Swift can't use protocol from framework

Question

I create simple framework in Swift that contain public protocol. I did add it to my project, added import, and try to add variable to my class that is actually a protocol that my framework declare. However, i got an error:

 Use of undeclared type 'PaymentTerminal'

I declare it like this:

public protocol PaymentTerminal: class {

}

In my class, i add import my framework :

import PaymentTerminalInterface

Then try to:

var terminal: PaymentTerminal!

And got an error i describe above.

When i try to cmd+press on PaymentTerminal in var terminal: PaymentTerminal! i successfully dig in protocol declaration.

我将框架中的部署iOS目标版本更改为与我的应用程序相同后，问题已解决。
