Re: Problem loading a CoreDataModel from a Static library in Swift

[Sixten Otto]

You might want to include some of your code for loading the model, to make
this discussion less hypothetical.

Also, when you say that "ObjC works just fine", what does that mean?
Objective-C code in the same app that's trying to load the same model that
Swift code in that app can't load? Or some separate test written in
Objective-C?

Custom font for UIAlertAction

[Eric E. Dolecki]

I am hoping to change the font for the buttons in a UIAlertController (not
the color, just the face as the styles give me what I want). It doesn’t
appear I can use an attributedString (takes String) - is there any action I
can take to achieve this besides subclassing?

Re: Problem loading a CoreDataModel from a Static library in Swift

[Jim Adams]

What I mean is that if I create an App using ObjC and include my library and 
bundle there is no error message. This message only happens with Swift based 
apps. Apparently The Google Maps SDK had the same issue but their resolution 
was sketchy.

Re: Custom font for UIAlertAction

[Wojciech Czekalski]

Yes, you can recursively iterate through the alert view's subviews and check 
for a UILabel and set the font on it. It's hacky but I don't think there's 
another way

Do NOT do things like this. The view hierarchy is considered private and the 
results of any changes you make are not guaranteed to continue working into the 
future.

Re: Custom font for UIAlertAction

[Wojciech Czekalski]

I dont recommend it either but it is possible to do it this way. It requires 
extensive testing etc. If done properly however won't crash your app if 
anything but will silently fail.

What I’m saying is that UIKit won’t guarantee that this won’t someday crash 
your application. Doing things like this is wholly undefined, do not do them.

Re: Custom font for UIAlertAction

[Doug Hill]

I will echo the sentiments NOT to poke around into view hierarchies which 
aren’t public parts of the interface. It might work now but you will lose in 
the long run when Apple changes something, which they will.

I suggest looking into using Appearance proxies. You can change just about any 
style/appearance of UI controls, either app-wide or when controls are contained 
in a specific view controller. I’ve done this for many UIKit views/controllers 
with great results, particularly when there isn’t a public interface to modify 
their style.

Re: Custom font for UIAlertAction

It would appear that the UIAlertController (UIAlertAction) does not conform
to appearance proxies. Here is a list of controls that do (up to iOS 8.0)

Re: Custom font for UIAlertAction

[Doug Hill]

What I do is use the Appearance proxies to customize the button, not the 
UIAlertController. For example, use the Appearance proxy to set font of a 
button when contained in a UIAlertController.

Re: Custom font for UIAlertAction

[Eric E. Dolecki]

So you’re talking about iterating through the subviews to find the
UIButton. Which most feel is not the most prudent way to tackle this. If I
had direct access to buttons, I could just set the font for them and not
bother with appearance proxy.

Either I’ll live with the way the alerts look now and file with Apple for
an enhancement, or just roll up my own alert class that looks exactly how I
want - which shouldn’t be very difficult. In fact, after spending the time
in searching and trying various things I could have probably rolled it all
up and have been on to the next thing.

Re: Custom font for UIAlertAction

[Doug Hill]

Instead of changing a single instance, the appearance proxies change the style 
for all instances of a control. So, calling:

[[UIButton appearance] setTitleColor:newColor]

would change the title color for all buttons in your app. I’m going to leave as 
an exercise to the reader how to change the title font for all buttons. You can 
also make these changes only when the control is contained in a view 
controller. Again, I’ll leave how to do this as an exercise to the reader.

CGContextClipToRects: invalid context 0x0.

[Richard Charles]

I am trying to debug the following error.

: CGContextClipToRects: 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.

I have added a symbolic breakpoint on CGPostError. The application halts 
completely with Apple’s frameworks. There is not a single stack frame from my 
code except main.

The first few stack frames look like this.

#0  0x7fff8e5686c7 in CGPostError ()
#1  0x7fff8e568798 in handle_invalid_context ()
#2  0x7fff8d5ad2c0 in -[NSView _drawRect:clip:] ()

The first thing I noticed is that there are no debug symbols in Apple’s 
frameworks. It that normal?

If there were debug symbols present I could query the NSView object to see what 
class it is to see how it relates to my code.

How do you debug something with no symbols?

Environment woes executing scripts from my OS X app

[Rick Mann]

I'm working on an OS X app that unfortunately has to call a series of bash and 
python scripts for part of the processing it does. I was able to include the 
scripts in my app's bundle, and invoke them there, but the environment is 
different when launched via my app than when launched on the command line. How 
can I best control the environment used when executing external scripts?
