'Framework not found' in Xcode

Try deleting Bolts.framework from linked framework and re-add it. Also, in your Framework Search Path keep path until Bolts.framework like $(PROJECT_DIR)/Bolts if it is inside Bolts folder at your project directory path.

error: Framework not found

If you use CocoaPods try to run:

pod deintegrate
pod update

Also use .xcworkspace instead of .xcodeproj

I'm pretty new to iOS development. Apparently this problem for me was a result of opening the .xcodeproj Xcode project instead of the .xcworkspace Xcode workspace. I opened the workspace instead and the error has gone away.
