When xcode compile a project, it always stop when encountrt some error.
Is it possible to make xcode compiling no stop?
I hope to count error amount.
your comment welcome
You may try to two possible solutions -
enable Xcode -> Preferences > General > Continue Building After Errors
Set a flag "-ferror-limit=0" to compiler flags in the project settings under the "Language" section of the "Build Settings" tab.
Every .m (source) file is compiled separately, so you can always count how many files failed to compile.
Usually, you cannot count the errors in one single file. The reason is simple, the compiler cannot recover from some errors.
If you know something about compilers, there are two important phases - the syntax analysis and semantic analysis. Semantic analysis triggers errors such as "unknown variable" or "unknown method" and the compiler can usually recover pretty easily. The syntax analysis is a problem though. A missing brace, a missing semicolon, a missing parenthesis - all of those are errors triggered by syntax analysis. When an error is encountered, the compiler tries to recover so that it can continue the compilation. For instance, recovering from a missing parenthesis means adding the missing parenthesis and continue. Sometimes that works, other times it doesn't. If it doesn't, you will get tens or hundreds of errors. Then the compiler will stop. If there are too many errors, it doesn't make sense to try to compile.

I have an iOS project that depends on several external dependencies (swift frameworks, objective C projects, and vanilla C). All of a sudden (with no code changes that I can see), the builds have begun failing, flagging errors:
I am on Xcode 11.3.1 with Swift 5.
This error persists even after reverting to an earlier revision of the project that was known to compile, and when attempting to build on a new machine with a completely fresh clone of the project.
I am at a complete loss at this point, any help would be greatly appreciated.
EDIT: I've noticed for some reason my compiler version was set to Swift 4.2 in my Build Settings. Now the project builds....sort of. When I try to archive the project I still have the same problem, but a normal build with Product->Build works.
Unfortunately I am unable to reproduce this error in a small project as I have no idea what change caused it to begin happening.
The solution for this problem was to disable optimizations in the build settings (from "optimize for speed" to "no optimization").

I am working on a Xcode8.3.3 iOS10.3 compatible project and it has some UI tests (I had written them) associated with it which were building successfully and passing until the recent dependency pod library update, in spite of warnings in the warnings tab.However, after updating my dependent pod library to newer version, the build for UI tests are failing showing same warnings that were present already as "reason", but project build is passing. Could it be due to some misconfiguration(I did not make any configuration changes though other than incrementing pod library version) or some error check set to strict or something else? No hint on what could be the issue. Do suggest.
(Note: there is no specific code that I think will be required as this is a problem with only UI tests not building and suggestions of build config -- zero code changes compared to UI tests that were building earlier -- if required I am ready to show, let me know what I have to show).
I am a newbie to Xcode. It seems I somehow clicked on disable tests option which comes when we try to run tests from the fifth icon in left pane and select test to run.Hence, the build was failing and it never notified me I had disabled tests.Now I have found this and enabled this option and it's working fine.
As you see this has nothing to do with code and thanks for not hinting out this could be an issue :) and all your kind down votes.

XCode has recently stopped showing all build errors and I'm at a loss for how to correct it. Whether it be something like forgetting to put in an initial view controller, misspelling/not declaring a variable name, or pretty much anything else that would cause the project not to build will no longer show up. I've built the project on other Macbooks and it showed me the errors so I was able to correct it, but I can't get it to show on mine.
The issue might occur because of Xcode.
(1) Quit and relaunch Xcode.
(2) Clean (⌘+shift+K) and build (⌘+shift+B) your project.
If that not case, check out he answer here by Kris i.e.
Click the last icon in the top bar of the left most panel in your
Xcode window to reveal the secret Archive build errors.

Recently I have learned how to program a iOS project. I coded by followed a tutorial.But the same code the different result. Maybe there is something wrong with header file? I imported a header file in the same project.Although it made Xcode no warn about "use of undeclared identifier 'UILocalNotification' ", it did't make the effect that I want.And I want to say ,in the tutorial the teacher did't have imported this header file .So mistake must not be here.
Judging by the error, it looks like you might have used a UILocalNotification somewhere in your code that you did not include the proper #import for.
What tutorial were you using? Is there a 'completed project' that they provide that you can compare your code to?
It might be helpful to include any relevant code (from your project) that will aid in the process of troubleshooting the error.
As a side note: Check how recently the tutorial was written-- if it is an older one (for previous versions of XCode), you may need to alter, remove, or add some code in order to fix certain errors.

Wondering if I can get some direction here; I've got 18 Warnings (which I think are all deprecated functions for SDK(s) for in-ap-advertising. I'm working through them separately. The only error I have is as follows, causing me to be unable to run on both iOS Simulators and on physical devices.
clang: error: no such file or directory: '_ObjC'
The masses of text immediately above this give file paths for what looks like all the compile source paths.
I can confirm that the Build Settings - Linking-Other Linker Flags contains "-all_load" and "_ObjC".
I've had a look about and have found similar questions and tried to transpose the answers into something that will relate to my Error, but am going a bit mad right now because it's probably something really simple :|
Please let me know if you require any further information or screenshots etc., etc.

I'm Mad
That should be -ObjC, a hyphen, not _ObjC, an underscore.
