[CodeCompletion][Sema] Add fix to treat empty or single-element array literals as dictionaries when used as such In the single-element case, it is treated as the dictionary key. func takesDict(_ x: [Int: String]) {} takesDict([]) // diagnose with fixit to add missing ':' takesDict([1]) // diagnose with fixit to add missing ': <#value#>' takesDict([foo.<complete>]) // prioritise Int members in completion results - // the user just hasn't written the value yet. The above previously failed with a generic mismatch error in normal type checking (due to the literal being parsed as an array literal) and code completion could not pick up the expected type from the context.
