I’m following chapter 4, I get the following error after running bootstrap.sh in the starter directory:

**error: Playground.playground:24:8: error: could not build Objective-C module ‘RealmSwift’**  
**import RealmSwift**

This obviously is a podfile problem, when I look for podfiles:

$ find . -name “Podfile”

./BackLinks-challenges/Podfile  
./starter/Realm/examples/installation/watchos/swift/CocoaPodsExample/Podfile  
./starter/Realm/examples/installation/watchos/objc/CocoaPodsExample/Podfile  
./starter/Realm/examples/installation/osx/swift/CocoaPodsExample/Podfile  
./starter/Realm/examples/installation/osx/objc/CocoaPodsExample/Podfile  
./starter/Realm/examples/installation/ios/swift/CocoaPodsExample/Podfile  
./starter/Realm/examples/installation/ios/objc/CocoaPodsExample/Podfile  
./starter/Realm/examples/installation/ios/objc/CocoaPodsDynamicExample/Podfile  
./starter/Realm/examples/ios/objc/Podfile  
./BackLinks-final/Podfile  
./BackLinks-starter/Podfile

I’d assume running bootstrap.sh would build this, but it’s not. What Podfile do I add RealmSwift in? Or am I doing something completely wrong?

REALM\_VERSION=“3.13.1”
