Realm Swift in Xcode 10.2 - ERROR: Module compiled with Swift 4.2 cannot be imported by the Swift 5.0 compiler

manpreet Best Answer 2 years ago

I recently had to update to Xcode 10.2 since my iPhone automatically updated to iOS 12.2 and I have to use it for some in-app purchase testing.

The project uses Swift 4.2 and Realm.

I knew I had to update Realm so here is what I did...

1. Downloaded realm-swift-3.14.1
2. In Xcode, I replaced the frameworks with the latest from the download in my case the ones inside folder, swift-10.2.

"In the past the Realm folders used to be labeled as the Swift version now they are labeled per the Xcode version"

3. Compiled and then I got the following error.

Module compiled with Swift 4.2 cannot be imported by the Swift 5.0 compiler: /Users/userName/MyApp/RealmSwift.framework/Modules/RealmSwift.swiftmodule/i386.swiftmodule

What am I missing?

What do I need to do to be able to use my Swift 4.2 project inside Xcode 10.2 and RealmSwift?

Is RealmSwift ready for Xcode 10.2?
