Xcode fails without specifying and errors

Question

All of a sudden my project fails to build in Xcode. If I look at the log I see all the needed dependencies being built, and then I get a strange error:

Verify fi         


        

Answer 1

For me it was fixed by changing to the new build system(in File -> Project settings)

I have Xcode 11.7

Answer 2

I have encountered same issue without having any code changes for my project running on Xcode 9.2. It looks like if you have some run scripts or external build systems attached to the project, this might cause an issue. Try committing or discarding changes and build again. If it still persist, delete local repo and clone again. Also maintain smaller folder names for project location.

Answer 3

I know this is super late to answer but I'm answering since none of the above solutions worked. For me restarting, clean building, deleting derived data nothing worked. Because the issue was not due to any zombie objects or something like that. I'm using Xcode 11. I think it's an Xcode bug that sometimes errors are not shown in the issue navigator. But don't worry check the build report in Report navigator(The last tab in project navigator: the one that looks like a comment box with lines in it. or simply cmd + 9).

Click the relevant build and resolve the issue, mine was missing file in pods directory.

Answer 4

With Xcode 5.0.0, this error was caused after an update to the CLI tools.

Updating to Xcode 5.0.1 and installing all the required components again still didn't fix the error. However, 5.0.1 was kind enough to actually emit an error that was useful.

/bin/mkdir -p /Users/xxx/Documents/XCode/SampleApp/bin/SampleAppDebug.app/Contents

error: (null)

This lead me to look at the bin folder, and find out that the 5.0.0 build with broken CLI tools had made a symlink in bin/ to the derived information folder with SampleAppDebug.app, which for some reason it could not write to.

I manually removed all contents of the bin/ folder and rebuilt without errors.

Answer 5

I was hitting this error and it infuriated me for an hour or so. The answer below helped me out a lot: essentially your machine has a ton of running processes, XCode can't handle it, and rebooting your machine is the best answer.

Answer 6

did you set "Perform Single-Object Prelink" to Yes? try turn it off.

i had the similar problem. i have tons of files in a static library. reducing the number of files or setting "Perform Single-Object Prelink" to NO solved my problem.
