Fix that explicitly weak links XCTAutomationSupport is coming :)

Wow, did they remove XCElementSnapshot? Or maybe just moved to different framework. Interesting.

marekcirkos on 23 Jul 2018

From what I can see it's still in XCTAutomationSupport framework. It happened with XCDeviceEvent when Xcode 9 came out, even though it's still in the framework as well.

An ugly workaround can be just to ignore it in linking time (tested) by adding the following to the linker flags:
-Wl,-U,"_OBJC_CLASS_$_XCElementSnapshot"

Not bitcode compatible, ugly, but it works.

yep, I can observe it in XCTest headers dump, that XCElementSnapshot class is still used, however is not exposed anywhere. Only some extensions of it are visible though

Still relevant for Beta 5.

Dan-Maor on 31 Jul 2018

@Dan-Maor where I could add above flags? I try to add to Other Linker Flags (target: WebDriveAgentLib) but it throws the same error as above.
I'm using Xcode 10 beta5.

@marekcirkos Any progress? Thanks

@rjaros87
Technically it's a single entry, make sure to copy it as it is (with the commas).
Also - try cleaning the project first.

Oops, that's what I thought I've written, Github changed the first '_' to italic. Fixed.

@rjaros87 go to File->Project Setting，change the build system to Legacy Build System. Then add to Other Linker Flags...
