Resolve the issue ‘App is ambiguous for type’ with Realm in your SwiftUI project

I recently realized that there is a problem while integrating realm into swift. The problem was caused by Dependency Name Collision. Let’s solve it in 3 seconds.

Dependency Name Collision Example

Realm

This is the problem I recently found. When you use Realm, compilation error occurs with “‘App’ is ambiguous for type lookup in this context”.

The origin of the problem

Realm is using `App` name

Your SwiftUI App is using `App` name

This is because RealmSwift is using App and clearly your SwiftUi app is also using App protocol. How do I resolve this issue?

Issue Solved

Issue Solved with `SwiftUI.App`

By specifying that you are importing App from SwiftUI, this issue can be easily resolved!

Conclusion

• Realm uses App in its module and SwiftUI uses App in its module. It causes ambiguous type error.
• Just by specifying you’re importing App from SwiftUI, this issue can go away for good in a second.
