When I build my project and I don't know how, I got this type of warning:
Could not read serialized diagnostics file: Invalid File: Invalid diagnostics signature
It is just shows the name of class but did not mentioned any location.
Any advise?
This is new as of Xcode 11.5, as far as I can tell, and it happens when you interrupt a running build. The warnings disappear when you let a new build run to completion.

When I add a breakpoint in code, then I try to po something in lldb I get this error once, and it gets away after printing the variable again.
warning: Swift error in fallback scratch context: error: failed to load module 'AppName'
note: This error message is displayed only once. If the error displayed above is due to conflicting
search paths to Clang modules in different images of the debugged executable,
this can slow down debugging of Swift code significantly,
since a fresh Swift context has to be created every time a conflict is encountered.
I have 2 issues that only appear when executing flutter build web.
Sometimes flutter build web fails complaining (wrongly) about types that were not compatible (see below).
Sometimes the build process finishes but then the web app doesn't work: doesn't display anything and there are no messages in the console.
The error I mention is something like this:
% flutter build web
Target dart2js failed: Exception: lib/main.dart:24:31:
Error: A value of type 'ApiUsersRepository' can't be assigned to a variable of type 'UsersRepository'.
- 'ApiUsersRepository' is from 'package:my_app/api_users_repo.dart' ('lib/api_users_repo.dart').
- 'UsersRepository' is from 'lib/users_repo.dart'.
final UsersRepository usersRepository = ApiUsersRepository();

Error: Compilation failed.
The app is working in iOS and web when developing.
The solution
I changed all imports of my files like:
import 'package:my_app/users_repo.dart';
To:
import 'users_repo.dart';
More Details
Investigating the error about types, I found this issue, where the important part is this comment: after changing every import to relative format it resolves my problem.
So I did that, and it solved the 2 issues, the compilation error, and the runtime error.
for me I had to remove a package that was corrupted. c:\src\flutter.pub-cache\hosted\pub.dartlang.org\localstorage-4.0.0+1 Apparently, a file had become corrupted by me invertly. I removed the package and did a flutter pub get then recompiled and it worked.
When converting to use the new build system on Xcode 10, I get the following error in my output for several of my extension targets.
<unknown>:0: error: if any output files are specified, they all must be
Command CompileSwift failed with a nonzero exit code
I have looked for a solution online, but the only reference I can find to this error is in the Swift compiler source code itself.
https://www.google.com/search?q=error_if_any_output_files_are_specified_they_all_must_be
Does anyone know how this error is actually triggered, or what I can do to fix it?
Ok, I had the same problem with one of our projects. Building or Archiving are always stopped with the error <unknown>:0: error: if any output files are specified, they all must be.
The solution for us was to set Compilation Mode to Incremental instead of Whole Module.
This means, you have to ignore the Validate Project Settings warning:

how to resolve this error. It seems that there may some problems in the "pmem.c" file and i'll have to choose different git repository. but that would be a very complex thing, as now i have already done most of the things till here. I might have to see correct version of this file. please someone tell what should i do?
how to solve this errors.
please help..thankyou!
There are several errors in the message you pasted, both conflicting types and implicit declarations. Three things that you might want to verify:
did you choose the correct processor architecture (ARCH) and cross compiler definition
does the chosen architecture mix in files from another arch (this is difficult to check, but you can start by checking the location of the files that are mentioned in the error message)
check these files themselves, to see it this is a bug (very unlikely, but you never know) and that you actually have to change some code
error CS0583: Internal Compiler Error (0xc0000017 at address 7C812AFB): likely culprit is 'IMPORT'.
An internal error has occurred in the compiler. To work around this problem, try simplifying or changing the program near the locations listed below. Locations at the top of the list are closer to the point at which the internal error occurred. Errors such as this can be reported to Microsoft by using the /errorreport option.
c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll: error CS0586: Internal Compiler Error: stage 'IMPORT'
error CS0587: Internal Compiler Error: stage 'IMPORT'
error CS0587: Internal Compiler Error: stage 'PARSE'
error CS0587: Internal Compiler Error: stage 'BEGIN'
Our code does not generate any errors when compiling it in the VS2005 UI.
What could be causing this issue?
This question is likely dead, but for those coming here form Google:
Deleting your PDB files may be of help.

Additionally you may want to try turning off Incremental Compilation:

If I resolve it on our own build server, I will post updated information.
I fixed the problem by repairing the visual studio in the control panel in the following address:
