requirement ... cannot be declared '@_spi' ... issue fixed as well, or just the x86_64-apple-ios-simulator one?

• using pod
• Intel
• Xcode 15 beta 6
• Demo.zip

xcode15 beta7 is the same error

[davdroman]

@whuxujiyuan so it seems it's this line in your Podfile that's causing the issue:

config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'

Now, I don't know exactly why that flag is set. I'd appreciate some more insight on that. But as far as the error goes, I should be able to work out a fix by adding a default conformance as suggested by the compiler.
