Failed to render instance of IB Designables

objective-c xcode swift interface-builder ibdesignable

Finally, I solved this issue by adding $(CONFIGURATION_BUILD_DIR) in the target's build settings' Runpath Search Paths field.

Plus, there are some additional steps you might need to do with your Xcode.

Clear Xcode derived data for the project. They are in ~/Library/Developer/Xcode/DerivedData
Clean your current build by pressing ⌘⇧K
Build your project
In storyboard go to Editor menu and do Refresh All Views; wait for build to be completed and errors should be gone

If you have the same issue building a Mac App, adding @loader_path/../Frameworks to Runpath Search Paths solved this for me.

for me it works to close xcode and reopen it again. No errors after.Thanks.
