During iOS development, especially in the early days of iOS development, there will be a variety of errors. Some errors are caused by developers’ unfamiliarity or negligence, while others are irrational errors that can be resolved by restarting Xcode or restarting your computer.

So this blog post shares a common and classic error message, this error message is generally used when using OC visual programming, such as creating a new XIB file, and then dragging the control, when the control is associated with the operation, if the drag line “posture” is not correct, “Could not insert new outlet Connection :Counld not find any information for the class named XXX…” “, the cause of the error is not discussed, but the solution is described as follows.
