    <p>There seems to be lots of posts regarding that error message but I couldn't find one that has something to do with actual code. I have an Xcode 4.0 project called <code>prog1</code>, and inside it is a single file <code>main.m</code>:</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; @interface Fraction : NSObject -(void) print; -(void) setNumerator: (int) n; -(void) setDenominator: (int) d; @end @implementation Fraction { int numerator; int denominator; } -(void) print { NSLog(@"The fraction is %i/%i.", numerator, denominator); } -(void) setNumerator: (int) n { numerator = n; } -(void) setDenominator: (int) d { denominator = d; } @end int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; Fraction *f = [[Fraction alloc] init]; [f setNumerator:5]; [f setDenominator:6]; [f print]; [pool drain]; return 0; } </code></pre> <p>This is the complete error message:</p> <pre><code>ProcessPCH /Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/PrecompiledHeaders/prog1-Prefix-ethcjsncaxczlsgsnayacjarhmne/prog1-Prefix.pch.pth prog1/prog1-Prefix.pch normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler cd /Users/rh/Desktop/prog1/prog1 setenv LANG en_US.US-ASCII /Developer/usr/bin/clang -x objective-c-header -arch x86_64 -fmessage-length=0 -fdiagnostics-print-source-range-info -fdiagnostics-show-category=id -fdiagnostics-parseable-fixits -std=gnu99 -Wno-trigraphs -fpascal-strings -O0 -Wreturn-type -Wparentheses -Wswitch -Wno-unused-parameter -Wunused-variable -Wunused-value -Wshorten-64-to-32 -DDEBUG -isysroot /Developer/SDKs/MacOSX10.6.sdk -fasm-blocks -mmacosx-version-min=10.6 -gdwarf-2 -iquote /Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Intermediates/prog1.build/Debug/prog1.build/prog1-generated-files.hmap -I/Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Intermediates/prog1.build/Debug/prog1.build/prog1-own-target-headers.hmap -I/Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Intermediates/prog1.build/Debug/prog1.build/prog1-all-target-headers.hmap -iquote /Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Intermediates/prog1.build/Debug/prog1.build/prog1-project-headers.hmap -I/Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Products/Debug/include -I/Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Intermediates/prog1.build/Debug/prog1.build/DerivedSources/x86_64 -I/Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Intermediates/prog1.build/Debug/prog1.build/DerivedSources -F/Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/Products/Debug -c /Users/rh/Desktop/prog1/prog1/prog1/prog1-Prefix.pch -o /Users/rh/Library/Developer/Xcode/DerivedData/prog1-djucagjboveiuwcnycgafzuugucf/Build/PrecompiledHeaders/prog1-Prefix-ethcjsncaxczlsgsnayacjarhmne/prog1-Prefix.pch.pth clang: error: no such file or directory: '/Users/rh/Desktop/prog1/prog1/prog1/prog1-Prefix.pch' clang: error: no input files Command /Developer/usr/bin/clang failed with exit code 1 </code></pre> <p>I don't see anything wrong here, but then again I just started learning Objective-C.

    1. COLook under the issues tab of Xcode and see if there isn't some more detail provided there. There should be. Then the problem may be easier to understand, or you will have some more information to post here.

    2. CO@Monolo Just posted the complete error message. Also, I'm running on Mac OSX 10.6.7 if that's anything.

    3. COIf I understand correctly, the error is saying that it couldn't find a certain file (as quoted in the complete message above). I actually don't have `/Users/rh/Desktop/prog1/prog1/prog1/prog1-Prefix.pch` when I look through my file system but why is that and how do I change it?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
