iOS Convert to xCode 10.1 swift 4.0

[rich1812]

Hello, I downloaded a xCode project, I believe it was done in xcode 8.x. Swift 2.x.. I opened it in the latest xCode 10.1. When I open the project, I had a bunch errors and warnings. I managed to fix them except 2 errors, -

Showing All Messages

Build system information

error: Value for SWIFT_VERSION cannot be empty.

How can I fix this? Thanks.

Go to the Projects or Targets Build Settings.
Scroll down to "Swift Compiler - Language" setting
And then select the Swift Language Version your Project or Target is using.

I believe you can have "Unspecified" Selected for the Project setting.
But must select a Swift Version number for the Target.

Make sure your code source files contain the Swift syntax that matches your Language Version Setting.
