SwiftKey should have Smart Space turned off in certain languages - like Norwegian - that have a large number of compound words. To make sure that Smart Space is working as it should, please:
- Open the SwiftKey app from your device
- Tap 'Languages'
- Press the menu button (three dots in the top right corner)
- Tap 'Update language'
- When 'Update' appears next to your language(s), press it
To see which languages have Smart Space turned off by default, consult the following list: What languages are currently supported in SwiftKey for Android?
