Unfortunately, the real question is why it’s so hard to accomplish any work in this IDE.<p>I used to like making small, quick changes in Xcode. Despite Xcode’s many quirks, prior to Xcode 8.x it was at least <i>possible</i> to be productive when using Xcode to edit text. Not anymore — now, if you don’t have an external editor then you will have a serious problem. Xcode lags in ways that I cannot seem to fix no matter how many settings I turn off. <i>Something</i> has started dragging the cursor in Xcode 8.x so much that it lags painfully far behind my typing, even for really small files. It......feels......like......this...... when......trying......to......change......just...... a......few......letters...... even......on......one......line. And I really wish that was an exaggeration. Worse, this even happens when you <i>delete</i> a character so you have to lag your way <i>back</i> to fix mistakes that you made.<p>I knew from the moment Interface Builder was “integrated” that Xcode would slowly grow into an unusable monolith, and I think it’s there. I simply cannot imagine a good justification for stuffing <i>that much</i> into one tool. It is possible and preferable to have a series of separate tools that still support some form of cross-communication.
