Xcode 5.01

There are so many warnings/errors:
First UIGraphicsBeginImageContextWithOptions not defined
Then tens of thousands context 0x0

showview self.view
Error [IRForTarget]: Call to a symbol-only function 'memset' that is not present in the target
error: warning: function 'UIGraphicsBeginImageContextWithOptions' has internal linkage but is not defined
note: used here
error: The expression could not be prepared to run in the target
Mar 11 11:37:57 shin-de-iMac.local App58ForIphone[4817] <Error>: CGContextSaveGState: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context  and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.

Thanks @btxkenshin, we'll investigate.

Related #24.

This is a bug in LLDB that happens every once in a while. The only solution that I have found is to restart Xcode/LLDB and then the issue goes away. Can you confirm that?

[btxkenshin]

@arigrant

What do you mean restart Xcode/LLDB?I tried restart Xcode many times, nothing happend.

I also had trouble by using these commands.

error: instance method 'undoManager' has incompatible result types in different translation units ('id' vs. 'NSUndoManager *')
note: instance method 'undoManager' also declared here
error: 1 errors parsing expression

Can anyone help me?

Same issue

(lldb) po _sampleView
<UIView: 0x8c2c430; frame = (96 55; 129 260); autoresize = W+H; layer = <CALayer: 0x8c2ba10>>

(lldb) showview _sampleView
error: Execution was interrupted, reason: Attempted to dereference an invalid ObjC Object or send it an unrecognized selector.
The process has been returned to the state before expression evaluation.
(lldb) 

I cannot use any "gui" related command, like mask/umask border..

I'm using xCode 5.1.1 and lldb version

~$ lldb --version
lldb-310.2.37

Hi @btxkenshin, @starFelix, @ignazioc, are the problems described here still occurring?

[kastiglione]

Closing, but please do reopen if you're seeing any of these in Xcode 6.
