Disabling and enabling warning in xcode - xcode

Is it possible to disable warnings for particular piecies of code in xcode?
I'm using a library I didn't write myself, and it creates hundreds of warnings. This makes it very unclear to find warnings related to my code. Is it possible to disable when #import-ing the headers and re-enabling warnings immediately after?
I remember this was possible in some other IDE, maybe Visual Studio, maybe with some #pragma. Anything similar in xcode?
Thanks!

Open your project in XCode, then right click on your target in the Targets folder. Select "Get Info" form the drop down menu and then scroll down to the section for the compiler warnings (GCC 4.0 Warnings on my box). Here you can disable the checkboxes for the various warnings you have active. Also check the value of "Other Warning Flags". This could include -Wall or -WMost which will enable other warnings. You can remove that and hopefully your warnings will not appear.

Disable storyboard warnings

I avoid getting warnings in my swift code. However when it comes to storyboard requirements it's a bit harder for me.
So for now i just want to disable xcode showing warnings regarding storyboard issues.
I have tried the following without success:
Disable show warnings option
As you have mentioned the option Show warnings under Interface Builder Storyboard Compiler -Options must be kept no, for suppressing warnings related to your storyboard.
What you missing to do
Also after that you can enable and disable this option from right bottom position of warnings tab in Issue navigator.
Example:
That way you can toggle easily.
If you just want to hide warnings for storyboard, it looks like you've done it correctly. However, you do need to restart Xcode for the updated preferences to take effect.
If that doesn't work, you can also try this:
Navigate to build settings and go to the Compile Sources phase. Double-click in the Compiler Flags column for the storyboard and enter -w to turn off all warnings for that file.

How to add compiler flags on codeblocks

I've been trying to compile a simple multithreaded piece of code I found online in an effort to learn how to multithread.
To run this piece of code I need to use the compiler flags: -pthread and -std=c++0x.
But whenever I try to add the flags the build log doesn't show them being used.
I've tried some generic tips online to get these to work, but none of them worked. Can someone help?
I've tried other advice online to add compiler flags to code blocks, but when I do that and check the build log none of them appear.
Because This Question was marked as Duplicate, even if doesn't have to do with it, because there is about Linker Flag and here is about Compiler Flags, I will post My answer HERE.
You will have to go to Settings -> Compiler... and next you'll have to click on Linker Settings TAB.
On the right side you will see Other Linker Options.
There you have to type -lpthread and press OK.
You may need to click on rebuild after that.
Open your project and then go Project > Build Options > Compiler Flags .
You can tick boxes in the "Compiler Flags" tab, and you can write other options in the "Other Options" tab.
Do one or the other, e.g. don't tick the "-std=c++98" box and also put "-std=c++11" in the Other Options. This will end up in both options being passed to the compiler.
Another option instead of using the "other options" is to create a custom compiler flag. So in addition to a compiler flag, you can specify a linker flag. In the case of the -pthread (which I also was having trouble with) it looked like it needed the linker flag as well, as mentioned by Michi
One can create a new compiler flag by right clicking and selecting the new option
add options: menu->project->properties->Build targets tab->Build options button

Is it possible to disable specific compiler warnings?

