Xcode 6 GM - Build error when copying generated "MyAppName-Swift" header file?

Question

Below is the error I'm getting when building my application. Does anyone have experience with this error?

ditto: can't get real path for source '/Users/MyUsername/Library/Developer/Xcode/DerivedData/MyAppName-fwxrneawhopjkqcpeoykduytrgwv/Build/Intermediates/MyAppName.build/Debug-iphoneos/MyAppName.build/Objects-normal/arm64/MyAppName-Swift.h'

Command /usr/bin/ditto failed with exit code 1

Any help would be great!

If more info is needed, please ask. :)

Here's a thread I made on Apple's developer forums about my problem. – Indefinable

Answer 1

Crazy right? Did the super clean, Command - Option - Shift. Cleared it up. Was stunned that it worked.

Did for me too. I also had an error stating: "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed". Both disappeared. This all happened to me when upgrading to Xcode 7.2. – Oligoclase

Answer 2

I had this problem too. I realized that by commenting out most of my swift code it would build properly. Gradually, line by line, I uncommented code until I found an error in my swift code that was masked by this error. Now the app builds just fine.

I only had this problem with my Swift framework. Once I decided to just add the framework's source code to my project directly (rather than building it as a a framework) did it work properly. Quite strange. – Indefinable

Answer 3

I had this issue, when I accidentally removed some swift file from disk.

Answer 4

Just Clean and build the code, it will work fine. clean -> shift + command + K.

Do a "Super Clean"

1. Clear derived data folder Xcode, Preferences, Locations, Click First Arrow

2. Clean build folder Command + Alt + Shift + K

3. Clean Project Command + Shift + K

Restart Xcode for good measure. MAGIC
