Swift po causes error 'Failed to load linked library Metal'

Question

How can I print out a Swift variable's value in XCode 6 GM with LLDB? It seems to be broken since early betas. But at the same time po works perfectly fine in Objective-C code

I've previously tried all XCode 6 betas and got the same result. Even when I start a new project from scratch it's all the same. For example, I put a breakpoint in func application(application, didFinishLaunchingWithOptions)

(lldb) po application
error: Error in auto-import:
Failed to load linked library Metal of module sandbox - errors:
Looking for "@rpath/Metal.framework/Metal", error: not a string object

I've never imported or linked against Metal.framework in any of my projects. Does there exist any way to solve this?

Answer 1

Don't know the reason that po is broken in xCode 6, but I am able to print an object by

• Right clicking an object in the Debug Area

• and clicking -> Print Description of "OBJECT_NAME"

Hope this will help someone else, until the xCode bug is fixed

Answer 2

The bug was fixed in XCode 6.1

Resolved Issues - Debugging

Swift expressions like 'expr', 'p', and 'print' that are evaluated from the LLDB prompt in the debugger console will now work on 32-bit iOS devices. (18249931)