I am trying to suppress specific compiler warnings, namely System.Data.OracleClient.OracleConnection' is obsolete. I came upon these questions here:
How to disable specific warnings for the entire solution?
Globally suppress c# compiler warnings
...but they don't seem to apply to VS2013. When I go to my project's properties, I don't see a Build tab. I see a Compile tab, but it doesn't appear to have a place to specify warning messages to suppress. I see a section there called Warning configurations, but I don't see the warning I am looking for.
Update: It turns out that I am trying to do this for VB.NET. Thanks to a link provided by the selected answer, you have to edit the project file's XML and supply the warning code in the <NoWarn></NoWarn> tag. However, you have to know the warning code which is hidden in the error list. One way to get it is to open the output window and build the project. In my case, the warnign code is 40000. It shows as BC40000, but I had to remove the BC. After rebuilding the project, the warning messages went away.
To suppress specific warnings for Visual C# or F#:
In Solution Explorer, choose the project in which you want to suppress warnings.
On the menu bar, choose View, Property Pages.
Choose the Build page.
In the Suppress warnings box, specify the error codes of the warnings that you want to suppress, separated by semicolons, and then rebuild the solution.
Check out here for more info on how to suppress specific warning for Visual C++ and Visual Basic.
Another ways is to use #pragma warning can enable or disable certain warnings.:
#pragma warning disable warning-list
#pragma warning restore warning-list
warning-list
A comma-separated list of warning numbers. Enter the numbers alone, without the "CS" prefix.
When no warning numbers are specified, disable disables all warnings and restore enables all warnings.
Yes, it is possible.
#pragma warning disable 'warning-number-list'
where warning-number-list is a comma separated list of warning numbers to disable, e.g. 1004
This will disable the warning from its point of declaration to the end of the current file unless re-enable with:
#pragma warning restore 'warning-number-list'.
These pragmas are placed inline in your code at the site of where you wish to disable/restore the warnings.
I believe there is also a place on the Project properties tabs to specify warnings to disable, as you mentioned.

How can I disable javascript compile warnings in VS 2010?

Visual studio seems intent that my javascript code is bad, mostly because it has no knowledge of jquery or some plugins I am using. Therefore, every time I compile my product it gives me a lot of warnings, most of them are incorrect ($ is not defined, window is not defined, etc...).
I have /// <reference path="" /> tags setup in my javascript with intellisense working properly so I know these are just not real issues.
How can I disable these warnings?
edit to be clear, I need these disabled because it's causing 100+ warnings that are making me lose sight of REAL c# warnings.
I had the exact same issue you were having: 100s of incorrect errors every save. For me the issue was with Chirpy, which was a prerequisite for another extension. For whatever reason on my end, Chirpy was not in my Extension Manager so it took me a while to find.
Check and see if you have it installed. If so disable JSHint.
Tool -> Options
Chirpy -> JSHint
Uncheck: Run JS Hint
try this and let me know if it works.
Enter the options through Tools > Options.
In the tree to the left, choose Text Editor > JScript > Miscellaneous. Uncheck "Show syntax errors".
I don't have a javascript source file on the computer I'm on at the moment to test this, but you may be able to use the #pragma command to disable particular warnings:
#pragma warning disable will disable all warnings, and #pragma warning restore will restore all warnings when placed at the end of your code block. You can also tell it to disable only particular warnings, such as #pragma warning disable 0219,0168.

Interesting I am not able to reproduce your issue in neither VS2010 "website" project nor vs2010 "web application" project. It has to do with the add-ons that you installed. Probably you may have a setting in that add-on (who ever is causing this) to disable warnings.
To me the warning sounds like the add-on (who ever is causing this) is not intelligent enough. Try the below changes and see if that helps.
If you have master page then try move the jquery*.js script reference from master page to your actual page
Move all your javascript code into a js file instead of writing it them under script tag
Thanks,
Esen
What about this one?
To disable a single compiler warning
With a project selected in Solution Explorer, on the Project menu, click Properties.
Click the Compile tab.
In the Warning configurations table, set the Notification value for the warning to None.
or perhaps this one
Tools > Options > Text Editor > JScript > Misc > Show errors as warnings( uncheck only this )

Why aren't Xcode breakpoints functioning?

