Error when building the project in Xcode
ios, objective-c, xcode
Solution
As this error says you have duplicated images AppIcon and LaunchImage. To sort it just make copy of it and remove it from your project (have a look in Images.xcassets and remove it as well). After that import it again to Images.xcassets.
Problem
I get following error while building the project. Clening also didn't help. No idea what went wrong all of a sudden ``` CompileAssetCatalog /Users/Mayu/Library/Developer/Xcode/DerivedData/Pizza_to_Go-dohdzfdfbyycqrhirbysuinqfuzf/Build/Products/Debug-iphonesimulator/Pizza\ to\ Go.app Pizza\ to\ Go/Images.xcassets Pizza\ to\ Go/Images.xcassets cd "/Users/Mayu/Documents/development/git/pizzatogo/iPhoneApp/Pizza to Go" setenv PATH "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/actool --output-format human-readable-text --notices --warnings --export-dependency-info /Users/Mayu/Library/Developer/Xcode/DerivedData/Pizza_to_Go-dohdzfdfbyycqrhirbysuinqfuzf/Build/Intermediates/Pizza\ to\ Go.build/Debug-iphonesimulator/Pizza\ to\ Go.build/assetcatalog_dependencies.txt --output-partial-info-plist /Users/Mayu/Library/Developer/Xcode/DerivedData/Pizza_to_Go-dohdzfdfbyycqrhirbysuinqfuzf/Build/Intermediates/Pizza\ to\ Go.build/Debug-iphonesimulator/Pizza\ to\ Go.build/assetcatalog_generated_info.plist --app-icon AppIcon --launch-image LaunchImage --platform iphonesimulator --minimum-deployment-target 7.0 --target-device iphone --compress-pngs --compile /Users/Mayu/Library/Developer/Xcode/DerivedData/Pizza_to_Go-dohdzfdfbyycqrhirbysuinqfuzf/Build/Products/Debug-iphonesimulator/Pizza\ to\ Go.app /Users/Mayu/Documents/development/git/pizzatogo/iPhoneApp/Pizza\ to\ Go/Pizza\ to\ Go/Images.xcassets /Users/Mayu/Documents/development/git/pizzatogo/iPhoneApp/Pizza\ to\ Go/Pizza\ to\ Go/Images.xcassets /* com.apple.actool.errors */ : error: There are multiple app icon set instances named "AppIcon". : error: There are multiple launch image set instances named "LaunchImage". /* com.apple.actool.compilation-results */ /Users/Mayu/Library/Developer/Xcode/DerivedData/Pizza_to_Go-dohdzfdfbyycqrhirbysuinqfuzf/Build/Products/Debug-iphonesimulator/Pizza to Go.app/Assets.car /Users/Mayu/Library/Developer/Xcode/DerivedData/Pizza_to_Go-dohdzfdfbyycqrhirbysuinqfuzf/Build/Intermediates/Pizza to Go.build/Debug-iphonesimulator/Pizza to Go.build/assetcatalog_generated_info.plist ```
