Issues running in Swift

[nickkjordan]

I am getting errors because my expressions are running in Swift despite the evaluateExpressionValueInFrameLanguage function

Typical error statement:

error: expected ',' separator
(int)((BOOL)((unsigned long)CFGetTypeID((CFTypeRef)(shape)) == (unsigned long)CGImageGetTypeID()))

Is there something I'm missing here? I'm just calling visualize <value>

I'm seeing something similar in my Swift project:

(lldb) caflush
error: :1:22: error: expected ',' separator
(void)[CATransaction flush]

Thanks for the reports! I will try to take a look at this soon.

Hi, I'm also seeing this error:
(lldb) pviews
error: :1:20: error: expected ',' separator
(id)[(id)[UIWindow keyWindow] recursiveDescription]

[kastiglione]

@yxztj I just tried running pviews using the "Master-Detail Application" template that comes with Xcode. I could not reproduce the error you've reported. I am using the latest Xcode GM, 6.3.2 GM. If you're able to try the GM and let me know whether the GM fixes this for you, that would be great. Or, using whichever version you have installed currently, could you try creating a new project based on the "Master-Detail Application" template and let me know if pviews is broken? Thanks!

@donshefer I just tried caflush using Xcode 6.3.2 GM, and could not reproduce the error you reported. When you update to 6.3.2, if you try caflush on your Swift project and it still fails, I would love to know and investigate more. Thanks!

@nickkjordan I am seeing different errors when I run visualize. I'll look into them. I was calling visualize on a view. Were you calling it on a image, view, or layer?

[nickkjordan]

This is bad, but I can't quite remember at this point. I think it was on a layer though, because I remember doing some animations around then

I am also getting this error.

(lldb) caflush
error: <EXPR>:1:22: error: expected ',' separator
(void)[CATransaction flush]
                     ^
                    ,

I am running the command within a swift context, and I have no idea how to change the language from swift inside the debugger. I think this is related to #74 and #68 .

Thank you for reporting this issue and appreciate your patience. We've notified the core team for an update on this issue. We're looking for a response within the next 30 days or the issue may be closed.

Seems like the problem only occurs in Swift projects in which lldb expects swift commands.

Basically, in the python scripts commands sent to the debugger using lldb.debugger.HandleCommand are all in objc. They won't work when lldb debugger is in swift mode.

[stkent]

Same issue and output as @ignat980 above. Is there an easier fix than explicitly updating all the commands sent to the debugger to use expression -l objc++?

[schwarrrtz]

Same issue and output as @ignat980 and @stkent. Similar issues with flicker.

self is of type UICollectionViewController. Ran mask and got following error.

@ultramiraculous, from what I saw in #121 you expected this ticket to be resolved as wel.
Today I still get an error when running for example mask self.view in lldb.
Got rid of my Homebrew install and using a clone from the main branch.

(lldb) mask self.view

I'm seeing the same issues. Executing show scrollView results in:
error: <EXPR>:1:19: error: expected ',' separator (void)[scrollView setHidden:0] ^ , error: <EXPR>:1:22: error: expected ',' separator (void)[CATransaction flush] ^ ,

[albertstartup]

Using show and hide work when using clone from main branch. Try cloning the latest version @tracicot
mask still produces same error as @webdevotion

[kastiglione]

I think this be closed now. Swift interop has been improved, and we can create new issues for specific issues as they arise.