I have breakpoints set but Xcode appears to ignore them.
First of all, I agree 100% with the earlier folks that said turn OFF Load Symbols Lazily.
I have two more things to add.
(My first suggestion sounds obvious, but the first time someone suggested it to me, my reaction went along these lines: "come on, please, you really think I wouldn't know better...... oh.")
Make sure you haven't accidentally set "Active Build Configuration" to "Release."
Under "Targets" in the graphical tree display of your project, right click on your Target and do "Get Info." Look for a property named "Generate Debug Symbols" (or similar) and make sure this is CHECKED (aka ON). Also, you might try finding (also in Target >> Get Info) a property called "Debug Information Format" and setting it to "Dwarf with dsym file."
There are a number of other properties under Target >> Get Info that might affect you. Look for things like optimizing or compressing code and turn that stuff OFF (I assume you are working in a debug mode, so that this is not bad advice). Also, look for things like stripping symbols and make sure that is also OFF. For example, "Strip Linked Product" should be set to "No" for the Debug target.
In Xcode 7, what worked for me was:
Make sure that the Target > Scheme > Run - is in Debug mode (was Release)
Make sure to check the option "Debug executable":
Go to the Xcode Debugging preferences.
Make sure that "Load Symbols lazily" is NOT selected.
I was just having this same issue (again). After triple-checking "Load symbols lazily" and stripping and debug info generation flags, I did the following:
quit Xcode
open a terminal window and cd to the project directory
cd into the .xcodeproj directory
delete everything except the .pbxproj file (I had frank.mode1v3 and frank.pbxuser)
You can accomplish the same task in finder by right/option-clicking on the .xcodeproj bundle and picking "Show Package Contents".
When I restarted Xcode, all of my windows had reset to default positions, etc, but breakpoints worked!
One of the possible solutions for this could be ....go to Product>Scheme>Edit scheme>..Under Run>info>Executable
check "Debug executable".
For Xcode 4.x:
Goto Product>Debug Workflow and uncheck "Show Disassembly When Debugging".
For Xcode 5.x
Goto Debug>Debug Workflow and uncheck "Show Disassembly When Debugging".
Another reason
Set DeploymentPostprocessing to NO in BuildSettings - details here
In short -
Activating this setting indicates that binaries should be stripped and
file mode, owner, and group information should be set to standard
values. [DEPLOYMENT_POSTPROCESSING]
See this post: Breakpoints not working in Xcode?. You might be pushing "Run" instead of "Debug" in which case your program is not running with the help of gdb, in which case you cannot expect breakpoints to work!
Issue
Background
Xcode: 13.0
code: Objective-C
Issue: added breakpoint, but not work
(possible) Reason and Solution
Reason: Xcode bug
Solution: Product ->Clean Build Folder, then retry debug (multiple time)
Reason: disabled Debug
Solution: enable it: Product->Scheme->Edit Scheme->Run->Info
Build Configuration set to Debug
choose/select/enable: Debug executable
Reason: disabled all breakpoint
Solution: enable it: Debug panel -> click breakpoint icon
Reason: debug info be optimized
Solution: not optimize
click Project -> Build Settings -> Apple Clang - Code Generation -> Optimization Level -> Debug make sure is None[-O0]

