I have an Xcode project I've been working on for months. I've never had a problem with NSLog, but after upgrading to Xcode 4.2 nothing will log to the console. I even tried throwing this in viewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(#"Can anyone hear me?");
And nothing. Is anyone else having this problem or know a solution?
Well, this is embarrassing. The console got deactivated somehow and I was actually watching the variables window. Pressing Shift + + C did the trick.
Many thanks to Robert King on this thread:

This is a bug of Xcode8 + iOS10, we can solve it in this way:
When on simulator, add the Name OS_ACTIVITY_MODE and the Value
Variables disable and check it (Product -> Scheme -> Edit Scheme -> Run -> Arguments -> Environment).
When on device, only add OS_ACTIVITY_MODE and check it（don't add the Value). You'll see the NSLog in the Xcode8 Console.
In iOS10, a lot of system logging is displayed on the console. This can be disabled by including the OS_ACTIVITY_MODE = disabled in the Run Arguments for your scheme
However for iOS10, NSLog messages will not be displayed anymore.
In lower iOS versions the messages will still be displayed. So maybe for most test cases you can use a lower iOS version.
Otherwise you can include a Swift function which prints (print function) your text, this is working okay in iOS10.
Tested on iOS10.0.2 and iOS9.3
My issue is that I have Debugger Output selected. Once I changed it to either All output or target output NSLogs appear fine.
In case this confuses you its on the left of the Debug area.
I had the same issue.
The trick is to search and remove the below mentioned line from the project.
#define NSLog(...)
Search the entire project and remove it.
I just experienced this, so here's another thing to check.
-> Make sure you don't have anything typed in the Filter field below the Log Output. So, in my case I was searching for a term in the logger and forgot to delete the searched terms out of the Filter text field. DOH!
My issue was that I'd accidentally severed the referencing outlet from App Delegate (delegate - file's owner).

I am using CCS to program a MSPFR6989 and I’ve debugged and the code is working but I can’t get variables or registers to come up. It remains blank. enter image description here
use double click onto your variables and choose watch expression. You can find your variables under expression from now. If it shows you its name but a red error message try step by step debugging, works for me everytime.
I am in the Edit Command mode Shortcuts dialog and things seem reasonable ..
But the actual behavior is a different story
When using the Option modifier (plus a non-modifier key) it just ends up printing a high-ascii character value in the add shortcut area .. and then when I refresh the page it has gone away.
I can not get Command modifier (plus a non-modifier key) to work at all. It is jus ignored.
The Control modifier (plus any key) is completely ignored.
So there is a basic usability misunderstanding here. Advice appreciated.
I added 'Ctrl-Q' as a shortcut to restart kernel and run all the cells. You can see the picture below. It is working fine. In the 'Ctrl-Q', 'Q' was just lowercase and it ran successfully.
Tokenize2 is a javacsript lib to select multiple options.
It provides a very neat UI to start writing and then get a list of options to select from. Selected options will show up as "tags" that can be removed with "x" link.
So far all is fine. But Right now you need to know what your looking for and start write at least one character to see matching alternatives.
In my scenario there are very few alternatives and they are not known to the user. I would like to show ALL options when the user clicks the input box. There is a configuration option named searchMinLength but it is already set to 0.
Is there a workaround that can be used? Maybe like triggering load and dropdown manually?
I know there are a lot of similar alternatives but I picked Tokenize2 because:
It looks clean and nice
It works in mobile browsers
I don't know if there is an "official" approach, but after some investigation I have found an acceptable workaround.
After downloading the Tokenizer2 sourceode I found the following line that triggered my attention:
if(this.input.val().length > 0){
this.trigger('tokenize:search', [this.input.val()]);
}
My interpretation is that the internal search command is not triggered unless the user input has at least one character. This line in sourcecode could easily be modified. I have filed a suggestion for this here: https://github.com/zellerda/Tokenize2/issues/26
My current workaround is to add an event listener for the select event and there trigger the internal search command. That works fine for my scenario and does not force a source code rewrite.
$("#my-dropdown").on("tokenize:select", function (e: Event, routedEvent: boolean) {
$("#my-dropdown").trigger('tokenize:search', "");
});
Tokenize2
This link worked for me GitHub
$('.tokenize-sample-demo1').on('tokenize:select', function(container){
$(this).tokenize2().trigger('tokenize:search', [$(this).tokenize2().input.val()]);
});
I just upgraded to Xcode 7 and I can no long use the NSLog statement to show messages for debugging? NSLog(#"I am at the start of the loop"); This used to work and now I can't even write the statement in the code, it gives me a "expected parameter declarator"? What am I missing? I researched this and can't find anything saying it's changed. One day it worked and now it doesn't. I can find it in my older projects and it still works within those older projects. Any help would be appreciated.
Try Shift + + C (equivalent to View > Debug Area > Activate Console)

I want to delete this red-marked target, but am unable to.
The "minus" button in the dialogue remains greyed-out, it doesn't respond to backspace or delete keys and right-clicking just brings up help options. I can drag the missing-red-marked target above or below the working black target, but it doesn't let me delete it.
This missing red target only seems to appear in this edit schemes dialogue.
In my main project/target window, I just have the one good target there.
Any ideas how to clean this up and delete this missing target?
What worked for me was to designate another executable (or none) in the existing scheme's various actions (run, test, etc.). It's the fact it's in use in the scheme's actions that prevents its deletion. I discovered this during my research for Mastering Xcode 4 (yes, shameless plug). :-)
Try creating a brand new scheme (via "New Scheme" or "Manage Schemes...") and start using that.
Once your new scheme is building properly and is set as a default, you should be able to delete the old scheme with the bogus "missing" target.
The real issue here is explained by Joar Wingfors in the Xcode-users mailing list (emphasis mine):
In the scheme sheet you cannot delete things from one tab that some
other tab depend on. In this case you probably have to delete the
target from the test tab before you can delete it from the build tab.
Or something along those lines.
I had the exact same problem. Solved by closing the xCode and externally editing the schema file to delete the bundlableResource section for the missing library. Not the safest of all methods but it works.
First delete all schemes and then generate the schemes again. Work for me .
What Joshua said, a bit tailored. Go through all various actions and change the missing executable to an existing one.
In your case, go to 'Profile' and switch to the new app. Same if you encounter this in 'Test' tab.
