[SWIFT] ld: framework not found Crashlytics workaround

Before

Since the support for Crashlytics is until 2020/11/15, I was in a hurry to update to Firebase Crashlytics and it was a bit clogged, so I will share it.

What's wrong

Migration procedure, I went through all the work and finally built, but the following error occurred

ld: framework not found Crashlytics

approach

First, check the settings of ʻOther Linker Flags` in the following order.

TARGET - Build Settings - Other Linker Flags

1. If Crashlytics remains, rewrite it to FirebaseCrashlytics
2. Delete the Fabric if it remains, and delete the -framework on the next line.

This should solve it
