'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.
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.
