I am using Xcode 7 beta 5 and I get the error message “UIStackView before iOS 9.0”. I see that at least one other person has encountered this problem, but their solution does not work for me. The purpose of my deployment is 9.0.
Here is a link to some useful screenshots (since I guess I can’t post photos yet): https://docs.google.com/document/d/178kcpuzzeQM6lBAso4srStc0pnDL_2x1Z59_QevcKoc/edit?usp=sharing
In addition, I already uninstalled and re-created the user interface once and did not help. Any insight is greatly appreciated!
Here is an open source project called OAStackView .
With OAStackView, you can be compatible with iOS7.
Hope this helps you.
Edit:
If the error still appears in the interface builder, try changing the project deployment target to 9.0
