Count lines of code in SWIFT Xcode project

Count lines of code in Xcode project

1. Open Terminal
2. cd to your Xcode project
3. Execute the following when inside your target project:

find . -name "*.swift" -print0 | xargs -0 wc -l

find . -path ./Pods -prune -o -name "*.swift" -print0 ! -name "/Pods" | xargs -0 wc -l

(excluiding ./Pods from find)

Mixed ObjC + Swift project:
find . -type d \( -path ./Pods -o -path ./Vendor \) -prune -o \( -iname \*.m -o -iname \*.mm -o -iname \*.h -o -iname \*.swift \) -print0 | xargs -0 wc -l

How to exclude Comments and empty lines while counting the total number of lines, please suggest.

For Jenkins Integration I suggest using cloc and SLOCCount Plugin.

Our cloc command looks something like this
cloc . --exclude-dir=Carthage,Frameworks,generated,.idea,output,derivedData,Fastlane --not-match-d=.*\.framework --by-file --xml --out=output/cloc.xml

How would you exclude test files?

You'd just add your test directories into the list of exclude-dirs. Here is an example to actually only count Swift code and Pods and Tests are excluded:

cloc . --exclude-dir=.\*Tests,Pods,Carthage,Frameworks,generated,.idea,output,DerivedData,Fastlane,.\*.xcodeproj,.\*.xcworkspace --include-ext=swift