XCode's Symbolic breakpoint not work
Background
XCode crash log
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSCFConstantString stringByAppendingString:]: nil argument'
add XCode symbolic breakpoint
-[__NSCFConstantString stringByAppendingString:]:
but breakpoint not working
Solution
change to:
-[NSString stringByAppendingString:]
related doc: stringByAppendingString:
Solution for me with XCode 9.4.1 (did not stop at any breakpoint):
Under build Target -> Build Settings -> Optimization Level:
Switched from "Optimize for speed" -> "No optimization" (now it's slower but works)
What solved it in my case was quite simple, in Xcode - Product - Clean Build Folder followed by Product - Run (not the Play Xcode button).
(Had the issue on Xcode 11 -beta 4 after switching to unit testing with Xcode play button long press)
This had me in Xcode 9 for half a frustrating day. It ended up been a simple debug setting.
Go Debug > Debug Workflow and make sure 'Always Show Disassembly' is turned off. Simple as that. :(
Came to this page with the same problem (C code in Xcode 6 not stopping at breakpoints) and none of the solutions above worked (the project was practically out of the box, settings-wise, so little chance for any of the debugger settings to be set to the wrong value)...
After wasting quite some time reducing the problem, I finally figured out the culprit (for my code):
Xcode (/LLVM) does not like Bison-style #line preprocessor commands.
Removing them fixed the problem (debugger stopped at my breakpoints).
For Xcode 4:
go Product -> Debug -> Activate Breakpoints
This is applicable for all Xcode version. Shortcut key is: command key + Y. Press this key combination to activate/deactivate breakpoints.
I have a lot of problems with breakpoints in Xcode (2.4.1). I use a project that just contains other projects (like a Solution in Visual Studio). I find sometimes that breakpoints don't work at all unless there is at least one breakpoint set in the starting project (i.e. the one containing the entry point for my code). If the only breakpoints are in "lower level" projects, they just get ignored.
It also seems as if Xcode only handles breakpoint operations correctly if you act on the breakpoint when you're in the project that contains the source line the breakpoint's on.
If I try deleting or disabling breakpoints via another project, the action sometimes doesn't take effect, even though the debugger indicates that it has. So I will find myself breaking on disabled breakpoints, or on a (now invisible) breakpoint that I removed earlier.
I've had my breakpoints not work and then done Build / Clean All Targets to get them working again.
I think the problem could be incompatibility between device versions and Xcode. I have this problem when attempting to debug on my iPhone 4S running iOS 5.0.1. I am still using Xcode 3.2.5. I got the symbols from the handset by selecting "use this device for development" in the Organiser window. This phone refuses to breakpoint however. My old 3GS will breakpoint, same Xcode project, same settings... just different device and it's running iOS 4.0. I guess this is an Xcode bug in 3.2.5, since I have the symbols. Having tried all the solutions posted here so far, I have decided the solution to my problem is to go ahead and upgrade to XCode 4. Perhaps you cannot debug effectively unless your base SDK is at least as high as the system on which to debug. Maybe that's obvious - can anyone confirm?
Edit: I will update when I can confirm this is true.
Deleting my Build folder solved the problem for me.
If all else fails, instead of a breakpoint, you can call the following function:
void BreakPoint(void) {
int i=1;
#if !__OPTIMIZE__
printf("Code is waiting; hit pause to see.\n");
while(i);
#endif
}
To resume, manually set i to zero, then hit the resume button.
It has happened the same thing to me in XCode 6.3.1.
I managed to fix it by:
Going to View->Navigators->Show Debug Navigators
Right click in the project root -> Move Breakpoints (If selected the User option)
(I also Selected the option share breakpoints, even though I'm not sure if that necessary).
After doing that change I set the Move breakpoints options back to the project, and unselecting the Share breakpoints option, and still works.
I don't exactly know why but this get my breakpoints back.
For this, and also for Xcode 6 and above make sure that the breakpoint state button is activated (the blue arrow-like button):
In Xcode 4
- Product menu > Manage Schemes
- Select the scheme thats having debugging problems (if only one choose that)
- Click Edit button at bottom
- Edit Scheme dialog appears
- in left panel click on Run APPNAME.app
- on Right hand panel make sure youre on INFO tab
- look for drop down DEBUGGER:
- someone had set this to None
- set to LLDB if this is your preferred debugger
- can also change BUILD CONFIGURATION drop down to Debug
- but I have other targets set to AdHoc which debug fine once Debugger is set
I found the problem. Somehow the "Show Disassembly when debugging" was enabled in my XCode which creates that problem. When I disabled it, all my debugger stopped in my source code.
You can find it under: Product->Debug Workflow->Show Disassembly when debugging.
You can Activate / Disactivate Breakpoints in dropdown menu
I tried all the above things but for me only deactivating the debugging breakpoints once and then activating them worked.
When setting your break point, right click and you should get several options about how the break point is handled (log vars and continue, pause execution, etc)
Also make sure the "Load Symbols lazily" is not selected in the debug preferences.
(Applies to Xcode 3.1, not sure about past/future versions)
Also make sure that the AppStore distribution of the app is not also installed on the device.
Another thing to check is that if you have an "Entitlements" plist file for your debug mode (possibly because you're doing stuff with the Keychain), make sure that plist file has the "get-task-allow" = YES row. Without it, debugging and logging will be broken.
There appears to be 3 states for the breakpoints in Xcode. If you click on them they'll go through the different settings. Dark blue is enabled, grayed out is disabled and I've seen a pale blue sometimes that required me to click on the breakpoint again to get it to go to the dark blue color.
Other than this make sure that you're launching it with the debug command not the run command. You can do that by either hitting option + command + return, or the Go (debug) option from the run menu.
I have Xcode 3.2.3 SDK 4.1 Breakpoints will fail at random. I have found if you clean the build and use the touch command under build they work again.
