'assert' call can be replaced with '!!' or '?:'

Reports assert calls that check a not null value of the declared variable.

Using !! or ?: makes your code simpler.

The quick-fix replaces assert with !! or ?: operator in the variable initializer.

Example:

  fun foo(p: Array<String?>) {
      val v = p[0]
      assert(v != null, { "Should be not null" })
  }

After the quick-fix is applied:

  fun foo(p: Array<String?>) {
      val v = p[0] ?: error("Should be not null")
  }
