Bug 201869 – Build fails as <objc/Protocol.h> header was removed from Xcode 11

• Status: RESOLVED
• Resolution: INVALID
• Component: JavaScriptCore

[Adrian Niculescu]

As seen here: https://github.com/WebKit/webkit/blob/4768b5159b9dd4b2ce126808b0da8f7bdcd67a07/Source/JavaScriptCore/API/ObjcRuntimeExtras.h#L27
The ObjcRuntimeExtras file imports <objc/Protocol.h>. This header is missing in Xcode 11 GM and GM 2.

*The header is missing when building for iOS.

Per <https://webkit.org/building-webkit/>, have you run sudo Tools/Scripts/configure-xcode-for-ios-development?

You are correct. I had multiple versions of Xcode installed and even though I ran

sudo Tools/Scripts/configure-xcode-for-ios-development

I did forget to use xcode-select to do this for every Xcode installation I needed to configure:

What I should have done:
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
sudo Tools/Scripts/configure-xcode-for-ios-development
sudo xcode-select -s /Applications/Xcode-beta.app/Contents/Developer
sudo Tools/Scripts/configure-xcode-for-ios-development

Thank you for your response.
